Summary

These data are part of the Gulf Watch Alaska (GWA) long-term monitoring program and contain diet data from Black-legged Kittiwakes (BLKI), Rhinoceros Auklets (RHAU), and Tufted puffins (TUPU) located on Middleton Island in Prince William Sound, Gulf of Alaska. The first table consists of information on seabird diet samples including the sampling method and number of prey types identified per sample ("seabirdDiets_foodSample_middletonIsland.csv"). The second table is similar to the first table, however, the samples have been subdivided by individual prey species ("seabirdDiets_samplePrey_middletonIsland.csv"). The third table consists of information specific to sampled prey items, such as prey taxa identification and morphometrics ("seabirdDiets_preyItems_middletonIsland.csv"). [...]

Purpose

These data on predator (seabird) diets can provide quantitative information on abundance, distribution, temporal variability, condition and community structure of local prey stocks. This long-term seabird diet data from Middleton Island can provide a useful index of long-term trends in Prince William Sound, Alaska and is the longest continuous dataset on forage fish in the region.
