Not listed THIS PROPOSAL ASPIRES TO QUANTIFY AND CHARACTERIZE THE ROLE OF SUBMESOSCALE FEATURES IN THE ARCTIC UPPER OCEAN HEAT BUDGET PARTICULARLY THEIR INFLUENCE ON THE MELT AND FORMATION OF SEA ICE. ARCTIC SEA ICE EXTENT HAS DECLINED MORE QUICKLY THAN SIMULATIONS AND PROJECTIONS OF COUPLED ICE-OCEAN MODELS PREDICT. THIS DIFFERENCE IS ATTRIBUTED TO PHYSICAL PROCESS THAT ARE UNRESOLVED OR MISSING IN THESE LARGE SCALE MODELS WITH THE ADVECTION AND MIXING OF HEAT IN THE UPPER OCEAN BEING A STRONG CANDIDATE. USING INNOVATIVE IN SITU OBSERVATIONS AND NASA SATELLITE MEASUREMENTS I WILL INVESTIGATE THE RELATIONSHIP BETWEEN SATELLITE-OBSERVED SURFACE FRONTS ICE EXTENT AND THE RESULTING MODULATION OF VERTICAL HEAT FLUXES BY SUBMESOSCALE PROCESSES. SPECTRAL ANALYSIS WILL ILLUMINATE THE MOST ENERGETIC SCALES OF SATELLITE AND IN SITU OBSERVATIONS WHILE STATISTICAL RELATIONSHIPS BETWEEN LATERAL GRADIENTS AND VERTICAL MIXING WILL CHARACTERIZE THE INTERACTIONS OF THE VERTICAL AND LATERAL GRADIENTS. FINALLY I WILL TEST THE VALIDITY OF AN EXISTING SUBMESOSCALE PARAMETERIZATION USING THESE OBSERVATIONS MODIFYING THE PARAMETERIZATION FOR ARCTIC OCEAN CONDITIONS IF NEEDED. QUANTIFYING THE INFLUENCE OF SUBMESOSCALE FEATURES ON THE MELT AND FORMATION OF SEA ICE IS CRITICAL IF WE ARE TO PARAMETERIZE THE EFFECT IN SEA ICE SIMULATIONS AND PROJECTIONS.
