Project information
Project aim
In-situ observations of sea-ice drift from the Arctic and Antarctic together with auxiliary remotely-sensed data will be used to determine the contribution of sub-daily motion on the overall drift. Because of the cyclical characteristic
of sub-daily motion it induces repeated opening and closing of the ice pack, which has been shown to increase the net ice-growth rate. The net ice growth and the overall sea-ice volume are crucial parameters in understanding the ocean-ice-atmosphere system, especially in the light of climate change. The role of this high-frequency motion in modifying sea-ice thickness and volume will be derived.

Information of sea-ice drift is crucial to understand the East Antarctic climate system, and knowledge of sea-ice dynamics is needed to fully explore the effects of cryospheric changes on the ecosystems within the Antarctic pack-ice zone. Satellite-derived sea-ice data cover the Southern Ocean.

Category 3: Abstract
Sea-ice drift and deformation in the Western Weddell Sea during austra; summer of 2004 are characterised using in situ data from a meso-scale array of 24 drifting ice buoys. About 30 days of data during late November and December 2004 are available from the buoy array.
