Acquisition, Processing and Monitoring of ADCP Ocean Current data
in the U.S. Academic Research Fleet 

Ocean currents derived from ADCP (Acoustic Doppler Current Profiler)
measurements are used by many oceanographers.  The fundamental
components of the ADCP system are the instrument itself, ship's
heading, and position.  University of Hawaii had been involved
for over 20 years in developing, maintaining, and supporting robust, 
configurable, open source software to process ADCP data. This 
processing sofware, "CODAS" (Common Ocean Data Access System), is 
the core of a larger effort to create a reliable and robust system
to acquire and process ADCP data autonomously, on board ships. 

This talk will give an overview of the acquisition, processing, 
and monitoring capabilities of this system "UHDAS", and what 
a scientist at sea can expect from a UHDAS system.  This system
has been installed on over 20 U.S. research ships, and is expected 
to be running on the Pt Sur in late January 2012.
