ESRI grids showing half lunar mean and maxium tidal currents for the Australian Shelf. The tide data was generated from a tide model for the Australian Shelf which was set up for the region limited by 0 degrees S to 45 degrees S and 109 degrees E to 160 degrees E. The spatial and temporal resolution of the model output is 0.067 degrees in both latitude and longitude and half a lunar cycle respectively. The arc info grided data was generated by Rick Smith and mapped by Donna Hayes.

ESRI grid of mean sea surface currents derived from annual and semi-annual temperature and salinity cycles stored in CARS2000. 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. These grids 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. Variations in onscreen colour representation or printed reproduction may affect perception of the contained data.

ESRI grid showing ocean primary production extracted from global observations of ocean colour data from the moderate resolution imaging spectroradiometer (MODIS). This grid 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. Chlorophyll accuracy is about ± 20%.

The Northern Region Circulation (MECO) Model was developed as part of the FRDC Surrogates 1 project. It covers the region from Joseph Bonaparte Gulf to Torres Strait with a fixed horizontal resolution of 0.05 degrees. Outputs included sea level, currents, bottom stress, and other physical parameters. For this dataset the monthly mean non tidal currents for the Northern Marine Region were used to create GIS map layers. Currents are modeled and are not validated.

ESRI grid showing the mean incident light for each quarter. This data is the surface solar irradiance data obtained for NASA/GISS to allow the prodction of photosynthetically active solar irradiance fields to allow the calculation of primary productio using satellite ocean colour products. The information comes from the Internation Satellite Cloud Climatology Project (ISCCP) using C1 data from multiple geostationary and polar orbiting meterological satellites to provide a global view of the occurrence and properties of clouds. Atmospheric, cloud and surface data from ICSSP are used as input along with a scheme for computing clear-sky irradiance from the solar zenith angle, air properties, and surface reflectance. The scheme then uses simple cloud properties (cloud fraction, cloud optical thickness, and diffuse albedo) to produce total and photosynthetically active solar irradiance fields (Bishop and Rossow 1991; ISCCP Documentation of Cloud Data; Frouin et al. 1989). Input and output data fields are given in a 2.5° latitude and longitude grid. These grids 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.

The Northern Region Circulation Model was developed as part of the FRDC Surrogates 1 project. It covers the region from Joseph Bonaparte Gulf to Torres Strait with a fixed horizontal resolution of 0.05 degrees. Outputs included sea level, currents, bottom stress, and other physical parameters. For this dataset the maximum current velocity (max u & V) were used to create GIS map layers

Prawn larval density recorded from stepped oblique bottom to surface plankton tows in Albatross Bay. Monthly cruises were carried out between March 1986 and April 1992, at twenty-one stations in Albatross Bay, Gulf of Carpentaria. Prawn larval densities were measured and salinity-temperature profiles taken. This data 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 the ocean Mixed Layer Depth annual amplitude and annual mean, calculated from the oceanographic temperature and salinity cast data used to generate CARS2000. These grids 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. CARS2000 is derived from ocean cast data, which is always measured above the seafloor. However, for properties which do not change rapidly near the seafloor, this would not lead to a significant error.

ESRI shape files showing prawn larval density form stepped oblique bottom to surface plankton tows in Albatross Bay. Monthly cruises were carried out between March 1986 and April 1992, at twenty-one stations in Albatross Bay, Gulf of Carpentaria. Prawn larval densities were measured and salinity-temperature profiles taken. These shape files 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.

Between March 1986 and April 1992, monthly cruises were carried out at 21 stations in Albatross Bay, Gulf of Carpentaria. Prawn larval densities were measured and salinity-temperature profiles taken. Prawn larval density from stepped oblique bottom to surface plankton tows. Net sizes were 142 or 140 m mesh, 250 micron mesh with a 0.5 x 0.5 metre square frame, stepped-oblique tow. In this dataset Penaid prawn counts were recorded to genus level for all larval stages.
