Robots in the Arctic: An autonomous adventure to Greenland’s outlet glaciers

EGU Cryospheric Sciences Division | 8 October, 2026

Research cruises are a fundamental part of the cryospheric sciences. As the Arctic warms, the systems that shape our world look much different from one season to the next, making it more critical than ever to measure the changes of our icy world. Here, three early-career researchers share insights from a cruise they took part of this summer aboard the RRS Sir David Attenborough as part of a British Antarctic Survey campaign.

The giant seafloor sponge: how water ends up in subducting crust

EGU Geodynamics Division | 7 October, 2026

"Subduction" is a process that occurs when two tectonic plates collide with each other. As long as one of the plates is an "oceanic plate", then the denser of the two tectonic plates will be pushed under the less dense plate and subduction will occur. This phenomenon occurs all over the world, with the total length of subduction spanning more than 55,000 km. Apart from being a primary driver of plate tectonics, an important reason to study subduction zones is that they are the locus for some of the most devastating geologic hazards on Earth. Subduction zones produce the largest magnitude earthquakes on the planet and they lead to consistent volcanic activity on the plate that lies above the sinking plate. One important consideration for understanding these geologic hazards is how water influences their evolution.
