LANGRANGIAN CURRENT MEASUREMENTS AND LARGE-SCALE LONG-TERM DISPERSION RATES (SOFAR FLOAT EXPERIMENT)
Activity entering the water from a deep sea disposal of radioactive waste package will be dispersed through the ocean both by the long-term circulation pattern and the eddy (mixing) motions. Sofar floats are thought to be the most cost effective way of obtaining direct information on the circulation over a few years and the only way to obtain information, in the Lagrangian framework, on the statistics of the eddy movements. The Sofar float experiment seeks to answer questions including (a) what is the magnitude of space and time variability of the horizontal eddy kinetic energy in the eastern basin and is it consistent with that found in the western basin of the Northern Atlantic? (b) is the deep flow inferred from incoherent arrays of moored current meters correct? The report covers the preparation stage for the Sofar float experiment which takes place from autumn 1984 to 1986. It describes the recent results from the western North Atlantic, the design of the new deep Sofar float, the testing of the float including the range at which these new floats can be heard, the experimental design and expected results.
