Arctic sea-ice extent and volume are declining rapidly, and according to model simulations, the Arctic Ocean may become seasonally ice-free as early as around 2040. As sea ice is a critical component of the Earth system, for the prediction of future climatic processes and related environmental changes, it is crucial to forecast its evolution.
However, despite the extreme societal and environmental relevance, our understanding of natural sea-ice variability and its response to external natural and human-induced forcing is associated with significant uncertainties. Consequently, state-of-the-art climate models still show a very large spread in the prediction of climate responses for the next century, especially at high latitudes. The insufficient knowledge about natural sea-ice states makes it essential to develop high-resolution sea-ice reconstructions extending back in time beyond the instrumental and satellite era.
The overall purpose of the project is therefore to establish longer time-series of sea-ice variability off NE Greenland and its linkages with ocean circulation, Greenland ice-sheet dynamics, external forcing and global climate.
The outcome of the study will significantly improve our basic understanding of processes determining sea-ice cover, which is needed for a better prediction of the future changes of Arctic sea ice.
