Preliminary Scientific Assessment of the July 2004 SEPTR Test Deployment

Abstract

Initial results are presented from a July through September 2004 test deployment done with a modified, preliminary version of SEPTR (circa 2003). The SEPTR performed well overall, returning twice-daily vertical profiles of temperature and salinity, in addition to nearly continuous profiles of velocity. However, a number of problems requiring attention were identified. These include an intermitent failure of the battery charger, which caused the profiler to stay near the surface for extended periods of time, periods in which no data were transmitted, premature shutdown of the ADCP, problems with the wave-measurement system, and sensor response differences which led to unrealistic salinity spikes. It is hoped that results from this test deployment will help identify problems and improve performance during further development of SEPTR through a Cooperative Agreement betwen the Naval Research Laboratory and NATO Undersea Research Centre.
