Alaska Marine Bird Specimen And Feeding Studies From 1975-1980

Coastal Alaska and Puget Sound data from 1975-1980 contains laboratory examination records of marine bird specimens and analysis of food samples. The dataset provides information on population dynamics and trophic relationships, with data collected by NOAA NCEI. Records include sample station position, date, time, environmental conditions, and biological measurements for each specimen.

Use Cases

• Analyze prey species composition and frequency distribution from food sample analysis data to model trophic relationships.
• Correlate bird specimen biological condition (age, sex, weight, body dimensions) with environmental data like sea surface temperature and ice conditions.
• Map species identification and collection events using reported position, date, and time for each sample station.
• Study habitat descriptors and microenvironment data in relation to general biological condition of collected specimens.

Strengths

• Data collected over a 5-year period from 1975 to 1980.
• Includes multiple data types: environmental measurements, biological specimens, and prey analysis.

Limitations

• Data is temporally stale, with collection ending over 40 years ago.
• Sample size and geographic coverage within coastal Alaska and Puget Sound are unspecified.
