RV Investigator Voyage IN2019_V06 ADCP Data

This record describes the Acoustic Doppler Current Profiler (ADCP) data collected from the Marine National Facility RV Investigator voyage IN2019_V06, titled: "Tropical observations of atmospheric convection, biogenic emissions, ocean mixing, and processes generating intraseasonal SST variability." The voyage took place from Darwin (NT) to Darwin between October 19 and December 17, 2019.Data was collected during in2019_v06 for the duration of the voyage. Data was collected using UHDAS and post-processed using CODAS.The voyage consisted of two legs, with a port visit on 11 November 2019. The ADCP data for both legs have been processed as one dataset. Leg 1 was 19 October to 11 November 2019, Leg 2 from 11 November to 17 December 2019.The RDI Ocean Surveyor 150kHz ADCP was run in both narrowband and broadband for various sections of the voyage. The RDI Ocean Surveyor 75kHz ADCP was run in narrowband for a section of the voyage. Both transducers were switched off during the port period on 19 October. Both transducers were switched off from 00:45 to 02:07 UTC on 9 October.Internal triggering was used.The drop keel was at 4m extension (10.54m below centre of reference) for leg 1 and 1.19m extension (flush with gondola, 7.93m below centre of reference) for leg 2.The bin sizes for the 150kHz ADCP were changed at various times throughout the voyage to obtain finer data granularity when the depth was shallow.See the voyage computing and electronics reports 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.
