An understanding of the interplay between glaciers and the ocean is needed to improve sea-level rise projections. 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 areas, with completely uncharted fjords. In 2019, one of these fjords was mapped by the Swedish icebreaker Oden, with the next unmapped fjord to the east the target for 2024.

How marine-terminating glaciers impact global sea-level rise

The large ice sheets on Greenland and Antarctica consist of merged glaciers that drain areas of the ice sheets into the ocean through ice streams, similar to how rivers

Hydrography is reaching a point at which standing still is no longer an option. The latest industry survey reveals a sector balancing rising data volumes, shifting skill demands and rapid advances in automation, AI and remote sensing. Organizations are working to secure certified personnel, keep pace with modern equipment and deliver high-quality data, despite mounting operational pressure. What emerges is a field that is adapting – but not without friction. Across all responses, one theme resonates: the future is arriving faster than expected. The question is whether the sector will shape that future, or be shaped by it.
