NODC Standard Format Marine Birds from Coastal Alaska and Puget Sound Data (1975-1980): Specimen and Feeding Studies (F031) (NCEI Accession 0014154)

Marine Bird Specimen and Feeding Studies (F031) is one of a group of seven datasets related to Marine Birds from Coastal Alaska and Puget Sound Data (1975 -1980). Each dataset uses the NODC Taxonomic Code to indicate species.

Marine Bird Specimen and Feeding Studies (F031) 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. These data were collected in 1975 - 1980 for coastal Alaska.
