The O&A Trajectory data set includes data collected during the voyages of Australia's Marine National Facility and CSIRO marine research vessels. Trajectory data typically consists of undulating CTD track point data. The subset extracted for MARVL contains data on the continental shelf as defined by the 200 metre depth contour from the 2012 Bathymetric dataset merged (spatial union) with the Exclusive Economic Zone (EEZ) in the Australian Maritime Boundary dataset (http://www.ga.gov.au/metadata-gateway/metadata/record/gcat_63565) available from Geosciences Australia (GA). This subset of the data contains 867,617 position records from 14 voyages and includes water temperature, pressure, water depth, fluorescence and salinity (derived) and spans from 1995 to the present. The full data set is held in the O&A Information & Datacentre Data Warehouse, which currently holds over 3,124,509 position records from 31 voyages collected since 1988. This data includes water temperature, pressure, water depth, fluorescence, salinity (derived), oxygen, eco chloro, eco cdom and eco bp. Individual metadata records have been created for each research voyage.
