The year 2007 has witnessed yet another record minimum sea ice extent in the Arctic. Some climate models now predict that summer Arctic sea ice might altogether disappear in about 30 or 40 years. While the effects of a shrinking sea ice cover on global climate, ocean circulation and marine biology are expected to be quite significant, they are very difficult to evaluate because of our incomplete understanding of the polar climate components and our limited ability to model them. Coupled sea ice-ocean models are key for organising our current knowledge of the physical and biogeochemical properties of sea ice and ocean, exploring poorly understood processes, and forecasting future changes and their impact on the natural world and human activities, such as the exploitation of gas, oil and mineral resources, navigation, tourism, and military operations.
How realistic are current sea ice-ocean models? The representations of which processes and properties need to be introduced or revised in order to improve the performance of these models? How reliable are these models for operational, medium-range, and climate forecast? In this session, we invite contributions regarding all aspects of sea ice and sea ice-ocean modelling. Presentations and posters on modelling of snow and ice thermodynamics and dynamics, ice-atmosphere and ice-ocean interactions, ice biological and chemical processes, and data assimilation in sea-ice models will be welcome.
