RV Investigator Voyage IN2022_V09 ADCP Data

This record describes the Acoustic Doppler Current Profiler (ADCP) data collected from the Marine National Facility RV Investigator voyage IN2022_V09, titled: "Valuing Australia’s new Gascoyne Marine Park." The voyage took place between November 19, 2022 and December 19, 2022 (AEST), departing from Fremantle and returning to Fremantle. The ADCP was run for a notable part of the voyage, though it was turned off occasionally to avoid creating interference with the sounders and USBL. ADCP data were collected using the University of Hawaii Data Acquisition System (UHDAS) and post-processed using the Common Ocean Data Access System (CODAS). Documentation for these systems can be found in (Hummon, 2009-2021).Both the RDI Ocean Surveyor 150kHz ADCP and the RDI Ocean Surveyor 75kHz ADCP were run in narrowband mode.Internal triggering was used.The drop keel was set at 1.19m below the waterline for the duration of the voyage.Apart from the gap in the data, due to ADCP being turned on/off, and the usually required quality control data cleaning there were no significant ADCP processing-related issues encountered.
