1/4 Hi all! Welcome to my #WSTC6 #ContSesh2 thread!
The Gulf of Maine 🌊 (GoM) is grappling w/ huge changes due to ⬆️ human influences 🌡️.
We use Great Shearwaters (GRSH) as sentinels of the GoM to answer ?s abt pollutant occurrence & trends & how they may be impacting GRSH

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.
1. #WSTC6 #FishSesh Purse seine fishing is an emerging arena for seabird #bycatch. However, these are also impacting seabirds with edible #fish oil. #Soaked individuals are disrupted in waterproofing, thermal isolation, flight, and prone to #death. How does this happen? 
2. #WSTC6 #FishSesh #Chile #shearwaters #albatrosses #gulls are affected by fish oil from the direct discharge of #wastewaters or individuals #trapped in the purse seine gear (mean N°ind./set 8.41-12.90 CI 95%, with 96.87% of all trapped soaked)
