RV Investigator Voyage IN2020_E01 Magnetometer Data
This record describes magnetometer data collected on RV Investigator voyage voyage IN2020_E01 (Trials and Calibration) which departed Hobart on the 29th July 2020 and returned to Hobart on the 6th August 2020. The purpose of this voyage was to undertake post port-period equipment calibrations and commissioning, sea trials and personnel training.
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. 0.68 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 361 m was applied to the magnetometer data. This was the total distance behind the ship's positioning reference point.
Note: The magnetometer was only deployed for a short period (between 23:04 & 23:51 on the 03/08/2020 - UTC) for training purposes only.
Additional information regarding this dataset is contained in the GSM data acquisition and processing report.
