    Set of maps showing dissolved oxygen by depth linearly interpolated from CARS2000 mean and seasonal fields to 0.1 degree spaced grid. These maps form part of a series of maps showing the variation of temperature, salinity, oxygen, silicate, phosphate, and nitrate in Australia's Oceans. Each feature in the series has been separately mapped at depths of 0, 150, 500, 1000 and 2000 metres. These maps have been produced by CSIRO for the National Oceans Office, as part of an ongoing commitment to natural resource planning and management through the 'National Marine Bioregionalisation' project.

    Map showing the annual mean at surface of dissolved oxygen in Northern Marine Region produced from CARS2000 mean and seasonal fields 0.1 degree spaced grid. This map has been produced by CSIRO for the National Oceans Office, as part of an ongoing commitment to natural resource planning and management through the 'National Marine Bioregionalisation' project.

    ESRI grids showing dissolved oxygen, linearly interpolated from CARS2000 mean and seasonal fields to 0.1 degree spaced grid, at depths of 0, 150, 500, 1000 and 2000 metres. The loess filter used to create CARS2000 resolves at each point a mean value and a sinusoid with 1 year period (and in some cases a 6 month period sinusoid - the "semi-annual cycle".) The provided "annual amplitude" is simply the magnitude of that annual sinusoid. CARS is a set of seasonal maps of temperature, salinity, dissolved oxygen, nitrate, phosphate and silicate, generated using Loess mapping from all available oceanographic data in the region. It covers the region 100-200E, 50-0S, on a 0.5 degree grid, and on 56 standard depth levels. Higher resolution versions are also available for the Australian continental shelf. The data was obtained from the World Ocean Atlas 98 and CSIRO Marine and NIWA archives. It was designed to improve on the Levitus WOA98 Atlas, in the Australian region. CARS2000 is derived from ocean cast data, which is always measured above the sea floor. However, for properties which do not change rapidly near the sea floor, this would not lead to a significant error. All the limitations of CARS2000 also apply here.

    This dataset contains the processed Dissolved Oxygen Sensor data collected on Franklin voyage FR 02/97. The voyage took place in the Victorian and eastern South Australian coastal waters during 24 January - 4 February 1997. This dataset has been processed and is archived within the CSIRO Marine and Atmospheric Research Data Centre in Hobart. Additional information regarding this dataset is contained in the cruise report for this voyage and/or the data processing report (as available). The Dissolved Oxygen measurements from this sensor (mounted on the CTD apparatus) are calibrated against dissolved oxygen measurements from Niskin Bottle samples taken on the same CTD cast. Where present, the Dissolved Oxygen Data are included within the relevant CTD dataset for archiving and/or download.

    This record describes the dissolved oxygen data collected as part of the 1991-1993 Tasmanian Slope Trophodynamics Study undertaken by CSIRO Division of Fisheries. Samples for Dissolved Oxygen were taken from Niskin bottle samples at a range of depths (surface to 1500 meters) on 4 cruises of FRV "Southern Surveyor" on three 60 km transects across the continental shelf to the south and south-east of Tasmania in July 1991 (cruise SS 02/91), February 1992 (cruise SS 01/92), November 1992 (cruise SS 04/92) and April 1993 (cruise SS 03/93).

    NetCDF version of the NODC World Ocean Atlas 2005 (Climate and Forecasting Metadata conventions conforming) to supply the CSIRO and broader scientific community with a machine transparent, portable and self-describing version of the World Ocean Atlas 2005 (National Oceanographic Data Centre, 2006; Locarnini et al., 2006; Antonov et al., 2006; Garcia et al.,2006a,b) dataset. This Atlas is referred to by the National Oceanographic Data Center (NODC - http://www.nodc.noaa.gov) with the identifier WOA05. NODC offers the WOA05 in ASCII text format that is highly portable but not generally compact, self-describing or very efficient for processing and visualising. The ASCII or netCDF version of the WOA05 can be used to initialise numerical models, verify numerical model solutions, or for general oceanographic and meteorological analysis and can be imported into most plotting and analysis tools, or numerical models, that can read netCDF files. Contains temporal and spatial representation of in-situ temperature, salinity, oxygen and dissolved inorganic nutrients at 1 X 1 deg resolution with standard levels for the analysed fields of 0, 10, 20, 30, 50, 75, 100, 125, 150, 200, 250, 300, 400, 500, 600, 700, 800, 900, 1000, 1100, 1200, 1300, 1400, 1500, 1750, 2000, 2500, 3000, 3500, 4000, 4500, 5000 and 5500 metres.

    Temperature, salinity, oxygen, silicate, phosphate, and nitrate, linearly interpolated from 1/8 degree spaced "high resolution" CARS2000 mean and seasonal fields to a 0.1 degree spaced grid. Values obtained for seafloor by vertical linear interpolation, which is possible because CARS2000 is mapped to one depth level below seafloor by least squares quadratic filter projection of horizontally and vertically adjacent data points. The loess filter used to create CARS2000 resolves at each point a mean value and a sinusoid with 1 year period (and in some cases a 6 month period sinusoid - the "semi-annual cycle".) seafloor_10thdeg.nc.gz contains only mean values and not seasonal values as CARS do not resolve seasonal cycles below 1000m depth, and most of this region is deeper than 1000m. CARS is a set of seasonal maps of temperature, salinity, dissolved oxygen, nitrate, phosphate and silicate, generated using Loess mapping from all available oceanogrpahic data in the region. It covers the region 100-200E, 50-0S, on a 0.5 degree grid, and on 56 standard depth levels. Higher resolution versions are also available for the Australian continental shelf.
