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