    This dataset contains a time-series of oceanographic data collected at the 50m coastal station off Rottnest Island, Western Australia (lat. 32 deg. 00 min. S, long. 115 deg. 25 min. E). The station was set up under the CSIRO coastal monitoring programme in the 1950s and is sampled for temperature, salinity, dissolved oxygen, nitrate and silicate at depths of 0, 10, 20, 30, 40 and 50m below the surface. Sampling is undertaken at monthly intervals from April 1951 and continued until July 2002, after which the sampling regime was irregular. The data are stored on-line as part of the CMR hydrology archive in Hobart and are available via the CMAR Data Trawler see link below. Since April 2009 the sampling became part of the IMOS program. The current sampling regime is approximately monthly for 11 or 12 months per year. The IMOS sampling includes additional Biological data. The ongoing data is currently available via the IMOS portal. Please see Data Links below. Additional copies of the data up to 1989 are deposited with the NODC data archive (World Data Centre-A) in the U.S.A., and details of relevant data files can be viewed via their website by requesting the file inventory for this coastal station which is NODC platform code "09K2". Station details, plus printed versions of the data up to the end of 1960, have been published in CSIRO's "Oceanographical Station List" series.

  • The O&A Hydrology data set includes data collected during the voyages of Australia's Marine National Facility, and of various CSIRO marine research vessels and coastal stations. Hydrology usually consists of salinity and nutrient values obtained by analysing water samples taken at several depths at each station. 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 2,555 Hydrology station records from 78 surveys and includes temperature, pressure and salinity 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 31,796 Hydrology station records from more than 601 surveys collected since 42. This data includes temperature, pressure and salinity, and may also include any or all of nitrate, nitrite, oxygen, phosphate, silicate and ammonia. Individual metadata records have been created for each research voyage.

  • The CMAR Hydrology data set includes data collected since 1942 during the voyages of Australia's Marine National Facility, and of various CSIRO marine research vessels and coastal stations. Hydrology data usually consists of salinity and nutrient values obtained by analysing water samples taken at several depths at each station. The data may include temperature for some depths, nutrients may include any or all of ammonia, nitrite, phosphate, nitrate, silicate, oxygen. Individual metadata records have been created for each research voyage. The data is held in the CMAR Data Warehouse, which currently holds over 45,000 Hydrology station records from more than 500 voyages.
