Abstract:

The reduction of the sea ice coverage during the boreal summer will lead to an increased importance of wind waves for the dynamic processes of the Arctic Seas. The large ice free areas lead to longer fetch and thus longer and higher sea state. Wind waves will enhance upper-ocean mixing, may affect the breakup of ice sheets, and will likely lead to increased coastal erosion. The primary long-term goal is a better understanding of the two-way interaction of waves and sea-ice, in order to improve wave models as well as ice models applicable to a changing Arctic wave and ice climate. This includes observation and information retrieval from various data sources, in particular from spaceborne SAR imagery. Such retrieval methods of sea state in the MIZ will complement and validate modelling data for the spatial and temporal evolution of sea state in the MIZ. Further goals are the development of near-real time wave field observations and their delivery to marine operations in the Arctic.
