M.ArLB.Mu Arctic lower bathyal mud
Published date 2015-03Deep-sea mud sediments have a diverse infaunal community dominated by polychaetes. Epifauna tend to be sparse, mobile species, but aggregations of erect fauna such as glass sponges, seapens and soft c...
M.AtMB.Mu.UrcCom.GraAcu Gracilechinus acutus norvegicus assemblage on Atlantic mid bathyal mud
Published date 2015-03This biotope consists of aggregations of Gracilechinus acutus norvegicus (previously Echinus acutus norvegicus) on mud substrate. Gage (1986) reports this assemblage from 700-1400m on pelagic ooze and...
CR.LCR.BrAs.AmenCio Solitary ascidians, including Ascidia mentula and Ciona intestinalis, on wave-sheltered circalittoral rock
Published date 2015-03This biotope predominantly occurs on the upper faces of wave-sheltered (often sealochs) circalittoral bedrock, boulder and cobble slopes with little tidal flow. Apart from the solitary ascidians Ciona...
M.AtMA.Sa Atlantic mid abyssal sand
Published date 2015-03Deep-sea sand sediments have a diverse infaunal community dominated by polychaetes. Epifauna tend to be sparse, mobile species, or burrowing fauna such as anemones and brittlestars visible at the surf...
CR.LCR.BrAs.LgAsSp Large solitary ascidians and erect sponges on wave-sheltered circalittoral rock
Published date 2015-03This biotope is typically found on silty circalittoral bedrock and boulders in wave-sheltered channels subject to varying amounts of tidal flow. These fully marine inlets and channels have steep, ofte...
M.AtLA.Bi Atlantic lower abyssal 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.AAUB.Mu Atlanto-Arctic upper bathyal mud
Published date 2015-03Deep-sea mud sediments have a diverse infaunal community dominated by polychaetes. Epifauna tend to be sparse, mobile species, but aggregations of erect fauna such as glass sponges, seapens and soft c...
M.AtUB Atlantic upper 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 upper bathyal i...
M.ArMB.Mx Arctic mid bathyal mixed sediment
Published date 2015-03Deep-sea mixed sediment has not been sampled widely for infauna so little is currently known about infaunal community structure. Epifauna tend to be sparse mobile species. In the absence of ecological...
M.AtLB.Mu.DeeSpo Deep sponge aggregation on Atlantic lower bathyal mud
Published date 2015-03This broad community contains assemblages where sponges dominate sediment habitats. Sponges can be of all morphotypes except encrusting. Aggregations of the glass sponge Pheronema carpenteri have been...
