Ocean Heat: In the new Arctic summer ice regime, with extended open water periods in areas previously covered with sea ice, ocean heat, received during these summer ice-free periods, may be either confined to the surface mixed layer or enter deeper ocean waters. Our goal is to determine the amount and disposition of ocean heat received and determine whether it is exhausted during fall freeze-up and affects only initial ice growth or, remains in the ocean and has residual effects on ice growth during winter and spring. Sea State Regime: Large expanses of ice-free water in the Chukchi Sea in the late summer have potentially changed the impact of fall storms by creating wave fields in the vicinity of the advancing ice edge. A goal is to determine if larger amounts of frazil ice and increased turbulence levels in the water column result, leading to significant increases in pancake ice formation and higher incorporation of sediment into pack ice in the continental shelf regions.
