AUV-Based Measurements of the Oregon Coastal Ocean

Description
Summary:Our long-term goals are to understand the mechanisms of turbulence and mixing in the coastal ocean environment sufficiently well to be able to incorporate mixing processes in coastal circulation models as sub-grid scale parameterizations. We specifically target turbulent mixing in heretofore difficult to sample areas related to significant features of the coastal circulation. Our investigation includes processes affecting the surface boundary, upwelling front, buoyant plumes, and biological thin layers. We plan to address this objective by conducting measurements to concurrently resolve microscale, finescale, and mesoscale variability of various oceanic variables from sensors mounted on an autonomous underwater vehicle (AUV) along with other available and appropriate shipboard technology.
