Icebergs influence the seafloor

Icebergs influence the oceans and can dig into the seafloor at depths limited by their keel depth, thus representing a danger for underwater infrastructures. A team including Daniel Bourgault, professor at UQAR-ISMER, provides evidence that icebergs can also affect the seafloor beyond their keel depth and cause underwater landslides. These results suggest that icebergs originating from the Arctic, Greenland, and Antarctica can pose hazards thousands of kilometers from their original source and are an additional source of marine geohazards. The article appeared in the journal Nature Geoscience.

Alexandre Normandeau, researcher at the Geological Survey of Canada and the first author of the paper, came to talk about it during a Québec-Océan webinar (in french).
