This record describes gravity data collected on RV Investigator voyage IN2023_V05, titled "Untangling the causes of change over 25 years in the southeast marine ecosystem (Voyage 1). The voyage took place between June 28, 2023 and July 30, 2023 (AEST), departing from Hobart and returning to Hobart.

The gravity meter instrument is a MicroG Lacoste Air-Sea II. Data are stored in .ENV and .DAT data files at CSIRO. There are 14 files totalling 205 MB of raw data in this dataset. A wharf tie was not undertaken due to the sensor replacements, and malfunctions.

Gravity data was acquired for adhoc periods throughout the voyage although due to continued errors, malfunctions and swapping of sensor hardware it is recommended this data not be published. The manufacturer advised the systems control module be replaced as a potential solution to malfunctions. This was carried out on the 3rd July 2023. The system was observed to similarly malfunction after a short period.

Additional information regarding this dataset is contained in the GSM data acquisition and processing report.
