This record describes the Acoustic Doppler Current Profiler (ADCP) data collected from the Marine National Facility RV Investigator voyage IN2022_V07, titled: "HALO - Halimeda bioherm Origins, function and fate in the northern Great Barrier Reef." The voyage took place between August 15, 2022 and September 7, 2022 (AEST), departing from Brisbane and returning to Cairns.
The RDI Ocean Surveyor 150kHz ADCP was run in narrowband mode at the start of the voyage and thereafter in broadband mode, the RDI Ocean Surveyor 75kHz ADCP was run in narrowband mode only. There is no data for the OS75 for the first part of the voyage.
Internal triggering was used.
Both drop keels lowered to flush with gondola (approx 8m below waterline) to reduce interfer-ence with EM2040 system. See the voyage computing and electronics report for more 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).
