Shipboard Surveys of the Upper Ocean Velocity and Thermohaline Structure During the COARE Intensive Observation Period

Project Summary

As part of the Intensive Observation Period (IOP; November 1992-February 1993) of the TOGA Coupled Ocean-Atmosphere Response Experiment (COARE), four 27-day research cruises were conducted within the climatically important western Pacific warm pool. Underway, high-resolution, upper-ocean velocity and thermohaline observations were made over a 200-km domain containing the IOP moored array. The measurements were made with a towed profiling CTD (Seasoar), acoustic Doppler current profiler (ADCP), and a bow staff and towed catamaran. High quality shipboard meteorological observations were made concurrently to provide estimates of air-sea fluxes. The data are being analyzed to understand the response of the upper ocean to a rich variety of atmospheric forcing: intermittent heavy rain, strong diurnal heating, squalls, and westerly wind bursts. The high-resolution vertical sections (down to 300m) of temperature, salinity and velocity provide the spatial context for the interpretation of microstructure and moored measurements made at fixed locations within the IOP. The analysis will ultimately contribute to improved coupled models of the tropical atmosphere and ocean.
