RV Investigator Voyage IN2022_V05 ADCP Data

This record describes the Acoustic Doppler Current Profiler (ADCP) data collected from the Marine National Facility RV Investigator voyage IN2022_V05 titled "The tsunamigenic submarine landslides and deep-marine canyons of Australia’s Tasman Sea margin: Causes and Consequences." The voyage took place between May 28, 2022 and July 3, 2022 (AEST), departing from Hobart and returning to Brisbane.

The ADCPs ran well throughout the voyage. OS75 and/or OS150 ADCPs were intermittently isolated to reduce interference with multibeam systems as required.

As required GSM were turning off one or both of the ADCPs, generally in less than 500m depths, to avoid the significant acoustic interference this generates (particularly between the OS75 and EM710). Changes to the ADCPs were logged and DAP informed with multibeam bathymetry generally being the scientific priority.

Data was collected using UHDAS and post-processed using CODAS. Both the RDI Ocean Surveyor 150kHz ADCP and the RDI Ocean Surveyor 75kHz ADCP were run in narrowband. Internal triggering was used. The drop keel was set at 7m below the waterline for the duration of the voyage.
Please refer to the voyage Computing and Instrumentation reports for further details regarding data acquisition.

This dataset was processed (quality-controlled), and then archived by the CSIRO National Collections and Marine Infrastructure (NCMI) Information and Data Centre (IDC).
