OCEAN TURBULENCE ESTIMATES IN THE COASTAL OCEAN MODELING AND OBSERVATION PROGRAM (COMOP) STUDIES AT LEO-15.
 
In the context of the COMOP network, microstructure data have been obtained from a small REMUS AUV instrumented with a comprehensive suite of turbulence sensors. Instrumentation included shear probes and an ultra-fast thermistor, two CTDs, an upward and downward looking ADCP, and an ADV-O. This data acquisition enables estimates of dissipation rate, kinetic energy, vertical shear of horizontal velocity, and stratification. These estimates are utilized to characterize subgrid scale processes in the SCRUM model, and compare turbulence closure approaches. During July 1998, a field experiment was conducted in the LEO-15 region off New Jersey, to examine mixing processes associated with wind-driven upwelling. Using model-based adaptive sampling, the AUV was deployed along a trajectory through components of the local upwelling region, including the upwelling gyre and offshore jet. The character of the microstructure is discussed in terms of the larger scale structures in the synoptic observations and model predictions.
