Description: SeaVoX is a combined SeaDataNet and MarineXML vocabulary content governance group, it is moderated by BODC (https://www.bodc.ac.uk/data/codes_and_formats/seavox/). This polygon data set defines the geographic extent of the terms specified by the SeaVoX vocabulary governance to describe coherent regions of the hydrosphere. It includes land masses enclosing freshwater bodies. The coastline data set used in the shapefile is taken from the World Vector Shoreline data set (scale 1:250,000). Reference for the data set: "polygon data set of the extent of water bodies from the SeaVoX Salt and Fresh Water Body Gazetteer, http://vocab.ndg.nerc.ac.uk/list/C19/current/" The data file follows a hierarchical structure with each region consisting of one or more polygons. This approach was adopted to avoid the need to have overlapping polygons in regions where a sea area included a number of sub-regions, for example the Mediterranean Sea includes the Aegean Sea, Ionian Sea etc. The following gives the level in the structure at which particular regions, which consist of more than one polygon can be found. This level in the structure is given by the polygon's attributes. Attribute: REGION: ARCTIC OCEAN ATLANTIC OCEAN BALTIC SEA INDIAN OCEAN MEDITERRANEAN REGION PACIFIC OCEAN SOUTH CHINA AND EASTERN ARCHIPELAGIC SEAS SOUTHERN OCEAN MAINLAND EUROPE MAINLAND ASIA Attribute: LEVEL_1 ARAFURA SEA DAVIS SEA GULF OF BOTHNIA MEDITERRANEAN SEA NORTH ATLANTIC OCEAN NORTH PACIFIC OCEAN ROSS SEA SOUTH ATLANTIC OCEAN SOUTH PACIFIC OCEAN TIMOR SEA; Attribute: LEVEL_2 MEDITERRANEAN SEA, WESTERN BASIN MEDITERRANEAN SEA, EASTERN BASIN NORTHEAST ATLANTIC OCEAN (40W) NORTHEAST PACIFIC OCEAN (180W) NORTHWEST ATLANTIC OCEAN (40W) NORTHWEST PACIFIC OCEAN (180W) SOUTHEAST ATLANTIC OCEAN (20W) SOUTHEAST PACIFIC OCEAN (140W) SOUTHWEST ATLANTIC OCEAN (20W) SOUTHWEST PACIFIC OCEAN (140W): Attribute: LEVEL_3 BERING SEA CORAL SEA ENGLISH CHANNEL JAPAN SEA NORTH SEA TASMAN SEA YELLOW SEA Attribute: LEVEL_4 CARDIGAN BAY DOVER STRAIT FIRTH OF CLYDE LIVERPOOL BAY NORTH CHANNEL POOLE BAY SOLENT SOLWAY FIRTH Attribute: SUB_REGION This is the lowest level in the structure. This version of the shapefile corresponds to version 9 of the SeaVoX Salt and Fresh Water Body Gazetteer. It includes: 1. Polygons defining the extent of water bodies for the area around the UK from the Marine Environmental Data and Information Network (MEDIN) Marine Gazetteer. 2. Polygons defining the extent of the Caspian Sea and Aral Sea. 3. Definitions of limits of mainland Europe and mainland Asia. Please note that these areas are included purely to help provide context for the extent of the fresh water bodies, there are no political connotations inferred by the use of these names. In this edition of the shapefile version of the SeaVoX Salt and Fresh Water Body Gazetteer, the attribute 'OCEAN' used in previous editions, has been renamed 'REGION'. Likewise the attribute, 'SUB_OCEAN' has been renamed 'SUB_REGION'. Version 9 of C19 - SeaVoX Salt and Fresh Water Body Gazetteer was released to correct a spelling mistake for 'Northern Minch'. However, this spelling mistake was not present in version 8.0 of the shapefile version of the gazetteer. Version 9 of this shapefile has been released to correspond with version 9 of C19.There have been no changes made to the content of the polygons contained within this shapefile as compared with version 8.
