This record describes gravity data collected on RV Investigator voyage IN2023_V02, titled "Gigantic submarine landslide offshore western Tasmania: risk mitigation for shelf derived tsunami in Australia", which departed Hobart on March 24 and returned to Hobart on April 30, 2023.
The gravity meter instrument is a MicroG Lacoste Air-Sea II. Data are stored in .ENV and .DAT data files at CSIRO. There are 24 files totalling 348 MB of raw data in this dataset.
Note: The gravity meter (ASII) was operated until the 13/04/2023 (UTC) when it started to develop periods of erratic movement and displaying large differences between the Spring Tension (ST) and Gravity (Grav) values. A suspected gyro fault rendered the system offline for the remainder of the voyage.
A start of voyage wharf tie was undertaken in Hobart on 23-03-2023 (UTC) using a Scintrex Autograv CG-5. Wharf tie data can be found in "Hobart_wharf_tie_2022_03_23.TXT", which is stored with the raw data. Due to the aforementioned issue with the gravity meter, no end of voyage gravity wharf tie was undertaken.
No processing has been conducted on this data.
Additional information regarding this dataset is contained in the GSM data acquisition and processing report.
