RIEP projects supported in FY08
Dr. Dave Hebert Cross-frontal Exchange South of Rhode Island. In late October 2007, Drs. Dave Hebert, Mark Prater, and David Ullman of the URI Graduate School of Oceanography conducted a series of high-resolution CTD measurements across the shelfbreak front approximately 90 miles south of Rhode Island. Using the URI ScanFish CTD and shipboard ADCP, surveys were conducted around subsurface Lagrangian floats. Hebert, Prater, and Ullman sought to map the development of a meander in the shelfbreak jet, a process thought to contribute significantly to cross-frontal exchange. This data and that collected during EN 400, another RIEP supported cruise, will be used for a proposal to be submitted to NSF.
In addition, a short test of the acoustic receiver on a new RAFOS
float developed at URI with NSF support was conducted. Preliminary
analysis has shown that the floats can detect the acoustic signals
from more than 10 km away using a simple underwater speaker. We plan
to use this information in our proposed work to NSF to develop a
high-resolution coastal acoustic navigation system for gliders and
other autonomous platforms.
