2/4 #WSTC6 #ContSesh2 We necropsied 377 bycatch and stranded GRSH to collect samples and dem. info. Most birds were collected after foraging in GoM for several mths, but also obtained juvs on their way North, post-breeding adults. Sample subsets analyzed for range of pollutants.
3/4 #WSTC6 #ContSesh2 We found #plastics, #mercury, & #PFAS over time, bw life stages. Plstc ingestion diff. bw juvs & adults. Plstcs bw 4-10 mm, mostly polyethylene. Plstc freq higher than prev estimates. THg stable over time. PFAS in 8 tissues and appear to impact liver lipids.
