This dataset contains the processed Expendable Bathythermograph (XBT) data collected on Australia's Marine National Facility (MNF) RV Franklin and RV Southern Surveyor. XBT data typically comprises temperature and depth readings relayed to the surface at intervals of 0.1 seconds as the probe passes through the top few hundred metres of the ocean. This dataset has been QCed by the CSIRO Oceans & Atmosphere's (Formerly CSIRO Marine and Atmospheric Research) Ocean Observing Networks (OON) group. The data can be retrieved via CMAR Data Trawler, please see link below. The data is also available via the international National Oceanographic Data Center (NODC) Global Temperature-Salinity Profile Program (GTSPP) (Franklin platform code: 09FA and call sign: VJJF, Southern Surveyor platform code: 09SS and call sign: VLHJ) and Australian Ocean Data Network (AODN). 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 47 XBT station records from 15 voyages and includes temperature, pressure 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 724 XBT station records from more than 72 surveys collected since 1985.
