Baseline hydrocarbons in Baffin Bay sediments, 2008-2009 (NGMP ID EC13)
Sediment cores were collected by box coring at eleven locations in northern Baffin Bay (including the North Water Polynya, Lancaster Sound, Scott Inlet, and Gibbs Fjord) during the ArcticNet 2008 and 2009 cruises. Plexiglass tubes (10 cm diameter) were pushed into the sediments; cores were between 1...
