This record describes magnetometer data collected on RV Investigator voyage IN2023_V01, titled "Antarctic Bottom Water Production in the past: Records from marine sediments, Cape Darnley, East Antarctica". The voyage took place between 25th January, 2023 and 2nd March, 2023 departing from Henderson's (WA) and arriving in Hobart (TAS).

The SeaSPY2 magnetometer uses an omnidirectional Overhauser sensor that requires no realignment or recalibration and has no heading error. The instrument has an absolute accuracy of 0.1 nT, sensor sensitivity of 0.01 nT and resolution of 0.001 nT.

Data are stored in .CSV and .MMS data files at CSIRO. 15 final files for 150 MB were exported as .csv files in this dataset.

No processing has been conducted on this data. A total of 3,909 track kilometre's of magnetometer data was collected.

The magnetometer was towed ~300 m astern of the ship and a layback value of 361 was applied to the magnetometer data. This was the total distance behind the ship's positioning reference point.

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