O
Region I is the most northerly OSPAR region, characterised by its harsh climate and ice coverage although the ecosystems of this region are still rich. In spite of its low population density, human activities such as fishing and offshore petroleum production remain significant. +
The Greater North Sea is one of the busiest maritime areas. Offshore activities related to the exploitation of oil and gas reserves, and maritime traffic are very important. Two of the world's largest ports are situated on the North Sea coast, and the coastal zone is used intensively for recreation. +
The Celtic Seas region contains wide variations in coastal topography, from fjordic sea lochs, to sand dunes, bays, estuaries and numerous sandy beaches. The large range of habitats in the region supports a diverse fish fauna. Although traditional maritime activities, such as fishing, take place in the Celtic Seas, there is ongoing development of tourism. +
The bottom topography of Region IV and coastlines are highly diversified, including the continental shelf and slope and parts of the abyssal plain. Ecosystems in Region IV are very rich, support a rich fish fauna and have a particular importance for migratory birds. Main human activities in Region IV are fishing, maritime transport and tourism. +
Region V represents the deep waters of the North-East Atlantic extending across the abyssal plain and the Mid-Atlantic Ridge, and including many seamounts. There have been recent discoveries of a number of different fragile deep-sea habitats (such as hydrothermal vents, carbonate mounds, coral gardens and sponge communities). Human population in the region is restricted to the Azores Archipelago. The main human activities are fishing and maritime transport. +
Terms used to describe 'Occurrence' of species. +
Species which may be listed as alien or introduced but whose occurrence has not been specified. +
Species that are demonstrating aggressive spread and there is concern about its spread OR species where some concern has been recorded- this may be due to known records of its invasiveness and impacts in other areas of their known introduced range. +
Seabed beyond three miles (5 km) from the shore. +
0.5-<5 psu (included under MNCR Low, <18 psu) +
An organism which feeds on a mixed diet including plant and animal material (from Lincoln ''et al.'', 1998). +
Different life stages migrate into different habitats, or part of habitat (e.g. copepods) (Lincoln ''et al.'', 1998). +
Any part of the coast not within a marine inlet, strait or lagoon, including offshore rocks and small islands. This includes MNCR types; linear coast, islands / rocks and semi-enclosed coast. +
Organisms that live in a 'U' or 'Y' shaped burrow where water is drawn through the burrow (adapted from Kristensen ''et al.'', 2012). +
Free-swimming larvae of Ophiuroidea, distinguished by four pairs of arms supported by skeletal rods (Stachowitsch, 1992). +
(1) derived from, or showing the properties of a living organism; (2) containing carbon, applied to molecules. +
