Changes to the ADCPs were logged and DAP were informed when multibeam bathymetry was considered a scientific priority. The OS75 was switched off for significant parts of the voyage, especially around Christmas and Cocos (Keeling) Islands while shallow water mapping was being undertaken.\nThroughout the voyage there were high counts of low-quality position data from Seapath. In collaboration with UHDAS Support, on the 2022-10-10 the ADCP was configured to use POSMV rather than Seapath for position and heading data, consequently the data has been split into two parts.\nADCP 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 here: https://currents.soest.hawaii.edu/docs/adcp_doc.\nBoth the RDI Ocean Surveyor 150kHz ADCP and the RDI Ocean Surveyor 75kHz ADCP were run in narrowband mode. The OS150 ADCP was used throughout the voyage. The OS75 was used in deep waters and turned off in shallower waters so as not to interfere with the EM710\nInternal triggering was used. The drop keel was at 8 m below the waterline for the duration of the voyage. See the voyage computing and electronics report for more details regarding data acquisition.\nThis dataset was processed (quality-controlled), and then archived by the CSIRO National Collections and Marine Infrastructure (NCMI) Information and Data Centre (IDC).", "num_resources": 10, "num_tags": 0, "organization": {"id": "c0017ec2-e0d5-4e64-9238-27110ef01b78", "name":
