Very coarse sediment at 18 m bsl with polychaetes, molluscs and ophiuroids. Paraonis fulgens, Lumbrineris gracilis and Heteromastus filiformis were the most numerous polychaetes. Crustacea included a large number of ostracods; these were not found in significant numbers at any other station. Metaphoxus fultoni was the commonest amphipod. A large number of juvenile crabs which were found in one of the replicates probably indictaed a larval settlement. Some of the mollusc species found here, Emarginula reticulata, Acmaea virginia, and several chitons, were attched to large pieces of shell and stones in the bottom subtratum. Likewise the ophiuroid Ophiothrix fragilis is a species typically occurring mainly on hard bottoms and is often found in empty shells and amongst worm tubes.

Medium grained sediment at 33 m bsl with high spp numbers of polychaetes. The number of species was high with 54 species of polychaetes found. The small spionids Prionospio malmgreni and Polydora quadrilobata were the most numerous, together with Lunbrineris gracilis, Chaetozone setosa and Rhodine gracilior. Other polychaetes included the sphaerodorid Commensodorum commensalis and its commensal host Terebellides stroemi. Thyasira flexuosa, Abra spp and Chaetoderma nitidulum were the most frequent molluscs at this site.

Coarse and fine grained sediment at 24m bsl with polychaetes and a depleted crustacean fauna. Lumbrineris gracilis, Jasmineira caudata and Chaetozone setosa were the most common polychaetes, but many other species were almost as equally numerous. The crustacean fauna was depleted with only a few individuals of several species. Lepton nitidum was present suggesting a coarse grained sediment (see station 14). Other molluscs occurred in small numbers, many of them were juveniles.

Fine grained sediment at 27 m bsl with polychaetes. The most numerous polychaetes at this station were spionids, with quite large numbers of Prionospio malmgreni, also Paraonis fulgens, Chaetozone setosa, Rhodine gracilior and Jasmineira caudata. Large numbers of other species were also present giving a mean number of species for the three replicates of 71, the highest recorded from any of the stations. The crustacean fauna was more diverse than that at stations 14 and 15, but numbers of individuals were low. Thyasira flexuosa was the most common mollusc, with the caudofoveate Chaetoderma nitidulum being an important component of replicate 19/3. The specimens of Modiolarca tumida recorded from the latter replicate were commensal in two large specimens of Ascidia mentula.
