Objetivo
A radical change occurred a decade ago in Arctic atmospheric circulation. Associated with a reversal of the Arctic Oscillation (AO). This resulted in changes of sea ice motion and characteristics, most manifest in the critical region north of Greenland. GreenICE takes advantage of winter ice camps in this region. Seabed sediment cores will map the climatic record, and a multilevel study of sea ice - in situ thickness and roughness measurements; buoys for ice dynamics, and satellite coverage - will be performed. An existing sea ice model will be improved and used to extend regional results to basin scales. The aim is to form a complete picture of ice response to an AO reversal, matching this to concurrent climate change. By reference to the regional climatic record for the past 2000+ years, we thus aim to understand the nature and magnitude of Arctic sea ice response to observed climate variability.
