Description
Summary:The aim of this study is to paint a picture of the evolution of the horizontally variable ice-ocean boundary layer throughout summer. Observations were made during the drifting Surface HEat Balance of the Arctic (SHEBA) experiment in the summer of 1998, The ice-ocean boundary layer near leads is studied with an Autonomous Underwater Vehicle (AUV) and a novel technique to use vehicle motion data to calculate turbulent vertical water velocity along the vehicle path. Vertical fluxes are obtained and extend from the energy-containing wave number range and continue into the inertial subrange. This study is the first to measure horizontal profiles of turbulent fluxes in the ice-ocean boundary layer. AUV data are used in conjunction with: fixed-mast turbulent fluxes at discrete levels in the boundary layer, Conductivity-Temperature-Depth data (vertical casts and lead surveys), and a suite of measurements made by other investigators. 1+ %A%+ +%%+ ,,%A +%% %.%% The original document contains color images.
