This project consists of the maintenance of Acoustic Doppler Current Profiler (ADCP) computer systems on the ARSV Laurence M. Gould (LMG) and RVIB Nathaniel B. Palmer (NBP). Port calls are required every one to two years to service these systems. Typically, this consists of upgrading or re-installing the UHDAS software on the shipboard data processing computers. Occasionally this will require hardware upgrades that require pre-approval by NSF to ensure the costs are covered by the grant. These computers are used to manage and post-process data. On the LMG, the ADCP data is specifically collected and managed under the Chereskin (O-317-L) project. On the NBP, the systems are maintained for general grantee requests.

Field Season Overview

This project will provide software and support for the ADCP computer systems on the LMG and NBP. Approximate biennial upgrades will occur during scheduled port calls. During these maintenance port calls, the system is tested extensively, which requires the ability to active 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 10 minutes each. They expect to visit the LMG soon after it comes out of drydock, to be able to visit both LMG and Palmer on the same trip.
