Registration for UK teachers is now open! Registration for US teachers has ended and the US event is full. (as of Nov 6, 2019)

Sampling bedrock beneath the ice sheet, GHC will identify if and when the glacier retreated in the past, how it recovered, and how it is currently responding to environmental conditions.

Investigating sediments deposited in the seas near the glacier, Thwaites Offshore Research (THOR) will reconstruct past changes in environmental conditions and the glacier’s response to these, thereby adding context to our projections of future change.

Measuring ocean circulation and thinning beneath the floating part of the glacier using state of the art technology such as AUVs and automated land-ice stations, TARSAN will investigate how the ocean and atmosphere are affecting the glacier.
