Abstract:

The long-term goal of this program is to understand the physics of small-scale oceanic processes including internal waves, hydraulics, turbulence and microstructure that act to perturb and control the circulation in coastal oceans and, in doing so, affect the propagation of sound and light. Ongoing studies within the Ocean Mixing Group at OSU emphasize observations, interaction with turbulence modelers and an aggressive program of sensor instrumentation development and integration. The objective of this proposal is to construct a rugged, high-resolution pressure pod that can be launched from an aircraft. This will sink to the seafloor for periods up to 3 months. An acoustic release will permit recovery and surface reporting of all data. We have modified existing electronics hardware to count Paroscientific pressure and temperature frequencies and to integrate GPS receiver and Iridium and wireless transceivers. We are in the process of adapting a release acoustic transducer into the end cap of the Ppod. This will undergo extensive testing at the lab in OctoberNovember 2009 and in Puget Sound in December 2009.
