RV Investigator Voyage IN2024_T01 Magnetometer Data

This record describes magnetometer data collected on RV Investigator voyage IN2024_T01, 'Transit Voyage: Fremantle to Hobart.' The primary objective of the voyage was the safe and timely transit of RV Investigator from Fremantle to Hobart in preparation for the following research voyage. During the transit various research projects were conducted, along with outreach, familiarisation and training activities. The voyage departed Fremantle on the 09 March and returned to Hobart on the 20 March.

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. 132 MB of raw data was acquired in this dataset.

No processing has been conducted on this data.

The magnetometer was towed 300 m astern of the ship and a layback value of 376 m was applied to the magnetometer data. This was the total distance behind the ship's positioning reference point.
