COOK INLET, ALASKA i
INTRODUCTION
Cook Inlet is largely underdeveloped and does not have major
pollution problems at the present tine. Increased industrialization
through resource exploitation is expected to cause localized pollution
in the very near future. Sewage discharge from Anchorage, industrial
waste discharge from petrochemical industries,-and oil spills from
pipeline breaks and platforms are causing minor problems at present.
These possibly could have a much greater influence in the future. The
major industries now present in the Inlet are commercial fishing, pet-
roleum production, and petrochemical industries. Multiple use of water
resources in the Cook Inlet area requires that more knowledge about the
environmental conditions of the Inlet be developed. There is very little
information available describing the ecology or physical conditions of
the Inlet which would allow Judicious management of the water resources
of Cook Inlet.
LOCATION
Cook Inlet is a tidal estuary of the Gulf of Alaska and is surrounded
by glacier coverd mountains on three sides, as well as more than 100 square
miles of tidal marsh.
The estuary lies between 59 degrees and 6l.degrees thirty minutes
north latitude and longitude 1^9 degrees and 15^ degrees west. The Inlet
itself is more than 150 miles long and 50 miles wide at the mouth. The
Inlet divides at the head into two -arms, Turnagain Arm and Knik Arm,
being ^3 nautical miles and U5 nautical miles long respectively. Bordering
Cook inlet on the east are the Kenai Peninsula and the Kenai Mountains.
To the northeast at the head of the inlet lies Anchorage, the largest city
in Alaska, at the base of the Chugach Mountains, and situated at the
junction of the two arms of Cook Inlet. To the west and southwest, the
Aleutian chain borders Cok Inlet and extends down the Alaska Peninsula to
form the Aleutian Islands.
STRUCTURE
The estuary can be divided into two natural regions, a northern portion
and a southern portion, by a natural-'topographic feature, the West and
East Forelands. The bottom of the Inlet is extremely rugged containing
many'shoals and deep areas. The average depth at the mouth is 300 feet.
The area between Cape Elizabeth and Cape Douglas at the Inlet mouth is
similar to an oceanic environment. The depth of the area near the Fore-
lands averages 120 feet while the head of the Inlet rapidly shallows
to a mud bank. Turnagain arm shallows within the first 10 nautical miler,
to a large mud flat cut by many tidal channels
-------
The vaters of Knik and Turnagain Arcs , and in turn the waters of
upper Cook Inlet are influenced seasonally by the great variation of
freshwater inflow. The Sustina and Knik Rivers probably contribute
70 - 80£ of the total freshwater entering the Inlet. The maximum period
of runoff occurs during the months of July and August. During this high
runoff period much silt is carried into the head of Cook Inlet and the
Marine environment of Knik ara approaches that of a freshwater regir.e.
During winter months there is little or no flow 'and the waters become
more oceanic.
Oceanographic cruises of the State of Alaska Institute of Marine
Science during July of 1966 and 196? indicated the characteristic salinity
feature is a bending of the isohalines as a result of high salinity water
on the eastern side and low salinity water on the western side of the
Inlet. This is attributed to a greater flow of fresh water prevalent at
this time of year and to the coriolis force.
In general, the amount of total nutrients increases near the oceanic
regions of the Inlet resulting in higher productivity. The low nutrient
values in the upper Inlet may be cause for the absence of plankton, although
sediments may have a large effect in reducing the light penetration in this
region.
