Underway - [view map]

The CMAR Optimized Voyage Tracks displayed in the WMS associated with this record are derived from underway GPS data collected since 1986 by Australia's Marine National Facility during research voyages. For most of these voyages, five minute underway digital data is available. The underway data set typically includes GPS location, Sea Surface Salinity and temperature, and Meteorology Station data. Later voyages also recorded digital echo sounder data. Individual metadata records have been created for each research voyage. The data is held in the CMAR Data Warehouse, which currently holds underway GPS data for more than 200 voyages.
