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.

FAO Major Fishing Areas for Statistical Purposes are arbitrary areas, the boundaries of which were determined in consultation with international fishery agencies on various considerations, including (i) the boundary of natural regions and the natural divisions of oceans and seas; (ii) the boundaries of adjacent statistical fisheries bodies already established in inter-governmental conventions and treaties; (iii) existing national practices; (iv) national boundaries; (v) the longitude and latitude grid system; (vi) the distribution of the aquatic fauna; and (vii) the distribution of the resources and the environmental conditions within an area. For various historical reasons the Areas in the Pacific were not so developed, with the exception of Area 87 corresponding to the CPPS area of competence. Initiatives for closer cooperation between agencies in the interest of better data, not only in the field of tunas, have suggested that some changes are necessary to the present FAO fishing areas/boundaries in the Pacific. The boundaries of fishing areas could be modified and adjusted according to new requirements, but it is inadvisable to introduce too frequent amendments to the already established areas. Revisions to boundaries should only be introduced after consultation with all the national fishery authorities and fishery agencies concerned with the areas under revision. Unless there are other over-riding reasons, boundaries lines should be drawn along 5° lines of longitude and latitude.

The original World Vector Shoreline (WVS) was a digital data file containing the shorelines, international boundaries, and country names of the world. WVS data were processed into NGA’s Vector Product Format in 1995, resulting in the highest resolution demarcation of coastline globally available, the World Vector Shoreline Plus. Six libraries exist, within this single worldwide database, at scales ranging from 1:250,000 to 1:120,000,000. Each library contains a Countries/Coastlines/Oceans (COC) coverage, including both line and area features such as coastlines, political boundary lines, and other lines of separation, administrative areas, and oceans. Each library also contains the following reference coverages: library reference (LIBREF), which gives an overview of the library; tile reference (TILEREF), which defines the tiling scheme for each library; and names placement (GAZETTE), which contains point features that represent the approximate centroid of each locality in the WVS Plus database. The maritime boundaries (MAB) and maritime boundaries supplemental (MBS) coverages contain maritime claims for each country as derived from the Maritime Claims Reference Manual, DOD 2005.1M, 2001. MAB and MBS are found only in the WVS250K library (1:250,000 scale). The bathymetry (BAT) coverage exists only in the WVS003M, WVS012M, and WVS040M libraries and contains depth contours and depth areas derived from the digital bathymetric database product. See the Vector Product Format (VPF) World Vector Shoreline (WVSPLUS) Draft Specification (MIL-PRF-89012A dated August 24, 1999) for a detailed product definition, and the VPF Military Standard (MIL-STD-2407) for more descriptions of VPF.

This data set contains the locations of offshore petroleum titles/leases/tenements, established for exploration and/or production purposes. Data was sourced from the Australia’s National Offshore Petroleum Titles Administrator and Australian States archives. Data for all titles/leases/tenements, generated pre-2011 were sourced from states online archives.

This data contains summaries at 0.1 deg of all suspected and confirmed oil pollution events reported to, or suspected by AMSA. Data on the date, geographic location, source type and ship type was provided by AMSA. This data was summarised over the entire time period (1970-2016) at 0.1 degree resolution and the count of the number of incidents produced. http://www.amsa.gov.au/environment/major-historical-incidents/index.asp

This data set is a summary of seismic survey transects from 1961 to 2015. The data was summarised to 0.1 deg grids and the number of km of the grid surveyed over a 5 year period was calculated. Geoscience Australia is releasing its 2014 version of the Marine Seismic Surveys Shape and Kml files. These files have been updated to include recent openfile surveys. The spatial files have been created from a cleansed, updated collection of p190 navigation files. This navigation collection has grown from the checking of navigation submitted to the GA Repository under the Offshore Petroleum and Greenhouse Gas Storage Regulations http://www.ga.gov.au/metadata-gateway/metadata/record/gcat_f5f24293-c9c1-6ed9-e044-00144fdd4fa6/Marine+Seismic+Survey+Shape+and+Kml+Files+-+2014+Version This data contains geographical information in shapefiles that represent 2D and 3D seismic surveys from 1961 to 2013.They represent most of the seismic surveys shot around Australia. According to Mike Sexton (pers. comm., 2013; GA) 3D surveys are modern surveys that shoot with multiple cables, acquiring many times more data than a 2D survey. The cables have no impact on the environment. Over time, seismic surveys have used a variety of sources commencing with dynamite in the 1960s (usually 50 lbs, but sometimes 200 lbs). The shot spacing was usually of the order of 200 m. Since then, electrical discharges (sparkers), gas-exploders, vibratory sources and air guns have been used. The shot interval has been reduced to about 20 m.

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 shows the global distribution of seagrasses, and is composed of two subsets of point and polygon occurrence data. The data were compiled by UNEP World Conservation Monitoring Centre in collaboration with Dr Frederick T. Short (University of New Hampshire, USA). The boundaries do not represent actual ranges as seagrass are distributed in waters shallow enough for sunlight to penetrate. No surface area calculations should be attempted.
