This record describes gravity data collected on RV Investigator voyage IN2019_V04, 'Hotspot dynamics in the Coral Sea: connections between the Australian plate and deep Earth' which departed Cairns on the 7th August 2019 and returned to Brisbane on the 3rd September 2019. The gravity meter instrument is a MicroG Lacoste Air-Sea II and was run continuously during the voyage in the Coral Sea, within the EEZ of Australia, Papua New Guinea, Solomon Islands and New Caledonia. Data are stored in .ENV and .DAT data files at CSIRO. There are 57 files totalling 463 MB of raw data in this dataset. Wharf ties were undertaken at the start and end of the voyage using a Scintrex Autograv CG-5. Reference station number 2008909952 was used in Cairns (located at Cairns airport) and station number 2016909147 was used in Brisbane (located at Northshore Riverside Park). Wharf tie data can be found in "Cairns_wharf_gravity_tie_in2019_v04.TXT" and "Brisbane_wharf_gravity_tie_post_in2019_v04.TXT", which are stored with the raw data folder. No processing has been conducted on this data. Additional information regarding this dataset is contained in the GSM data acquisition and processing report.
