The physical mechanisms that cause the large scale, long term                   glacial cycles found in the geologic record are not well                        understood.  In this research project a hierarchy of climate                    models will be used to investigate the relative importance of                   some of the physical mechanisms that contribute to shaping                      climate on the 10,000 to 100,000 year time scale.  The scientific               investigations to be conducted include 1) an examination of the                 influence of sea ice and leads on both polar and global climate,                especially with respect to their impact on the energy and                       moisture exchanges between the atmosphere and ocean; 2) an                      examination of the impact of orbital variation induced solar                    radiation variations on climate as modeled by the coupled sea ice               - climate model, and of the physical mechanisms that facilitate                 those climate changes; and 3) an investigation into the processes               involved in ice sheet initiation.  This work is important because               it will enhance our understanding of the complex role of sea ice                related processes in in affecting long term climate change.
