M.AtLB.Ro.MixCor Mixed cold water coral community on Atlantic lower bathyal rock and other hard substrata

Published date 2015-03

This broad community contains those biotopes where corals dominate but do not form a living coral reef. A mixture of different coral types can be present. Associated species are similar to 'sparse enc...


M.AtLA.Mu Atlantic lower abyssal mud

Published date 2015-03

Deep-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.Bi Atlantic upper bathyal biogenic structure

Published date 2015-03

A 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.Co Atlantic lower bathyal coarse sediment

Published date 2015-03

Deep-sea coarse sediment has not been sampled widely for infauna so little is currently known about infaunal community structure. Epifauna tend to be sparse mobile species or burrowing fauna such as a...


M.AtMA.Ro Atlantic mid abyssal rock and other hard substrata

Published date 2015-03

Rock and other hard substrate has a more diverse epifaunal community as species attach to the hard surface that in turn attract more fauna. Deep-sea rock is generally encrusted in a range of species i...


M.AtLB.Mu.UrcCom.GraAcu Gracilechinus acutus norvegicus assemblage on Atlantic lower bathyal mud

Published date 2015-03

This biotope consistis of aggregations of Gracilechinus acutus norvegicus (previously Echinus acutus norvegicus) on mud substrate. Gage (1986) reports this assemblage from 700-1400m on pelagic ooze an...
