M.AtLA.Mx Atlantic lower abyssal 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.AtUB.Ro Atlantic upper bathyal rock and other hard substrata
Published date 2015-03Rock 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.AtUB.Ro.BarCom.BatHir Bathylasma hirsutum assemblage on Atlantic upper bathyal rock and other hard substrata
Published date 2015-03Biotope dominated by the barnacle Bathylasma hirsutum. Observed on bedrock in high current areas. Barnacle coverage may not be dense. This assemblage was also identified in the mid bathyal, but the as...
M.AtMB.Sa.BurAne Burrowing anemone field in Atlantic mid bathyal sand
Published date 2015-03This broad community includes sediment biotopes where burrowing anemones are the dominant fauna. On Atlantic mid bathyal sand, the community comprises Cerianthid anemones which are likely to be a diff...
M.AtUB.Bi.CorRee.LopPer Atlantic upper bathyal live Lophelia pertusa reef (biogenic structure)
Published date 2015-03Scleractinian coral reefs formed predominantly by Lophelia pertusa in the upper bathyal zone. Lophelia attaches to any hard substrate present and then grows outwards forming a hard reef structure. Lop...
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...
LS.LSa.FiSa.Po Polychaetes in littoral fine sand
Published date 2015-03Moderately exposed or sheltered beaches of medium and fine, usually clean, sand, though the sediment may on rare occasions contain a small silt and clay fraction. The sediment is relatively stable, re...
M.AtMB.Sa.UrcCom.CidUrc Cidarid urchin assemblage on Atlantic mid bathyal sand
Published date 2015-03This biotope is characterised by sparse and occasionally agreggated Cidarid urchins on sand substrates. The same epifaunal assemblage is also found on coarse sediment and in the upper bathyal but asso...
M.AtMB.Mx.XenCom.SyrFra Syringammina fragilissima field on Atlantic mid bathyal mixed sediment
Published date 2015-03Assemblage characterised by dense aggregations of the xenophyophore Syringammina fragilissima on mixed sediment. Associated species will vary with depth but may include squat lobsters (Munida), Ophiur...
M.AtUB.Co.SpaEnc Sparse encrusting community on Atlantic upper bathyal coarse sediment
Published date 2015-03This broad community includes all biotopes that are characterised by encrusting species including deep-sea sponges, serpulid worms, cup corals and Anoniimid bivalves. Associated species can include sq...
