This record describes magnetometer data collected on RV Investigator voyage IN2019_V04, 'Hotspot dynamics in the Coral Sea: connections between the Australian plate and deep Earth' which departed Cairns on the 7th August 2019 and returned to Brisbane on the 3rd September 2019.

The instrument is a Marine Magnetics SeaSPY2 magnetometer and was deployed while transiting during the voyage in the Coral Sea, within the EEZ of Australia, Papua New Guinea, Solomon Islands and New Caledonia. Data are stored in .CSV and .MMS data files at CSIRO. 872 MB of raw data was acquired in this dataset.

No processing has been conducted on this data.

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.”

The magnetometer was towed 300m astern of the ship and a layback value of 361m 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.
