Study of Environmental Arctic Change (SEARCH) and Developing Arctic Modelling and Observing Capabilities for Long-term Environmental Studies (DAMOCLES)

May 10, 2008 - The SEARCH Sea Ice Outlook is an international effort to provide an integrated, community-wide summary of the state of arctic sea ice over the 2008 summer season. The Sea Ice Outlook produces monthly reports based on an open and inclusive process that synthesizes input from a broad range of scientific perspectives.

The intent is not to issue predictions, but rather to summarize all available information from ongoing observing and modeling efforts to provide the scientific community, stakeholders, and the public the best available information on the evolution of the arctic sea ice cover.
