Standard Operating Procedure for
Meteorological Data Aboard the
RV/Lake Guardian
1.0 Scope and Application
1.1 This method, applicable to all surveillance cruises performed by the RV/Lake Guardian was in
effect during the calendar years 1994 and 1995.
1.2 These procedures are implemented while the vessel is underway and while occupying a sampling
station.
2.0 Summary of Method
The officer in charge of the bridge is responsible for implementing the procedures herein described.
On the hour, the following parameters are recorded in the ship's log: wind speed and direction,
wave height and direction, air temperature, barometric pressure, visibility, present weather
conditions and heading (when underway). For each significant event the time and description is
recorded. At each sampling station, the station identification, arrival time, departure time, wind
speed and direction, wave height and direction, barometric pressure, water depth, air temperature,
geographic location (loran and/or GPS), and final location (if vessel has drifted during sampling)
are recorded. The deviation of the ship time from Greenwich mean time is recorded daily.
