ONR grant N00014-98-1-0037, "Arctic Mixed Layer Dynamics," is the last in a series of Arctic Mixed Layer Grants extending over more than 20 years. Throughout that time our approach has been to bring new tools to bear on fundamental questions about mixing in the upper ocean, particularly the mixed layer and underice planetary boundary layer. Over the years we have sought to understand the heat and mass balance of the mixed layer, marginal ice zone processes, the Arctic internal wave and mixing environment, summer and winter leads, and convection. In light of recent changes In the upper ocean structure, our long-term goals shifted toward processes important to large-scale changes. Our primary objective under the present grant was to understand the effect of horizontal inhomogeneity on the surface boundary layer during summer.
