Mapping northern Greenland waters Hydro International

Understanding the interplay between glaciers and the ocean poses is needed to improve projections of future sea-level rise and the potential impact on hundreds of millions of coastal residents. Seafloor mapping is critical in this pursuit, particularly where the ice sheets of Greenland and Antarctica meet the ocean. Northern Greenland’s marine realm remains one of Earth's least explored, with completely uncharted fjords. In 2019, one of these fjords, where Ryder Glacier drains, was finally mapped using the Swedish icebreaker Oden, providing critical new information on the processes responsible for the rapid melting of the Greenland Ice Sheet. In 2024, the next unmapped fjord to the east is the target; the Victoria Fjord where CH Ostenfeld Glacier drains. Grant no. NA20NOS4000196
