International audience The Vestnesa Ridge is a NW-SE trending, ~100 km-long, 1-2 km-thick contourite sediment section located in the Arctic Ocean, west of Svalbard, at 79°N. Pockmarks align along the ridge summit at water depths of ~1200 m; they are ~700 m in diameter and ~10 m deep relative to the...
