DS3F Workshop “Fluid flow in Arctic continental margins and ocean ridges” May 30-31, 2011, Tromsø, Norway.

One of the primary goals of this workshop is to develop a science report for conducting scientific drilling into fluid escape pathways in Arctic continental margins and (sedimented) ocean ridges, and to develop synergies with national and international ocean observatory programs. Drilling into fluid release areas of the Arctic has never been done before, but it is of regional and global relevance providing opportunities for fundamental, forefront interdisciplinary research involving geophysics and geology, geochemistry, biogeochemistry, microbiology and biology.

New discoveries at the seabed and beneath show vigorous methane venting from gas chimneys. Understanding past and present fluid leakage, associated geological and biological processes and the effects of climate change on the Arctic seabed region in general, and on the stability of gas hydrate and release of geofluids in particular, is therefore both a scientific challenge and of high societal relevance. Drilling into selected fluid-escape chimneys will increase our understanding in climate, environmental, energy and ecosystem research. However, such a drilling campaign has yet to be developed.
