  • This record describes multibeam echosounder data collected from the Marine National Facility (MNF) RV Investigator Voyage IN2020_V01, titled: “Development of William’s Ridge, Kerguelen Plateau: tectonics, hotspot magmatism, microcontinents, and Australia’s Extended Continental Shelf” between January 08 and March 06, 2020 departing from Henderson (WA) and returning back to Fremantle (WA). The Kongsberg EM122 multibeam echosounder was used to acquire seafloor bathymetry, backscatter information and watercolumn backscatter at Rig Seismic Seamount, Williams Ridge, Broken Ridge and on associated transits. 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 2164 files totalling 174 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 not 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 species distribution, abundance and identity data of benthic invertebrates from the Pittwater region, NSW. Epifauna samples were obtained every 3 months from mangroves and saltmarshes between June 1991 and March 1991. Taxa identified consisted of 9 species of molluscs, all of which were gastropods. The data were taken as a control site for similiar sampling in Jervis Bay. The data are part of the Jervis Bay Marine Ecological Study. NB - As the database has been lost, the only data still available are those published in the JERVIS BAY BASELINE STUDIES Final Report.

    This record describes chlorophyll data collected as part of the 1991-1993 Tasmanian Slope Trophodynamics Study undertaken by CSIRO Division of Fisheries. Chlorophyll data were obtained from analyses of filters 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). Analyses were carried out using spectrophotometric methods (cruise SS 01/92) and HPLC (3 remaining cruises), and analysed for chlorophylls a, b and c to give estimates of algal biomass in the water.

    This dataset contains species distribution, abundance and identity data of benthic invertebrates from Batemans Bay, NSW. Epifauna samples from the inter-tidal and subtidal rocky coasts around the bay were sampled twice, in November 1990 and August 1991. The data were taken as a control site for similiar sampling in Jervis Bay. The data are part of the Jervis Bay Marine Ecological Study. NB - As the database has been lost, the only data still available are those published in the JERVIS BAY BASELINE STUDIES Final Report.

    This dataset contains data on fish distributions and occurrences from Jervis Bay, NSW. The data were obtained from sandy beaches around Jervis Bay between October 1988 and July 1991. Beach seine and beam trawl surveys were conducted every 3 months for 3 years. Taxa identified comprised 97 fish species (including 41 species sought by commercial or recreational fishermen and 12 species classified as baitfish) and 14 invertebrate species. Baitfish (predominantly small, schooling species) made up 94% of the total fish catch, and valued fish 6%. Environmental correlations (including water temperature, salinity, waves, clarity, light wind and time of day were examined for various types of fish and invertebrates, and two common fish species Myxus elongatus and Sillago ciliata in particular. The Jervis Bay sandy beach faunas were compared with those over Posidonia beds and in nearby creeks, and with other beaches in Port Hacking and Batemans Bay. NB - As the database has been lost, the only data still available are those published in the JERVIS BAY BASELINE STUDIES Final Report.

    This dataset contains data on species distributions, productivity, reproduction and growth of mangroves and saltmarshes from Jervis Bay, NSW. The data were obtained from a variety of surveys and measurement techniques between October 1988 and July 1991. Taxa identified comprised of about 130 vascular flora species, 15 of which are exotic. Species numbers range from 2 species in the mangroves to more than 80 in the fringe forest. Population structures of the 5 dominant species - Avicennia marina, Aegiceras corniculatum, Casuarina glauca, Sclerostegia arbuscula and Gahnia filum vary spatially. Temporal change in populations of Avicennia has occurred over time intervals of 20 years, the other species appear to have remained stable over the past 50 years. 13 maps on the mangrove and saltmarsh complexes have been prepared at a scale of 1:4000. The Jervis Bay mangroves and saltmarshes were compared with other locations around Batemans Bay and Port Hacking. NB - As the database has been lost, the only data still available are those published in the JERVIS BAY BASELINE STUDIES Final Report.

    The Interim Register of Marine and Nonmarine Genera (IRMNG) is a provisional (or ‘interim’) compilation of genus names – including species names in many cases – and covers both living and extinct biota into a single system to support taxonomic and other queries dealing with e.g. homonyms, authorities, parent-child relationships, spelling variations and distinctions between marine and non-marine or fossil and recent taxa. Taxonomic names in IRMNG are assigned flags to distinguish between marine vs. non-marine, and extant vs. fossil status; they are also arranged into a simple management hierarchy for navigation purposes, compilation of statistics per taxonomic group and more. Fuzzy matching is also supported (using "Taxamatch") so that a misspelled name can in most instances be reconciled to a correctly spelled name at genus or species rank, where this is held. IRMNG was a project of OBIS Australia designed to assist in the provision of marine species data to OBIS, by permitting the discrimination of marine from nonmarine (and extant from fossil) species records on the basis of the genus name portion of their scientific name (normally, genus + species, or genus + species + infraspecies if applicable). The aim of the project is to (a) assemble as complete a list as possible of the estimated 150,000 extant and 50,000 fossil generic names in current use, plus their possible further 250,000-300,000 synonyms, and (b) flag as many of these as is possible with their marine/nonmarine, and extant/fossil, status. Relevant species lists are also being attached to the "correct" instances of genus names as available. IRMNG was developed and based at CSIRO, Australia from 2006-2014, and from 2016 onwards it is now hosted at VLIZ, Belgium: http://www.irmng.org/

The data are part of the Jervis Bay Marine Ecological Study. NB - As the database has been lost, the only data still available are those published in the JERVIS BAY BASELINE STUDIES Final Report.

  • The CSIRO Oceans and Atmosphere (O&A) previously CSIRO Marine and Atmospheric Research (CMAR) CTD (Conductivity Temperature Depth) dataset includes data collected since 1982 during the voyages of Australia's Marine National Facility, and of various CSIRO marine research vessels. CTD data typically consists of vertical profiles binned at 2-metre intervals. Data usually includes conductivity, temperature, depth and salinity (derived), and may also include any or all of oxygen, fluorescence, optical back scatter (OBS), pH and transmittance. Individual metadata records have been created for each research voyage. The data is held in the O&A Information & Data Centre Data Warehouse, which currently holds over 14,321 CTD station records from more than 285 voyages.
