    This product represents the predicted spatial patterns of species abundance, species richness and species evenness of demersal fish communities in the SEMR. It provides a description of the structure rather than the composition (i.e. specific species) of these assemblages. Structure equates to total species abundance (the total number of individuals), species richness (the total number of species) and species evenness (relative proportions of species). The product can also be used to identify areas in the SEMR that are predicted to have unique combinations of species richness and evenness. This allows managers to identify areas that are predicted to have common or rare types of community structure.

  • This product (i.e. an Access database and csv files) contains data (longitude, latitude and physical data) that explains the predicted spatial patterns of benthic habitats for demersal fish and benthic invertebrates in the SWMR. Predicted patterns for habitats represent point data on a 0.01 decimal degree grid covering most of the SWMR (approximately 400,000 square km).

    This product (i.e. Access data base) contains data (longitudes, latitude and biodiversity attribute variables) that describes the predicted spatial patterns of total species abundance, species richness and species evenness for both benthic invertebrates and demersal fish in the SWMR. The predicted patterns are represent as point data arranged on a 0.1 degree grid (~ 1.2 km2) covering depths 50-1500 metres in the SWMR.

  • This record describes multibeam echosounder data collected on RV Investigator voyage IN2017_C01, 'GAB deep water geological and benthic ecology program' which departed Hobart on the 11 April 2017 and returned to Hobart on the 28 April 2017. The Kongsberg EM122 multibeam echosounder was used to acquire seafloor bathymetry, backscatter information and watercolumn backscatter around the GAB. The EM122 provides a 1 degree by 1 degree angular resolution. The echosounder's nominal frequency is 12 kHz. Data are stored in *.all raw format for bathymetry and backscatter and *.wcd format for watercolumn backscatter at CSIRO. There are 645 files totalling 20.5 GB of raw data in this dataset. Sound velocity profiles were applied to this data during data acquisition. Bathymetry data contained in *.all format are corrected for motion and position. Tide corrections were applied to the processed data. Processed data had outliers removed. Processed line data are available in *.gsf and ascii format, and processed bathymetry and backscatter grids in geotiff format. Additional information regarding this dataset, including information on processing streams, is contained in the GSM data acquisition and processing report. Additional data products may be available on request.

  • This dataset contains the Underway (UWY) data collected on Southern Surveyor voyage SS2013_T02. The voyage took place from Hobart to Freemantle between the 17th June and 29th of June, 2013. This dataset has been processed and 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. The standard Underway (=continuously recorded) dataset from a research voyage includes Navigation (NAV), Sounder, Thermosalinograph (TSG) and Meteorological (MET) data. NAV data includes GPS (Global Positioning System) measurements of latitude, longitude, ship's direction and speed. MET data includes atmospheric temperature, humidity and pressure, wind speed and direction, and incident radiation intensity. Data from "IMOS" (Integrated Marine Observing System) sensors are also included. The sensors are port and starboard radiometers and pyranometers, wind speed; rain and rainrate. Data are recorded at 5 second intervals and stored in NetCDF format. For Public Access data (.csv files, 10 sec and 5 min intervals). See "Download Public Underway data and Processing Reports" link for details.

  • The O&A Trajectory data set includes data collected during the voyages of Australia's Marine National Facility and CSIRO marine research vessels. Trajectory data typically consists of undulating CTD track point data. 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 867,617 position records from 14 voyages and includes water temperature, pressure, water depth, fluorescence 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 3,124,509 position records from 31 voyages collected since 1988. This data includes water temperature, pressure, water depth, fluorescence, salinity (derived), oxygen, eco chloro, eco cdom and eco bp. Individual metadata records have been created for each research voyage.

    Dataset contains monitoring data from field surveys (mainly from crab-traps) on the distribution of European green crab (Carcinus maenas) in mainland Australian coastal waters, from January 1997 onwards. Data are also collected for bycatch of native crab species (including common shore crab Paragrapsus gaimardii, rough rock crab Nectocarcinus integrifrons, and ocean surf crab Ovalipes australiensis). The majority of data comes from one-off trappings in St Vincent Gulf, South Australia, and a suite of sites from SE Victoria (this latter area has been surveyed repeatedly). Some sites were in southern NSW. Data contains details of catch location, date, crab species, crab size, abundance, sex, gonad condition, limb loss, carapace colour. These data were collected as part of CSIRO's studies on the impacts and demographics of introduced marine species in Australian waters and for comparison with green crab distributions in Tasmania.
