The organic carbon flux to Arctic margin sediments: redox tracers stable isotopes and biomarkers as proxies for change
To date, sediment cores have been successfully collected, while aboard the CCGS Sir Wilfrid Laurier in July 2007, and the CCGS Louis S. St. Laurent in July, 2009. The suite of cores spans the continental shelf and slope at depths varying from 60 to 2000 m from the Bering and Chukchi Seas, to Barrow...

To date, sediment cores have been successfully collected, while aboard the CCGS Sir Wilfrid Laurier in July 2007, and the CCGS Louis S. St. Laurent in July, 2009.

The analysis of the samples is now completed and we are now working on the interpretation of results. There is a lot that can be learned from the sediment cores.
