Winter Survey Results
Benthos:
424 species in 14 phyla, with dominance by polychaete annelids (46.9%), crustaceans (18.2%) and bivalves (11.1%)
Average:
33.7 species/0.5m2,
449.8 ind/m2,
27.81 g/m2
Sediment:
fine with high (>70%) % silt clay;
mean TOM 5.45%

The recorded species belong to 16 taxonomic groups, including porifera, coelenterates, platyhelminthes, nemerteans, nematodes, annelids (polychaetes, oligochaetes), sipunculans, echiurans, molluscs (bivalves, gastropods), arthropods (crustaceans), bryozoans, phoronid, echinoderms, hemichordates, cephalochordate and osteichthyes (fish).
