FOREWORD
The Marine Protection, Research, and Sanctuaries Act of 1972, as
amended, requires that the Environmental Pro-tection Agency
develop criteria and standards governing ocean dumping of all
forms of waste. The Office of Radiation Programs has specific
responsibility for developing regulations and criteria to control
-he ocean dumping of radioactive washes.
In order to promulgate the controls necessary to protect both the
public health and safety and to assure the quality of the marine
environment with respect to any proposed dumping of radioactive
waste, the Office of Radiation Programs initiated feasibility
studies to determine whether current technologies could be
applied towards determining the fate of radioactive wastes dumped
in the past. Although the United States dumped radioactive
wastes into ocean waters from 1946 to 1970, no dumpsite surveys
had been successful in locating any of the disposal containers.
The present Operations Report provides information on the first
of the EPA. feasibility studies and is an account of the
-------

successful attempt to Locate containerized radioactive wastes
using a remote-controlled submersible. Documentation is
presented here giving some preliminary evidence of the fate of
the containerized radioactive wastes dumped in this site. A
separate technical report will also be issued early in 1976
presenting detailed analytical results of the survey.
The success, of this ocean dumpsin 2 survey was the result of
cooperation by many organizations and individuals. Special

ABSTRACT
This report presents the operational chronology and
representative photographic data, including ber.thic color places,
from an oceanographic investigation near the Farallon Islands, a
small group of islands located WSW of San Francisco, California.
The purpose of this operation was to determine the feasibility of
using a submersible to locate and investigate a site used in the
early 1950'3 for disposal of radioactive wastes and determine the
conditions of the containers, primarily 55-gallon drums. The
opera-ion employed the U.S. Navy's Cable-Controlled Underwater
Recovery Vehicle (CURV III). Radioactive waste containers were
located at 850-tner.er and 900-meter depths. Precision navigation
methods were used to ensure that the sita could be located again
for any future studies and a detailed bathymetric map of the
survey area was drawn up. Sediment grab samples and cores were
taken adjacent to the containers, and a sample of marine sponge
was collected off one of the containers. Extensive benthic
photography and video recording were utilized for documentation
of the bottom targets that were investigated. Although some
containers appeared to be partially crushed and breached, the
majority appeared intact.

INTRODUCTION
1 . 1 HISTORY OF DUMPSITE USE
The Farallon Islands are a chain of small, uninhabited islands
located approximately WSW of San Francisco, California. The
ocean durnpsite is located south and west of the islands and was
actively used from 1946-1962 for the disposal of packaged low-
level radioactive wastes. Host of -he wastes dumped there were
numerated by three Atomic Energy Commission (A.£C) contractors in
California: (1) The U.S. Naval Radiological Defense Laboratory
(now defunct), (2) The University of California Lawrence
Radiation Laboratory, and (3) The University of California
Radiation Laboratory at Berkeley. The radioactive waste disposal
operations were carried out by the U.S. Navy until July, 1959
when private companies assumed the responsibility under A EC
license. In 1962 the three radiation laboratories changed from
ocean dumping to land burial for their radioactive wastes.
1.2 SELECTION OF SURVEY AREA
h perusal of existina disposal records indicated that the actual
?arallons dumpsite area was an irregular polygon wiTih an area
exceeding 250 square miles. Such an area was far too large to
ORP-75-1 1-1
-------
FARALLCN ISLAND SURVEY
survey under the existing rime and budget constraints; therefore,
selection of a smaller survey area was mandatory. At this time,
March 1974, the Office of Radiation Programs, EPA, requested a
fact- finding study -o determine if any particular subsite or
subsites within the general dumpsite area would be most suitable
for a survey.' This study (EPA Purchase Order P4-01-03305)
involved both a literature survey and personal field contacts.
Insults of the study are presented in a report to EPA by
Interstate Electronics corporation (Report No. U550C067) .
One of the most important facts emerging from the survey was in
an article by H. waldichuk as contained in the 1960 International
Atomic Energy Agency proceedings on Disposal of Radioactive
Wastes. Here he states: "The area south of the Farallon
Islands, west of San Francisco, has the longest record on the
Pacific Coast of receiving radioactive wastes. At the original
site, 22 miles from San Francisco in a depth of about 50 fathoms
(Site 1 in Figure 1-1), three tug-loads of radioactive wastes
were dumped in 1946. Later that year, the dumping location was
changed to a point 38 miles west of San Francisco in 1,000
fathoms of water (Site 3 in Figure 1-1). This was used until
1951 when a point 30 miles from San Francisco on the 500-fathom
contour (Site 2 in Figure 1-1) was selected for dumping. Since
January, 1954 dumping has been resumed at the 1,000-fathom line."

It was now evident that this dumpsite consisted of three
distinctly separate sites.

ORP-75-1

-------
FARALLON ISLAND SURVEY
Site 2 was selected for this survey after a careful evaluation of
four main factors: (1) the inventory of wastes damped in the
site, (2) the characteristics of the radioactive waste packaging,
(3) the survey method, and (4) the specific operational
objectives.
1.2.1 Maste Inventory
As a result of the previously referenced fact-finding study, it
was determined that all of the wastes were containerized and an
estimated 150 containers were dumped at Site 1 (depth = 50
fathoms, or 300 feet), 3,600 containers were dumped at Site 2
(500 fathoms), and 44,000 containers were dumped at Site 3 (1,000
fathoms). Only radioactive wastes were dumped at Sites 1 and 2,
while Site 3 also received chemical munitions.
1.2.2 Radioactive Maste Packaging Characteristics
Almost all of the wastes dumped were packaged in 55-gallon steel
drums into which was poured concrete both for shielding and to
insure sinking. In most cases the top of the drum was removed, a
concrete bottom cap was poured, the waste was added and
surrounded by more poured concrete, and a concrete top cap was
added. In a few cases larger concrete vaults were fabricated (5
ft. x 7 ft. x 8 ft.) for larger items of contaminated equipment
or slightly higher-activity material.
1-4 ORP-75-1
-------
FARALLON ISLAND SURVEY
In November, 1950, the U. S. Navy recommended to Berkeley
Radiation Laboratory that the drums of radioactive waste destined
for ocean disposal should be equipped with a lifting eye (a cable
loop extending out from the concrete cap) made of wire cable or
reinforcing bar to permit ease of lifting and maneuvering the
drums. By mid-1951 Berkeley had implemented this recommendation
and, in turn, this technique was recommended to the Lawrence
Radiation Laboratory. By 1952 all packages for ocean disposal
were incorporating some form of lifting eye. Thus one of the
sites, Site 2, would contain radwaste packages both with and
without lifting eyes since the site was used from February 1951
to January 1954. And, in fact, this unique packaging was only
used for ' radioactive wastes. Thus location in Site 2 of a 55-
gallon drum with a concrete cap and a lifting eye would
positively identify the container as a radioacrtive waste drum
dumped between mid-1951 and January 1951, while the drums without
lifting eyes could be even more precisely dated to the first half
of 1951. This information would be particularly useful for
estimating fouling and corrosion rates of the waste containers,
1.2.3 Survey Method
The Cable-controlled Underwater Recovery Vehicle (CURV
III) (Figure 1-2), operated by the U.S. Naval Undersea Center in
San Diego, was selected to carry out the survey. It is a
tethered, unmanned submersible, is less expensive to operate than

1.2.1 Operation Objectives
(a) Determine the feasibility of a deep-ocean radioactive
waste dumpsire survey using a submersible;
(b) Obtain photographic documentation of the condition of
the drums including the degree of corrosion and fouling, and
assess relative biological abundance,
(c) obtain precisely-located sediment samples adjacent to
both intact and breached containers known to contain
radioactive wastes.
In summary, since Site 2 had, (a) precisely known coordinates
(37° 39' N, 123° 09'W), (b) wastes of a unique packaging
configuration, (c) received enough containers (approximately
3,600) to present a good chance of their being found, (d)
received the wastes over a period of time short enough (3 years)
to permit dating of observed effecrs, and (e) was deep enough to
be representative of deeper-water conditions without initially
testing the submersible system to its operating limits, then the
decision was made that an environmental survey operation at this
site would most closely fulfill the operation objectives.
1.3 SURVEY CHRONOLOGY
The plan for the actual field investigation at Site 2, the 500-
fathom site, was developed in July 19714. The go-ahead for the-
survey was received on Tuesday, August 13, 1974. The final date

available for sailing was Saturday, August 24. This tight
schedule resul-ed in numerous logistic problems all of which were
successfully overcome. The U.S. Navy Supervisor of Salvage
assigned the M/V Gear (Figure 1-3) to the program. Onloading was
completed -he nigh- of Friday, August 23, and the M/v Gear sailed
from. San Diego for the Farallons on Saturday, August 24.
Operations on station commenced on Monday, August 26, and were
completed on Friday, Auaust 30, 1974.

FAHALLON ISLAND SURVEY
Upon commencement of operation on Monday, August 26, successive
predetermined grid locations were investigated, until on
Wednesday, August 28, the first major cluster of cannisters was
located. Their unique packing configuration (i.e., 55-gallon
drums with concrete caps and lifting eyes made of wire cable
indicated without a doubt that an actual radwaste disposal site
had been reached.
It was originally planned that a final dive would be made at the
1,000-fathom {6,000 foot) disposal iste. However, the time
required to adequately sample and photograph the intermediate
depth, 500-fathom (3,000 foot) site was such that investigation
of the 1,000 fathom site had to be cancelled.
A detailed description of the planning and at-sea operations
along with a selection of significant photographs are presented
in the subsequent sections.

Section 2
OPERATIONS PLAN
A detailed and comprehensive plan was developed in order to
ensure an effective and efficient sea operation. The components
of the plan (IEC Document U46-3U9) are summarized in the
following subsections.
2,1 SURVEY AREA
The general survey area was described by NOS Chart 5402 showing
the two subareas connected by a traverse zone and their
relationship to the Farallon Islands and San Francisco shipping
traffic lanes. The first area to be searched was defined as
being along the 500-fathom contour line centered at LAT 37°39'N/
LONG 123°09'W. The second area to be searched, time permitting,
was defined as lying along the 1000-fathom contour near LAT
37°38'N and LONG 123°17«W. Eathymetric charts of the noted area
were procured for use in tracking during the search operation.
2.2 PRE-SAILING OPERATIONS
The pre-sailing opera-ions provided definitions for the following
important areas:
ORP-75-1 2-1
-------
FARALLON ISLAND SURVEY
1. Operation Schedules. - This schedule defined the
operational times from mobilization through
demobilization as 19 August 197U to 31 August 1974 wirh
possible extension through 2 September if required.
2. Participant Responsibilities. - The operational
responsibilities for each of the participating
organizations were defined. These included pre-
sailing, as well as sea operation tasks to be
completed. The agencies participating in the operation
were:
(a) U. S. Environmental Protection Agency (EPA),
participated as lead agency in determination of
general operational policy, planning, and funding.
(b) Interstate Electronics Corporation (IEC) , served
as mission contractor.
-------
FARALLON ISLAND SURVEY
provided ship board radiation monitoring and
analysis.
3. Preparation for Sea Operations. - The preparations for
sea operations included factors such as staging areas,
ship loading, provisioning, and final boarding
schedules.
2.3 SHIP OPERATIONS
Departure and arrival schedules were established for the ports of
San Diego and San Francisco. In-transit plans and ship-to-shore
communication channels were established.
2.4 SURVEY OPERATIONS
A survey site operational plan was developed and key decision
points were introduced with respect to operational delays or
termination of the operation. These decision points were a
function of impending weather and/or sea-state condition and
equipment performance. Details of the operational plan included
the following:
1. CURV III Search Operations - describing the
pre-established sampling pattern, target identification
and verification, photo requirements, sample collection

requirements, course deviation authority, vehicle
safety, etc.
2. Grab Sample Operation - describing precise navigation
requirements along pre-established track, sampling
equipment operation, time requirements, and succeeding
sampling procedures.
3. Contingencies - developed principally as a function
of impending weather and/or sea-state criteria. Times
and points of survey operation were defined and ship
and crew safety requirements considered.

EQUIPMENT AND INSTRUMENTATION
3. 1 CURV III
CURV TTT (Figure 1-2) is an unmanned, tethered,
surface-controlled vehicle as the acronym CURV (Cable Controlled
Underwater Recovery Vehicle) readily explains. Physically, CURV
is a framework with motors, hydraulic systems and cameras
attached. It has syntactic foam blocks mounted to provide
balance and a slight, positive buoyancy. Its overall shape
resembles a rectangular box. CURV is linked to power and control
systems by a multiconductor underwater cable. The weight of the
cable over-the-side is borne by a nylon pendant that is
periodically tied to the electrical cable. The last 600 feet of
cable nearest CURV (the tether) is made neutrally buoyant by
attaching blocks of foam. CURV is powered and controlled from
the surface and has unlimited bottom-time capabilities. A
control console provides visual and sonar maneuvering inputs plus
depth and vehicle attitude sensors.
The length of the neutrally buoyant tether is the maximum radius
for a search by the vehicle. CURV is powered forward and reverse
by port and starboard motors and can be powered up and down
ORP-75-1 3-1
-------
FARALLON ISLAND SURVEY
by a vertical motor; it is slightly buoyant so it must be powered
down to the bottom. CURV is highly maneuverable - -both en and
above the bot-com. A selection of tools (grasping claw, clamshell
scoop, hooks, grapnels) provides good adaptability to variable
sampling requirements.
CURV has an A.MTEX/STRAZA SLAQ-603 sonar system that scans an area
120° over a distance up to 800 yards in front of the vehicle.
The SLAD (Sonar, Locator, Altimeter, Depthometer) system provides
visual (cathode ray tube) and aural signals from a high
resolution, rapid scan, continuous transmission frequency
modulated sonar system for tracking active or passive targets.
The high resolution of the system gives the remote operator the
necessary precise location of the target relative to the
underwater vehicle. At the same time, the system provides the
operators with navigation data that establishes the location of
the vehicle with respect to altitude above the ocean floor, and
depth below the surface. The sonar display unit on the surface
control console provides aural signals and visual displays of
target range and bearing, relative to the bow of the underwater
vehicle. The CRT sweep displays a 120° sector centered about the
vehicle bow.
Limitations of CURV are cable length and weather. Maximum depth
of operation is 10,000 ft. with normal depth of operation limited
3-2 ORP-75-1
-------
FARALLCN ISLAND SURVEY
to 7,000 ft. The actual operating depth has not exceeded 5,500
ft to date. Weather limits are about sea-state U and are related
to launch and recovery dangers.
For documentation purposes and near-bottom navigation, CURV has
two television cameras and one 35-mm camera, all
remote-controlled from a control van. The television cameras are
solid-state vidicon cameras with a water-corrected lens and 54°
viewing angle. The 35-mm camera is an EGSG color with
200-watt/sec strobe. Lighting is from 100- or 250-watt
pressure-balanced, mercury vapor spotlights.
The initial mode of operation with CURV was a search and traverse
method. A pre-established area of greatest probability for
locating containers was outlined for a series of traverses. In
actual operations, the traverse consisted of a series of searches
performed along the desired course with the SLAB 603 sonar system
in the following manner:
1. Upon initial setdown of CURV, a sonar search of four
quadrants was made to "box the compass". This covered
a radius of 800 yards.
2. If no contacts were identified that were considered
significant, a traverse in the desired direction, with
the sonar on, was made for about 600 to 800 yards.
3. Again a quadrant search was made.
ORP-75-1 3-3
-------
FARALLCN ISLAND SURVEY
4. If targets within the tether range (600 feet) were
located, an immediate investigation was made. If no
targets were identified, the traverse continued.
Targets out of tether range were approached by moving
the ship.
5. Targets of interest that were located by sonar were
approached by using the sonar and, if on visual contact
were still of interest, the 35-mm camera and the video
tape recorder was utilized for documentation purposes.
During the investigation of the dumpsite survey area, cores (3.8
cm. diameter x U8 cm. deep) were taken with an adaption of the
manipulator arm. Four cores were available on each dive of the
CUKV III. The coring configuration utilized by CURV III is shown
in Figure 3-1. Each polycarbonate core tube was provided with a
one-way finger closure to prevent sediment loss. A Shipek grab
had also been mounted on CURV and one grab was available on each
dive.

FARALLCN ISLAND SURVEY
Four mercator grids at a scale of 1:24,000 were pre-plotted
covering the area from Lat. 37°35'N to 37°U5'N and from Long.
123°00'W to 123°20«W. A fifth grid covering the potential
control area from Lat. 37°10'N to 37°15'N and Long. 123°00'W to
123°10'W was also prepared. The contouring from NOS Chart 5402
was photographically enlarged and added to the grids to form -he
base charts of the area to be surveyed.
Offshore Navigation Services, INC. (QMS), Ventura, California,
was retained to provide a Motorola RPS (Radio Positioning System)
network for the survey area. The system instrumentation included
a Motorola Model III Mini-Ranger and rotary scanning antenna for
use aboard the vessel and three transponders located over bench
marks at Point Reyes, Mount Tamalpais and Montara Mountain. The
Motorola Mini-Ranger digitally displays the range, in meters,
from shore transponders and has a probable range error of ±3
meters at 40 nautical miles. Thus providing a highly accurate
means of navigation and track plotting.
Because the search pattern to be used during the survey would be
dependent upon wind and current direction, precise vessel track
lines could not be precalculated. Instead, transponder ranges to
46 points within the survey area and four points within the
control area were pre-computed at selected intersections of the
one-minute mercator grid lines on the base charts. Also added to
3-6 ORP-75-1
-------

the base char-ts were range arcs from the three transponder
stations at intervals of 500 meters.
The resultant plotting and tracking charts are nearly the same as
the original plot. The scale of 1:24,000 was changed to 1:25,000
to allow easy measurements using an ordinary metric ruler.
3.2.2 Radio Positioning System
A. . Motorola Mini-Ranger III positioning system was selected for
use both as a primary navigation aid and for positioning during
the operation. The prime factor in choosing it was its
superiority over more conventional navigation systems. The
Motorola Mini-Ranger III is a short-range, pulse radar system.
It consists of a range console, two or three shore
transponders, rotary scanning antenna, and a receiver/transmitter
unit. In operation, the base station, onboard the ship, emits
interrogation signals which elicit a reply pulse from two
reference stations. The elapsed time from beginning of
interrogation to arrival of reply pulses is measured and
converted to range data. This data, in meters, is displayed
simultaneously on two sets of light emitting diodes mounted in
the range console. A precise position of the vessel can be
plotted at any instant by this trilateration technique.
ORP-75-1 3-7
-------
FARALLCN ISLAND SURVEY
The scanning antenna was installed on the M/V Gear above rhe CURV
control van located on the roof of the wheelhouse and connected
-o the transceiver/display unit placed in the plotting room.
Transponders were placed on the bench marks during the weekend of
2U-25 August 1974 while the M/V Gear was in rransit from San
Diego to San Francisco.
Operation was in the 5400 to 5600 mHz band which prevented
interference from the ship's radar. The system utilizes pulsed
radar type transmissions to determine the distances from the
survey vehicle -o the reference transponders. The intersection
of these range arcs provides a highly accurate fix. Since the
information is continually updated, the successive fixes can. be
used for track plotting. Such is not the case with satellite
systems in which the fix is obtained only during the pass. This
high-accuracy track plotting feature was the prime reason for
selection of this equipment.
3.2.3 Precision Depth Recorder
The precision depth recorder selected was a Hydro Products Model
UOOO, GDR-IC-19T Gifft recorder. This instrument incorporates a
number of features that were particularly desirable for this
operation. Basically, it is a complete echosounder with a
1000-watt integral acoustic transceiver. Operating frequency was
12 kHz which permitted use of the ship's standard UQM-type,
3-8 ORP-75-1
-------
FARALLON ISLAND SURVEY
hull-mounted transducer. A built-in programmer provided the
necessary degree of versatility that was required to insure high
resolution without interfering artifacts. Recording was done on
high resolution, electrosensitive, wet recording paper. Accurate
water depths had to be known during CURV operations to determine
the correct amount of cable payout. The main cable could not be
allowed to drag on bottom, and if it was held too high, the
excursion area of the vehicle would be reduced.
3.3 RADIATION MONITORING AND ANALYSIS EQUIPMENT
The objectives of having radiation monitoring and measuring
equipment on board was two-fold:
1. Monitoring to detect the presence of any potential
harmful radiation in either the samples collected or
sampling equipment used in the vicinity of ~he
radioactive waste dumpsites.
2. Measuring equipment to more precisely identify and
quantify the specific radionuclides present and provide
on-going information to identify sites which might be
more thoroughly sampled before returning to shore.

3.U CONTINGENCY SAMPLING PROGRAM
In the event of a serious CURV malfunction, a backup sampling and
in situ recording system was assembled. It consisted of: A
hydrographic winch equipped with 10,000 ft. of 1/4" hydrographic
wire; an InterOcean 550 STD recorder; an InterOcean 3-1055 pinger
(12 KHz), and a Shipek grab sampler.
The winch was a "Sendix Deep-Sea winch" with capacity for 23,000
feet of 1/4" wire rope. The wire was U.S. Steel 1/4" galvanized
3x19 torque-balanced wire rope. The STD incorporated internal
recording, battery-powered system from InterOcean Systems, Inc.
It had an optional dissolved-oxygen sensor and measured
conductivity, temperature, depth and DO, two parameters (C, T) on
the down cast and one (DO) on the upcast, all plotted versus
depth. The 12 KHz pinger matched the UQN-1 ship fathometer
transducer. It was used to monitor the height off the bottom of
the instrument packages and equipment.
The Shipek grab sampler was a Hydro Products Model 860, identical
to the one used on the CURV III. The sample is approximately 60
square centimeters in surface by 14 centimeters deep at the
center. It is particularly well adapted for pickup of benthos
organisms living at or immediately below the sediment-water
interface.
3-12 ORP-75-1
-------
FARALLCN ISLAND SURVEY
The instruments were arrayed on the wire in the following
fashion: First, the Shipek sampler; then the STD profiler 10
meters above followed by the pinger one meter above the STD
profiler. This arrangement prevents the STD from touching the
bottom. The pinger was to be tracked on the depth recorder which
allowed lowering rare to be slowed to 1/2 ft/sec at a distance
100 meters from the bottom and then stopped at 5 meters from the
bottom.
The package was deployed on August 26 after a CURV malfunction.
Contact with the pinger was lost near the bottom, and when
reestablished, it appeared that the package did touch bottom.
The Shipek successfully collected a sample, but the STD profiler
had malfunctioned and no water column data was collected.
3.5 MALFUNCTION OF TH2 STD/DO PROFILER
Prior to launching, the Model 550 profiler was checked out and
was operating. Upon recovery, it was found that the profiler had
failed. An IEC electronic engineer and an electronic technician
of the Environmental Protection Agency checked out the unit
onboard the ship to determine the cause of failure. The first
problem uncovered was that the pen assemblies had not dropped
onto the chart paper, although the pen lifters had been placed in
the down position. It was determined that friction within the
mechanism was such that the pens would not drop in place unless
ORP-75-1 3-13
-------
FARALLOW ISLAND SURVEY
an upward pull was given on the pen lif-er knob. Since the chart
recording assembly is not visible without removing the pressure
housing, there is no positive way of knowing if the pens are in
position. The next fault was indicated fay improper readings at
the test points on the voltage regulator card. Visual inspection
revealed a cold solder joint which had fallen off of a printed
circuit board connector. Resoldering of this wire reestablished
correct readings at the test points on the voltage regulator
board. Inspection of the plug-in boards indicated components
improperly mounted. Specific examples included clusters of
capacitors whose leads were twisted together and s-uffed into
integrated circuit sockets. Although replacement of the power
supply lead resulted in proper voltages on the voltage regulator
board the unit was still not fully operational. Further visual
inspection revealed the cause. Leads going to the servo
amplifier boards were improperly dressed. Mechanical design was
such that there was no way to prevent abrasion when the pressure-
proof housing was removed and replaced as is necessary during
normal test and operations. Inspection revealed that abrasion
had, indeed, been the problem, and that the insulation on the
twisted wiring had been worn off completely in several places.
This had resulted in a short circuit destroying one or the
semi-conductors. Since no spares were provided with the unit, it
was impossible to reoair it in the field.
3-1U ORP-75-1
-------
FARALLON ISLAND SURVEY
No moisture entered the unit during the cast. However, the
necessity for opening the unit on deck to turn the power on and
drop the pens allows moist warm air to enter the unit. During
deployment, external temperatures in the range of !4°C are
normally encountered resulting in condensation of moisture on the
circuit board contacts and electronic components.

The following summary of the Operations Leg provides an outline
of the general chronology of the survey including: . the daily
routine; normal and special operations; the time required to
perform the various tasks; the areas covered by the survey; some
on-site observations and operational problems encountered. It
will be noted that che basic schedule in the Operation Plan of
Section 2 was maintained except for surveying of the control
site. The allotted time was used to maJce additional observations
at the 500 fathom disposal site. Under operating conditions,
some details of the operation Plan were deemed not to be
feasible; these included multiple dives per day and bottom
traversing between planned sampling stations. All courses
mentioned in this log are referenced to true north. A brief

U.2 Shin* s Positioning
During the hours from 0000 to 0600, M/V Gear maintained steerage
way by slowly cruising up and down wind in an area off the
Farallon Islands, avoiding the major San Francisco shipping
lanes. During these early morning hours, the ship was navigated
using radar ranges and bearings from the nearby islands.
Accuracy of positioning to within 1/2 mile was easily obtainable.
During the usual operating hours of the day, from 0600 until CURV
recovery was started, all positioning was done by precision fixes
ORP-75-1
4-11
-------
FARALLCN ISLAND SURVEY
using the Motorola EPS system, usually at five-minute intervals.
All precision fixes were logged and plotted in the following
manner:
1. As the sweep-second hand of the ship's chronometer
passed "0", the event marker of r:he Gifft recorder and
the "Hold" button of the Mini-Ranger were pressed.
2. The time and depth in meters were annotated on the
fathogram and the time and two ranges entered on the
daily position log sheet. The cwo ranges normally used
were from Point Reyes and from Mount Tamalpais, known
as "Head" and "Ridge". These were being updated every
few seconds, whereas responses from rhe transponder on
Montara Mountain frequency required 10 to 15 seconds.
The Mini-Ranger "Hold" button was released after
logging the two digital readouts.
3. The fix was then plotted on the base char-c by manually
scaling from the nearest range arcs. The scale was
marked in 100-meter graduations that were spaced 4.16
mm apart (1:24,000). Even coarse pencil lines and
points (1 mm) gave a resolution of ±15 meters and
careful work would give a resolution within 10 meters.
4. To avoid cluttering up the base chart, most of the
tracking points were periodically erased except for
•chose with special significance. All or any portion of
the ship's tracks may be replotted from the log.
4-12 ORP-75-1
-------
FARALLON ISLAND SURVEY
After CURV recovery had started, the fathometer was shut down and
logging of the fixes stopped. However, the RPS was kept on and
continuously monitored in the event that the CURV lifting line
and cable parted and the vehicle lost its positive buoyancy.
Thus, its precise location would be known for subsequent
recovery.
U.3 Bathymetry
The Gifft recorder was operated approximately through the same
period as the RPS logging. For the depth range of 700 to 1000
meters over most of the surveyed area, the most convenient
full-scale range was 300 meters (1.5 mm = 1m) with depth
graduations at 20-meter intervals. Thus, depths to within five
meters could be read with a quick glance, to within two meters
with normal "eye balling" and within one meter using multiple
dividers. The best trace, during CURV operations, was obtained
using a gating program of three transmitting pulses followed by
three receive/write pulses at a gain of 10. Gains of 20 to 100
were required when the ship was backing or during the special
bathymetric survey when the ship's speed was five knots. A paper
feed rate of 2 cm per minute was adequate for resolution even
over the rough bottom at the five-knot survey speed. During the
one-to-two knot transit speeds and station keeping periods, this
feed rate was maintained. Trying to save paper by slowing the
ORP-75-1 4-13
-------
FARALLCN ISLAND SURVEY
feed rate caused the wet process paper ~o dry out under the
moving stylus and wrinkling resulted.
As could be expec-ced, the contouring on the published charts was
highly generalized compared to what may be plot-ted a- a scale of
1:25,000. For example, the 500-fathom survey area is shown on
NOS Chart 5'402 as a very broadly rounded nose, gently plunging to
the west between two intermediate-sized sea-valleys. Because it
was shown to be one of the smoothest areas on the upper
continental slope of central California, no problems were
anticipated in making CURV transits or operating the sonar in any
direction desired. This area actually is a series of ridges and
gullies with slopes up to 30° and numerous ledges and mounds with
local relief exceeding 40 meters. A special bathymetric charr,
at a scale of 1:10,417, with a contour interval of 10 meters, was
prepared from the barhymetric and navigational data. This chart
is presented as Figure 4-2.
4.4 Drift Determinations
The first phase of the daily operation was to determine drift
rate and direction of the ship. This was done because during the
launching of CURV, the M/V Gear must not turn its screws for a
period of five to fifteen minutes while CURV is driven around the
stern and up to the bow of the ship. The drift rate and
direction was determined by plotting a series of precision fixes
4-14 ORP-75-1

a~ fivr-minu-e intervals for a period of one-half hour or more,
wi-.h -he ship lying deaa in the water. During -he survey period,
-he drif- ranged from 0.5 to 1.0 knots and was generally to -he
southeast. 'With -his information, a launch point was established
fifteen minuses updrift of the selec-ted bottom target site.
In future launches of -he CURV from M/V Gear, this procedure of
obtaining drift rate and direction, and determining a launch
point updrift from the -arget point may be minimized because of
-ne following factors:
1. The CURV vehicle and its cable act as a sea anchor
after launching and the drift rate is approximately
half -chat of the ship alone.
2. The ship is headed into the wind and sea at the start
of the launch and several minutes elapse before it
falls off and lays broadside to the wind. Thus, the
full effect, of the wind is not felt during this
interval.

SHIPBOARD RADIOANALYSIS
The I?A Office of Radiation Programs —Las Vegas Facility (ORP-
LVF) and -he Environmental Monitoring and Support Laboratory, Las
Vegas (EMSL-LV) provided shipboard radiation monitoring and
measuring services. These included radiation monitoring of the
CURV and associa-ed equipment upon recovery from each dive and
counting of sediment samples for radioactivity.
Personnel radiation dosimeters were provided for all personnel
involved with handling the CURV who could conceivably be exposed
to radiation from recovered samples. Conventional beta-gamma
film dosimeters were provided by NUC for the deck crews and a
thermoluminescent dosimeter (TLD), provided by EPA, was worn by
the Murphy Pacific diver, -flo personnel radiation exposures above
expected background were recorded for any individual on the
project.
The radiation monitoring and counting equipment carried on the
M/V Gear for the project are described in Section 3.3 of this
report. Figure 5-1 illustrates the temporary laboratory which
was installed in the ship's carpentry shop.

SEDIMENT CONTROL SAMPLES
Control samples were obtained through correspondence with the
following Pacific coast schools and universities: Humboldt State
University, .Oregon State University, Scripps Institution of
Oceanography, U.S. Naval Postgraduate School, University of
Southern California, and the University of Washington. To the
extent practicable, certain criteria were adhered to in the
selection of samples; viz., collected near 1000 m contour, mass
of 500-1000 grams and representing relatively undisturbed surface
sediment where possible.
Difficulties encountered obtaining samples meeting these criteria
warrant some discussion. Standardization of collection depth
from sample to sample was impossible; also, samples at depths as
great as 1000 meters were not generally available. Apparently,
this stems from the large quantity of material requested (most
universities only retain small quantities of each sample they
collect), and the significant academic interest in the
continental shelf and continental slope. Variance in sampling
devices caused differences in sediment quality (e.g., grab

samples are more susceptible to sediment wash-out than box
cores) .
Although this method of gathering control samples presented many
problems, it was the best system employable under existing time

PHOTOGRAPHIC DOCUMENTATION
All of the following photographs were taken at a depth of
approximately 900 meters, and all but the last two photos were
taken with a 35-mm EG5G underwater camera.
Frame 357 Fifty-five gallon radioactive waste barrel showing
a moderate amount of hydrostatic crushing. A wire
lifting eye is protruding from the concrete cap at
the left end of the barrel. A deepsea sole,
Embassichythys bathybius, is occupying the upper
indented area.
Frame 364 This barrel was lifted by the manipulator arm of
CURV III to show the limited extent of barrel
penetration into the sediment. The sediment under
the barrel shows black bands that may indicate
anoxic corrosion of that part of the barrel in
direct contact with the sediment.
Frame 367 Another example of hydrostatic crushing at the
center of a barrel, a common phenomenon in this
dumpsi-e. A long lifting eye of wire rope is
visible protruding from the concrete cap at the

right end of the barrel. The CURV III manipulator
and its hydraulic hose system are in the left
foreground.
Frame 372 Closeup view of the concrete cap in a typical
radwaste barrel at this site. These concrete caps
were generally about 20 cm to 30 cm thick at borh
ends of -che barrel. CURV III manipulator
hydraulic hoses are in the foreground.
Frame 374 Barrel in foreground shows effect of hydrostatic
pressure in warping the length of the barrel. An
anemone is attached to the concrete cap. Another
barrel with a lifting eye is seen in the
background.
Frame 379 View of underside of barrel that was rolled over.
Good view of lifting eye in the concrete cap.
Black deposits (sulfides) typical of anoxic
corrosion are visible and appear to start a short
dis-ance below the sediment surface.
Frame 388 A barrel with no evidence of hydrostatic crushing.
A coating of fine, minimally disturbed sediments
is prominent on the upper area of the barrel
indicating the relatively small amount of sediment
deposited since disposal 22 to 24 years ago. The
metal cap (bottom) end of the barrel is at the
lower right of the photo.

Frame 403 Closeup view of a lifting eye on a barrel. This
barrel's concrete cap is recessed inside the
barrel end as contrasted to Frame 357 where the
concrete bulges above the rim of the barrel.1 Note
barrel immediately adjacent in background, also
flatfish partly visible beneath sediment cloud.
Frame 404 View of upper surface of barrel shown in Frame
403. This carrel is imploded and may have been
breached as evidenced by the sharp edges of the
crushed area. TV viewing also indicated this. A
photograph of this crushed area, taken from the
poorer quality videotape record, is shown in the
TV 2 photo; the angle of the photograph is
different from Frame 404.
Frame 409 Upright barrel showing large vase sponge attached
to barrel. This sponge is of the Class
Hexactinellida and probably represents a new
genus.z
On March 12, 1954 the U.S. Navy stated that henceforth all
55-gallon drums containing radioactive waste must have
concrete caps recessed at least 1-1/2 inches to permit
loading and handling by chime hooks.

Frame 410 This photo shows the type of clustering of barrels
that was typical of the sites. Three barrels are
in the field of the camera (camera range was about
12 feet). This clustering supports the fact that
the barrels were all released at one time from a
hopper-type barge rather than being dumped
individually over the side.
Frame 413 Fifty-five-gallon drum viewed from the bottom end
(metal cap). A thornyhead fish, either
Sebastolobus alascanus (short-spined) or
Sebastolohus altivelis (long-spined) , and a tanner
crab, chionoecetes tar.neri, are visible near the
barrel end.
Frame 415 An example of the ex-tensive hydrostatic crushing
some barrels exhibited.. Implosion of most
barrels was in the center third as shown here.
Frame 484 Barrel with atypical crushing at the concrete cap
end. It would appear that the waste, containing
air voids, was packaged without an adequate
concrete plug at this end.
Frame 186 Undecipherable lettering is visible on this
end-crushed barrel. Two Sebastolobus are at the
left front of the barrel. Two anemones on an
unidentified substrate are immediately in front of
the barrel.

Frame 492 Example of the typical implosion pattern of the
many barrels sighted. This implosion pattern
corresponds to those from laboratory and field
experiments on test containers at the similar
pressures and depths. (Pneumodynamics Corp.;
1961; Pearce, et al; 1963.) The crushed portion
is a series of regular indentations with a slight
twist in the longitudinal axis. A closed cylinder
under high external hydrostatic pressure would
collapse similarly.
Frame 494 A barrel, pushed over by CURV III, that has
numerous sponges attached. This is a good example
of the many similarly-sighted barrels showing the
potential for biological action on the container,
and the propensity of some invertebrates to seek
this substrate and other hard substrates for
attachment.
Frame 496 Upright barrel with large sponge of the new genus
of Hexactinellida attached. The area near the top
left edge of the barrel, where some hydrozoans are
seen, appears to be breached. No-ce that this

other than concrete were being conducted.
Frame 522 When the CURV manipulator attempted to remove a
sponge sample from this barrel also shown in Frame
496, the sponge fell away leaving the corroded
inner matrix of the barrel exposed. The detached
sponge still retained a large piece of the barrel
along its base of attachment (not visible here) .
The metal of the barrel was corroded and flaky and
the barrel may have had a bitumen liner. Note

CONCLUSIONS AND RECOMMENDATIONS
8.1 OPERATIONAL RECOMMENDATIONS
The field survey conclusively demonstrated the ability of the
tethered underwater vehicle, CURV III', to perform
highly-sophisticated investigative tasks at a depth of 500
fathoms (3,000 feet.) Of particular importance was the ability
of CURV III to remain on a survey station for long periods of
time.
As with any complex operation, there were areas that could be
improved. The most important of these was the station-keeping
ability of the CURV III support ship. This is a function of the
type of surface support vessel. Station keeping with the M/V
Gear was satisfactory when the class of vessel was considered.
However, there were significant problems staying on station
throughout the operation since the ship lacked lateral
positioning equipment such as bow or stern thrusters. The launch
and recovery of the CURV III also needed modification. The
periods of highest risk to personnel and CURV III occurred during
launch and recovery. In a July, 1974, operation for the Army
Corps of Engineers, damage during launch was sufficient to abort
ORP-75-1 8-1
-------
FARALLON ISLAND SURVEY
the operation. A similar near-mishap occurred during this
operation when a wave s-ruck the ship, at a critical time during
the launch, and caused CURV III to impact the vessel's side.
Although the vehicle went on to perform its mission, the shock
had been great enough to cause failure of the 35mm underwater
camera spooling mechanism for one complete dive. For future
programs the station keeping problem and launch/recovery risks
could be minimized by the use of a support vessel better designed
for the CURV III, such as the YFNX-30 boat operated by the Naval
Undersea Center, although this would require a longer transit
time to the study sice and a second ship to tow the YFNX-30 boavi.
There were several technical areas that could be improved by
equipment modifications to the CURV III system. Although these
problems were apparent, solutions ' were not implemented due ^o
funding limitations. The following improvements should be
considered for incorporation in future operations:
1. Precise 60 Hz Power Source - The power supply for the
TV videotape recorder is presently a portable diesel
generator. Unfor-unately, frequency regulation is not
precise enough to guarantee the ability to playback the
video tape recordings from machines connected to shore
60 Hz mains. In the case of the Farallon operation,
the original video tapes could not be played back on
shore without extensive processing. This processing
I-2 ORP-75-1
-------
FARALLQN ISLAND SURVEY
resulted in the loss of resolution and, consequently,
in the loss of valuable information. A. separate,
stable-frequency power supply should be installed for
the videotape equipment.
2. Underwater Positioning - Precise location of the
underwater vehicle with relation to the surface support
ship was impossible. Use of the BALD (Boat Acoustic
Locating Device) equipment provided a bearing but r.ot a
precise position. Without precise location
information, the full capabilities of the vehicle
cannot be realized. A sonar-type position plotting
system should be considered.
3. Operational Convenience
a. The video tape recorder should be modified for
remote control to permit the unit to be secured in
the cabinet, control of the recorder was
inconvenient. Use of the instrument on the desk
could be hazardous in rough seas. Voice recording
should be used extensively by an expert observer.
b. Interior communications (between deck, control
van, plotting room, etc.) was difficult. The 27
mKz. handytalkies were noisy, and the operation was
not convenient for the crew. Use of combined
headset/FM transceivers should be considered.
ORP-75-1 8-3
-------
FARALLCN ISLAND SURVEY
c. Plotting could be greatly expedited by use of a
digital printer connected to the 3CD (Binary Coded
Decimal) output of the Radio Positioning System.
This would provide a digital printout: of the
ranges, eliminating the need for manual plotting
and the possibility of human error. The system
could be further automated by incorporating a
standard American Standard Code for Information
Interchange tape punch or mag tape recorder so
that -he plot data would be ready for computer
entry without further hand processing.
2 CONCLUSIONS WITH RECOMMENDATIONS FOR FUTURE OPERATIONS
1. Review of the benthic photographs by members of the
scientific community has resulted in expression of the
need for collecting deepwater biological specimens in
future operations. To do this properly, a biologist
skilled in the identification of deepwater benthic
species should be onboard as part of the scientific
team to perform as much at-sea visual identification as
possible.
2. There is a significant lack of information on ocean
currents in deepwater dumpsite areas. Both short and
long-term current measurements should be taken around
dumpsites. Salinity-Tempera-ure-Depth (STD) profiles
8-4 ORP-75-1
-------
FAHALLON ISLAND SURVEY
should also be taken to identify any water masses
present which could ultimately act as pollutant
dispersents.
3. Sediments are the most important indicators of
short-term, aperiodic, and/or low-level radionuclide
releases in areas with large dilution capacities. Any
future operations should include extensive sediment;
collection for analysis of the presence and
distribution of any released radionuclides.
4. Selected radioactive waste packages should be recovered
for corrosion analysis of the metal sheath, and leach
rate determinations of the concrete or other matrix
material.
In summary, feasibility of using the CURV III for radioactive
waste disposal site monitoring has been successfully demonstrated
at the 500-fathom site near the Farallon Islands and has provided
the following information:
1. The radioactive wastes were found in the general
dumpsite area as reported by Joseph, 1957.
2. The containers had the unique packaging configuration
described in the disposal records.
3. None of these radioactive waste packages showed any
evidence of failure of the concrete plugs either by
ORP-7'5-1 8-5
-------
FARALLCN ISLAND SURVEY
being forced inward or popped out due to the high
hydrostatic pressure.
U. The unmanned undersea vehicle performed as required.
5. The photographic documentation (as presented in Section
7) provided useful information on the condition of the
drums.
6. Precisely-located core samples could be obtained next
to radioactive waste containers, in this case at
Station 13 (A and B) (Table 5-1) .
7. The biological activity in the area was high with at
least one commercial species of fish, Anoplopoma (sable
fish) being present in the dumpsite area.
It has now been established that varying degrees of container
deformation have occurred to many of the 55-gallon radioactive
waste drums observed at the 500-fathom depth. The question now
arises: What sort of predictions can be made about radioactive
waste container integrity at the 1/000-fathom dumpsite,
considering that 2,000 meters {approximately 1,100 fathoms or
6,600 feet) is the present internationally acceptable minimum
disposal depth for ocean dumping of low-level radioactive wastes?
It is recommended that a subsequent survey be made at the
1,000-fathom radioactive waste dumpsite near the Farallon
Islands.
