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. 34.0MB 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. Additional information regarding this dataset is contained in the GSM data acquisition and processing report. {"type": "Polygon", "coordinates": [[[139.7613, -47.4786], [147.6448, -47.4786], [147.6448, -42.8435], [139.7613, -42.8435], [139.7613, -47.4786]]]} 139.7613 147.6448 -47.4786 -42.8435 RV Investigator survey information documentDigital RV Investigator survey information HTML MNF home page documentDigital Marine National Facility home page HTML Data Access Portal documentDigital Link to the CSIRO Data Access Portal HTML Underway Visualisation Tool documentDigital Link to visualisation tool for Near Real-Time Underway Data (NRUD) HTML Unnamed resource documentDigital License Graphic PNG
