M.ArMB Arctic mid bathyal
Published date 2015-03Within the UK, Arctic seabed habitats occur at depths greater than 600 m in the Faroe-Shetland Channel. The cooler Arctic waters (typically below 0°C) are subducted below Atlantic waters meaning the u...
M.AtLB Atlantic lower bathyal
Published date 2015-03Atlantic waters are warm (typically >8°C within the UK) and Atlantic seabed habitats occur around most of the UK, excluding depths greater than 300 m in the Faroe-Shetland Channel. The Atlantic lower...
M.AtUA Atlantic upper abyssal
Published date 2015-03Atlantic waters are warm (typically >8°C within the UK) and Atlantic seabed habitats occur around most of the UK, excluding depths greater than 300 m in the Faroe-Shetland Channel. The Atlantic upper...
M.AAUB.Mx.DeeSpo.GeoSpo Geodia and other massive sponges on Atlanto-Arctic upper bathyal mixed sediment
Published date 2015-03This biotope has been found at approximately 500m on the eastern slopes of the Faroe-Shetland Channel, it principally consists of rather small sponge specimens but that practically carpet the seafloor...
M.AAUB.Co.DeeSpo Deep sponge aggregation on Atlanto-Arctic upper bathyal coarse sediment
Published date 2015-03This broad community contains assemblages where sponges dominate sediment habitats. Sponges can be of all morphotypes except encrusting. Aggregations of the Geodia species with other massive forms are...
M.ArLB.Bi Arctic lower bathyal biogenic structure
Published date 2015-03A biogenic structure is formed when reef-forming species, such as cold water corals, attach to any hard substrate present and grow over the surrounding area forming a secondary substrate over the top....
M.AtLB.Sa.UrcCom.GraAcu Gracilechinus acutus norvegicus assemblage on Atlantic lower bathyal sand
Published date 2015-03This biotope consists of aggregations of Gracilechinus acutus norvegicus (previously Echinus acutus norvegicus) on sand substrate. The same epifaunal assemblage is also found on mud and sand in the up...
M.AtUB.Sa.BurOph Burrowing ophiuroid community on Atlantic upper bathyal sand
Published date 2015-03This broad community consisting of assemblages characterised by brittle stars (ophiuroids) that bury in soft sediments with on the tips of the arms visible at the surface. Species may differ with dept...
M.AtLB.Co.SolScl Solitary scleractinian field on Atlantic lower bathyal coarse sediment
Published date 2015-03This broad community is characterised by dense aggregations of solitary cup corals (Caryophylliidae and / or Flabellidae) on sediments including mud and sandy mud and coarse sediments. The species com...
