Abstract:

Sharp vertical temperature fronts and complex temperature inversions observed in the Chukchi Sea during MIZPAC 77 were investigated in a further effort to define the mechanisms for the formation of finestructure. An association was found between the upper level current directions inferred from the gross ice edge recession rates and the occurrence of fronts and finestructure. Currents with a strong directional component normal to the ice edge were associated with extensive finestructure and those with a weak component were associated with sharp fronts but little or no finestructure. Six closely spaced crossings of the Alaskan Coastal Current made it possible to describe the circulation in greater detail than was previously possible. A peculiar ice bay was discovered off Point Barrow in which there was extensive finestructure, including some which was deeper than any previously observed. Author
