Continuing Analysis for NORSE and TFO
Abstract
Here we request funds to support continuing, intertwined analysis as part of the NORSE and TFO programs. The analysis described here most broadly represents an attempt to understand the processes that set upper ocean stratification and sound speed, and how those processes are affected by atmospheric forcing. In the NORSE experiment, as in the locations of many recent ONR experiments, subduction and stirring of water masses with very different temperature and salinity values leads to significant variability on a range of vertical and horizontal scales of both sound speed and spice. The NORSE experiment is a particularly good example of such processes. In the Jan Mayen area, a large front between warm-salty Gulf Stream origin water is adjacent to cooler-fresher Arctic influenced water. A key component of both NORSE and TFO is to build tangible bridges between physical oceanography and acoustic analysis. Small-scale sound speed variability from fronts, submesoscale eddies, and spice variability strongly affects the acoustic propagation through the upper ocean. Ongoing analysis both for NORSE and considering a wider array of global datasets as part of TFO, aims to get at the heart of this cross-disciplinary intersection.This abstract is publicly releasable.
