This dataset contains the Conductivity-Temperature-Depth (CTD) data collected on Southern Surveyor voyage SS2011_v03. The voyage took place south-west of Tasmania 47 S and 140 E from 1st to the 7th August 2011. This dataset has been processed and archived within the CSIRO Marine and Atmospheric Research Data Centre in Hobart. Additional information regarding this dataset may be contained in the Voyage Summary and the Data Processing Report.

This map shows chlorophyll a concentrations in Albatross Bay, Gulf of Carpentaria. Phytoplankton pigment composition (chlorophyll a concentration) was measured in Albatross Bay, Gulf of Carpentaria, northern Australia. Four sites were sampled over six years between August 1986 and April 1992. In the last two years samples were taken at the bottom of the water column in addition to mid-depth. 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.

Map showing prawn larval distribution of commercial and non-commercial species. The data was recorded from stepped oblique bottom to surface plankton tows, 140-142um nets. 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.

Map showing sea surface temperature quarterly and overall means in the Northern Marine region. The CSIRO Marine Research Remote Sensing facility automatically receives and archives data from the USA's National Oceanographic and Atmospheric Administration (NOAA) satellites. Up to 18 passes per day are tracked to receive data. The Advanced Very High Resolution Radiometer (AVHRR) data is received on the High Resolution Picture Transmission (HRPT) signal. Within an hour of reception, these data are automatically processed into full resolution sea surface temperature (SST) images. Raw data originate from the AVHRR sensor on various NOAA polar orbiting satellites, received at various stations around Australia and consolidated ("stitched") by the CSIRO Earth Observation Centre. The stitching removes redundancy and minimises data corruption. Processing from the stitched archive to produce SST is carried out in the CMR Remote Sensing Facility in Hobart using the split window algorithm of McMillin for NOAA9 and NOAA12 satellites and the NLSST (NOAA non-linear SST) algorithm for the other satellites. Cloud-clearing is performed based on the algorithm of Saunders and Kriebel. Each map is made by combining the estimates over the composite period using a time and spatial neighbourhood median filtering method. Each pixel of the images is the 65 percentile of all cloud-cleared SST estimates during the composite period and within a 4x4 km region. The compositing process also removes most residual cloud contamination. 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.

Buoys were released in the Southern Ocean (in Antarctic waters), in the Indian and Pacific Oceans, in the Tasman Sea and in The Great Australian Bight. 143 deployments were made between 1975 and 1995. The buoys were tracked by the NASA weather satellite NIMBUS-6, and later by the French System ARGOS aboard the satellite TRIOS-N. Buoy types include 4.5 m PVC/fiberglass spars (Cresswell et. al. CSIRO), 5m spars (Australian Bureau of Meteorology), and two variations of 2 m "torpedo" buoys (Cresswell, Richardson and Wood). Most of the buoys were drouged with 7.2m parachute at 20m depth. Sea surface temperature data was recorded and transmitted to satellite. Buoy drift speed and direction were calculated from successive satellite fixes.
