Marine bird specimen and other data from the Beaufort/Simpson Lagoon as part of the Outer Continental Shelf Environmental Assessment Program (OCSEAP) from 25 June 1978 to 23 September 1978 (NODC Accession 8000051)

Marine bird specimen and other data were collected from the Beaufort/Simpson Lagoon from 25 June 1978 to 23 September 1978. Data were collected by the Alaska Research Association and LGL LTD. as part of the Outer Continental Shelf Environmental Assessment Program (OCSEAP). Data were processed by NODC to the NODC standard F031 Marine Bird Specimen and Feeding Studies format. Full format description is available from the NODC homepage at www.nodc.noaa.gov/. An analog file for this accession is available from NODC user services.

The F031 format contains data from laboratory examination of marine bird specimens collected in the field and analysis of food sample contents to determine prey species and characteristics. These data provide information on population dynamics and trophic relationships. Position, date and time are reported for each sample station, along with environmental data at the sample site including ice conditions, if appropriate. Environmental data may include air temperature and pressure, wind direction and speed, sea surface temperature, tide conditions and habitat and microenvironment descriptors. Species identification, general biological condition (e.g., age, sex, color), weight, and body dimensions are reported for each specimen (multiple specimens may be collected at each sample site). If food samples are taken, food sample source and characteristics are reported. From food sample analysis, prey species are identified and for each such species further detailed data may be presented including frequency distribution of prey or prey part length and weight.
