Spatial patterns of contaminants in arctic seabirds

1) It is proposed that the thick-billed murre eggs collected from Coats Island in northern Hudson Bay as part of the core seabird egg monitoring program also be analyzed for perfluorinated compounds (PFCs) to allow comparison of this class of compounds between a high arctic murre colony (Prince Leopold Island) and a low arctic murre colony (Coats Island). 2) It is proposed that one additional colony (Coats Island) be added to the already approved spatial survey of thick-billed murres from Lancaster Sound (Prince Leopold Island), northern Hudson Bay (Digges Sound), Ungava Bay (Akpatok Island), and eastern Baffin Island (The Minarets/Cape Searle), and that the sample size of livers from adult seabirds being analyzed for contaminants be increased from 5 to 10 birds per species per location in order to include both sexes (5F, 5M) which would maximize spatial comparability if we get sexually skewed samples in 2008.
