Bare muddy sand with deep black layer at 2.7 to 3.7m BCD. Very worked with large Arenicola marina mounds. Algae attached to pebbles are mainly Cystoclonium purpureum, Laminaria saccharina and Chorda filum. Pomatoschistus minutus and juvenile flatfish frequent. Suction sample 2 - included 36 species of which the annelid worms Mediomastus fragilis and Polydora ?caeca and the bivalve mollusc Fabulina fabula (juveniles) were dominant. The community is present mainly as a narrow transition between the community on coarse substrata extending to about 2.5m BCD and the deeper soft mud community present below about 3m BCD. The most conspicuous feature on the seabed are the mounds of Arenicola marina. Remnants of the shallower community occur where there are pieces of hard substrata present. Individuals of the horse mussel Modiolus modiolus are present. Mobile species include juvenile flatfish, sand gobies Pomatoschistus minutus, and mysid shrimps. The shallow muddy sand community is distinguishable from the other communities described particularly because of the abundance of algae and the absence of Chone sp. |

Plain of soft mud with burrows and mounds of Arenicola marina. Occasional arms of brittlestars Amphiura brachiata. Suction sample 3 - soft sublittoral mud from about 2.7m BCD. `5 species were found including the bivalve mollusc Mysella bidentata, Nematoda indet and the worm Mediomastus fragilis, which comprised 96% of the individuals present. The community was present between depths of about 3 and 7m BCD. The mud has mounds of Arenicola marina, and also mounds and burrows of unidentified origin. The mud has patchy coating of diatoms. There are common sand gobies, Pomatoschistus minutus and frequent hermit crabs and the common starfish Asterais rubens. The burrowing anemone Cerianthus lloydii, sea cucumber Leptosynapta inhaerens, the brittlestar Amphiura brachiata, the snake blenny Lumpenus lampretiformis also occur in this community. There are also large numbers of juvenile flatfish. |

Sublittoral fine sand with common Arenicola mounds and burrows at 2m BSL. Other species included frequent Chorda filum, occasional Laminaria saccharina, occasional filamentous red algae, occasional cover of diatoms on the sand, rare patches of Beggiatoa, common Pagurus (occuring with Hydractinia), frequent juvenile flatfish, frequent sand? gobies, occasional Carcinus maenas, rare Chone sp., rare Buccinum, rare Inachus sp., rare Gasterosteus aculeatus, occasional Asterais rubens and occasional Asteropecten. Numerous small worm tubes in the sand and recently dead ?tellin valves. |

This was a dense extensive bed of 'clean' Zostera marina. Clearings where Zostera was sparse or absent were present. Few algae were mixed-in and Chorda filum was only frequent. Leaves of Zostera were colonised by rissoid gastropods and Musculus sp. and there were large numbers of Haustoriid amphipods swimming amongst the Zostera. Sediment sample 4 - consisted of soft sublittoral mud and muddy sand from 2m BCD. 34 species were found, mainly epifaunal species, particularly amphipods, small bivalves and the prosobranch mollusc Rissoa membranacea. Infauna were sparse and consisted almost entirely of the bivalve Mysella bidentata and indet. The community is present on mud or muddy sand at depths between about 0.5 and 2.5m BCD. Zostera plants are patchy in occurence and often have large numbers of Chorda filum mixed in. The small gastropod Rissoa membranacea is present in very large numbers on the leaves of the sea grass together with smaller numbers of the bivalve Musculus costulatus and in some areas, the top shell Gibbula cinerarea and the small bivalve Parvicardium exiguum. Two-spot gobies, Gobiusculus flavescens and the saithe Pollachius virens are present above and amongst the Zostera beds, 15 spined sticklebacks Spinachia spinachia are sometimes seen. Swarms of large, unidentified amphipods and mysid shrimps swim among the Zostera. Where sparse Zostera occurs, the sediment communities are similar to those in the surrounding areas of sediment. |
