RV Investigator Voyage IN2018_V03 ADCP Data

This record describes the Acoustic Doppler Current Profiler (ADCP) data collected from the Marine National Facility RV Investigator voyage IN2018_V03, titled: "Integrated Marine Observing System: monitoring of East Australian Current property transports at 27oS." The voyage took place between April 19 and May 10, 2018 departing Brisbane (QLD) and returning to Brisbane.

Data was collected during in2018_v03 for the entire voyage. Data was collected using UHDAS and post-processed using CODAS. The os150(150kHz) ADCP was not operational during this voyage and was replaced with a wh150(150kHZ). The wh150 was calibrated in the preceding transit. The 75khz ADCP was operated in narrowband mode with 8m bins for the duration of the voyage. Internal triggering was used as external triggering was found to be unstable on previous voyages. The drop keel was at 4m for most of the voyage but raised to 2m during periods of rough weather. Acquisition was stopped and started upon a keel depth change to ensure no data was corrupted. See the voyage computing and electronics report for more details regarding data acquisition.

This dataset was processed and then archived within the CSIRO Oceans and Atmosphere (O&A) Information and Data Centre (IDC) in Hobart.
