This project maintains the Acoustic Doppler Current Profiler (ADCP) computer system on the RV/IB Nathaniel B. Palmer (NBP) and ARSV Laurence M. Gould (LMG). These computer systems are used to manage and post-process data from the ADCP sonars on the NBP and the LMG. On the LMG, the ADCP data is specifically collected and managed under the Chereskin (O-317-L) project, but is available to all cruise participants. On the NBP, the systems are maintained for general grantee requests.

Field Season Overview

Testing of the systems is completed during once a year during a scheduled port call. During these maintenance port calls, the system is tested extensively requiring the ability to actively ping the sonars in port to ensure proper system function.Testing these systems requires activating the sonars at the pier for four or five cycles of up to ten minutes each. An Exclusive Economic Zone (EEZ) permit is not required for this.
