Ammassalik Basin Sampling 2012

Edited by Stephane Polteau, S. Planke, and R. Myklebust


The ABS12 survey is located in a frontier area for oil and gas exploration offshore SE Greenland. A total of 21.75 m of sediments were recovered from nine coring sites. Most sites showed evidence of seepage of hydrocarbons, with strong oil smell at the bottom of the sections. Results from the cruise strongly suggest that Jurassic oil is actively seeping to the seafloor from a shallow and uplifted Jurassic reservoir.

The ABS12 report is integrated in the "North Atlantic Margin Sampling 2018" project (NAMS18) currently in progress.
