The instrument is a Marine Magnetics SeaSPY2 magnetometer and was deployed continuosly for the voyage except during 2D Multi-channel Seismic acquisition and Rock Dredging operations. Data are stored in .CSV and .MMS data files at CSIRO. 40.7 GB of raw data was acquired in this dataset. No processing has been conducted on this data. 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. {"type": "Polygon", "coordinates": [[[70.0, -57.0], [116.0, -57.0], [116.0, -30.0], [70.0, -30.0], [70.0, -57.0]]]} 70.0 116.0 -57.0 -30.0 Geophysical Survey and Mapping website information for this data set documentDigital Geophysical Survey and Mapping website information for this data set and link to downloading data.
