Full description

This record describes gravity data collected on RV Investigator voyage IN2025_E01, Trials and calibrations, which departed Hobart on the 19th February 2025 and returned to Hobart on the 1st March, 2025.

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 154 MB of raw data in this dataset. A wharf tie was undertaken at Hobart location on 2025/3/7 (prior to IN2025_V01) using a Scintrex Autograv CG-5. Wharf tie data can be found in GravityTie_in2025v01_Hobart_250307.TXT, which is stored with the IN2025_V01 raw data.

During this voyage, calibration lines were run for the Air-Sea II to re-establish calibration values after the system was repaired and reinstalled on the vessel (re-installed 30 Sep 2024). Data from the calibration lines were sent to Micro-G Lacoste for processing. New calibration values were applied within the ASII_HW.ini at the end of the voyage on 1st March 2025.

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