This record describes gravity data collected on RV Investigator voyage IN2022_V08, titled "Biodiversity Assessment of Australia’s Indian Ocean Territories", which departed Darwin on September 30 and returned to Fremantle on November 3, 2022. This was a continuation of voyage IN2021_v04. The gravity meter instrument is a MicroG Lacoste Air-Sea II. Data are stored in .ENV and .DAT data files at CSIRO. There are 36 files totalling 576 MB of raw data in this dataset. A wharf tie was undertaken at the end of the voyage at Henderson Wharf (in Fremantle) upon vessel arrival using a Scintrex Autograv CG-5. No wharf could be undertaken in Darwin due to personnel restrictions. Note: Due to a Time Server issue on the Gravity PC, data from Julian days 273-297 (i.e. 30th September to 24th October 2022) had to be time corrected, and those files can be found in the "time_corrected" folder which is stored with the raw data.
Wharf tie data can be found in "Henderson_wharf_tie_2022_11_03.TXT", which is stored with the raw data. No processing has been conducted on this data. Additional information regarding this dataset is contained in the GSM data acquisition and processing report.
