This dataset shows the global distribution of seagrasses, and is composed of two subsets of point and polygon occurence data. The data were compiled by UNEP World Conservation Monitoring Centre in collaboration with Dr Frederick T. Short (University of New Hampshire, USA).

This dataset represents Exclusive Economic Zones (EEZ) of the world. Up to now, there was no global public domain cover available. Therefore, the Flanders Marine Institute decided to develop its own database. The database includes two global GIS-layers: one contains polylines that represent the maritime boundaries of the world countries, the other one is a polygon layer representing the Exclusive Economic Zone of countries. The database also contains digital information about treaties. Please note that the EEZ shapefile also includes the internal waters of each country http://www.marineregions.org/eezmethodology.php

Undersea feature names The GEBCO Sub-Committee on Undersea Feature Names (SCUFN) maintains and makes available a digital gazetteer of the names, generic feature type and geographic position of features on the sea floor. The gazetteer is available to view and download via a web map application, hosted by the International Hydrographic Organization Data Centre for Digital Bathymetry (IHO DCDB) co-located with the US National Centers for Environmental Information (NCEI). The data are available in a number of formats including spreadsheet, shapefile, KML, WMS and ArcGIS layer and can be accessed as a REST-style API.

This record describes the datasets collected from the development of a Gene Tagging Tool for the Regional Tuna Tagging Programme (RTTP) which is managed under the auspices of the Indian Ocean Tuna Commission and genetic tagging studies. The aim is to quantify population structures and migratory dynamics which are currently poorly understood. The use of SNP markers lend themselves easily to routine and inexpensive ($10-$20 per fish) screening methodologies. The stock assessment advice is used to assist in the conservation and optimal economic use of this resource. This record describes the datasets collected or resulting from the outcome of the programme.

These data were collected as part of a National Environmental Research Program (NERP) Marine Biodiversity Hub project (Theme 1 National Monitoring Evaluation and Reporting, Project 2 Analysis of approaches for monitoring biodiversity in Commonwealth Waters) undertaken in the Solitary Islands Region in August 2012. The Solitary Islands Key Ecological Feature (KEF) field survey had two broad objectives: 1) deploy and demonstrate various non-destructive field methods and 2) compare sampling patterns. These data comprise those collected using stereo-Baited Remote Underwater Video (stereo-BRUV). Four sixty minute stereo-BRUV drop replicates were deployed at two sites at each of five locations: 40 Acres Reef, Split Bommie, Patch, South and Relic Reef. There were 40 drops in total (4 x 2 x 5). An additional 23 drops were deployed at one of the locations (40 Acres Reef) to examine spatial autocorrelation.

This dataset presents an oceanographic regionalisation for the Australian region using a multivariate pattern classification system, constructed as part of the CSIRO Bioregionalisation Project. The oceanographic regionalisation comprises an analysis of temperature, dissolved oxygen, salinity, nitrate, phosphate and silicate variability with season and depth. Data sources include research vessels, satellites, and surface drifters, and in particular the archive of vertical profiles of temperature, salinity, oxygen and nutrients comprising over 130,000 stations in the seas adjacent to Australia collected as part of the Division of Oceanography's Oceans-EEZ Analysis System.

This study examined the larval biology and ecology of the southern rock lobster (Jasus edwardsii) based on approximately 3000 archived plankton and mid-water trawl samples held, principally, by CSIRO, Tasmanian Aquaculture and Fisheries Institute, and the Marine and Freshwater Research Institute, Victoria. Additional samples were provided by the National Institute of Water and Atmosphere, New Zealand; some samples were opportunistically collected during the project to fill in areas where there was a lack of archived samples. The combined sample set covered the major geographic range of the fishery in Australia (132E/32S - 155E/46S). Details of larval growth, duration and distribution were combined with concurrently collected hydrographic data and satellite based observations to examine possible larval transport mechanisms, connectivity between management zones and physical factors that may influence the supply of larvae on a regional basis. The dataset is primarily in Excel format with a summary of the results presented in a final report to FRDC (project number 96/107).

This record describes AFMA catch and effort data for the Torres Strait Rock Lobster Fishery, held by CSIRO Marine and Atmospheric Research. A number of commercial fisheries operate within the Torres Strait for which logbook data is collected by AFMA. The rock lobster fishery comprises multiple sectors from both Australia and PNG with the two Australian sectors being a Traditional Inhabitant (TIB) sector and a non-Traditional Inhabitant (TVH) commercial sector. Data for the two Australian sectors is collected by AFMA while data for the PNG component of the fishery is collected by PNG Fisheries authorities with an annual summary (total catch) passed to AFMA at the end of each season. Rock lobster catch data also exists for a trawl fishery which operated in the Torres Strait between 1980 and 1986. For the two Australian sectors of the Torres Strait rock lobster fishery, catch reporting is compulsory only in the TVH commercial sector via a logbook program. Reporting of commercial catch from the TIB sector is currently not compulsory and any data that is reported is done on a voluntary basis through processors via a docketbook program. The docketbook system was introduced in 2004 in an attempt to collect commercial catch data from TIB fishers when they sold their catch. The docketbook program has been generally accepted well by TIB fishers since its introduction but has a number of limitations. Although the docketbook program has been successful to some extent, there are significant difficulties with data accuracy and completeness. As the program is also voluntary, not all processors participate in the program or complete records for all sales.
