Our objective is to help communities prepare for climate risks emerging from East Antarctica and the Southern Ocean. We will do this by integrating knowledge of the region’s ocean, atmosphere, cryosphere, and ecosystems.

Denman
Marine
Voyage

The Denman Marine Voyage (DMV) will take more than 60 scientists to the Denman Glacier region for two months in late February, 2025

Science and technical teams will work closely with the ship’s crew across 24-hour shifts and use a range of methods - including bathymetry (sea floor mapping), rock and sediment sampling, sea-glider and mooring deployments, seal tagging and physical and chemical oceanography - to learn more about the factors influencing the glacier’s melt rate and its possible contribution to higher sea levels in future
