IR.LIR.K.Sar Sargassum muticum on shallow slightly tide-swept infralittoral mixed substrata
Published date 2015-03Mixed substrata from the sublittoral fringe to 5m below chart datum dominated by the brown seaweed Sargassum muticum. This invasive non-native brown seaweed can form a dense canopy on areas of mixed s...
CR.MCR.SfR Soft rock communities
Published date 2015-03This biotope complex occurs on moderately wave-exposed, circalittoral soft bedrock subject to moderately strong tidal streams. As this complex is found in highly turbid water conditions, the circalitt...
CR.FCR.FouFa.Aasp Ascidiella aspersa on circalittoral artificial substrata
Published date 2015-03Sheltered artificial substrata (such as discarded fishing nets or scrap metal on muddy sediment plains), sometimes subject to variable salinity, with high numbers of the ascidian Ascidiella aspersa wh...
CR.HCR.XFa.ByErSp.Eun Eunicella verrucosa and Pentapora foliacea on wave-exposed circalittoral rock
Published date 2015-03This variant typically occurs on wave-exposed, steep, circalittoral bedrock, boulder slopes and outcrops, subject to varying tidal streams. This silty variant contains a diverse faunal community, domi...
SS.SMx.OMx Offshore circalittoral mixed sediment
Published date 2015-03Offshore (deep) circalittoral habitats with slightly muddy mixed gravelly sand and stones or shell. This habitat may cover large areas of the offshore continental shelf although there is relatively li...
M.ArLB.Sa Arctic lower bathyal 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.HCR.XFa.ByErSp.DysAct Mixed turf of bryozoans and erect sponges with Dysidea fragilis and Actinothoe sphyrodeta on tide-swept wave-exposed circalittoral rock
Published date 2015-03This variant typically occurs on exposed and moderately wave-exposed bedrock and boulders subject to a variety of tidal regimes (from strong through to weak). It is found mainly in the 10-20m depth ra...
M.AtMB.Mu.EreCor.AcaArb Acanella arbuscula assemblage on Atlantic mid bathyal mud
Published date 2015-03This biotope is composed of dense aggregations of the Isidid octocoral Acanella arbuscula on sandy silts and fine grained oozes. It is likely to be functionally similar to a seapen field. Gage (1986)...
CR.MCR.EcCr.CarSwi Caryophyllia smithii and Swiftia pallida on circalittoral rock
Published date 2015-03This biotope is typically found on the upper and vertical faces of very exposed through to wave-sheltered circalittoral bedrock and boulders, which are typically subject to weak tidal streams. It is c...
M.AtMB.Bi Atlantic mid 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....
