Macrobenthic Communities of the Dam Neck Disposal Site.

Non-commercial benthos were sampled quarterly at four Dam Neck Extension stations in 1983-84 and once at five Dam Neck Interim stations in July 1984. Five replicate Shipek Grabs were taken at each station and sediment grain-size analysis was performed on grab sub-samples. Commercial benthos were sam...

Description
Summary:Non-commercial benthos were sampled quarterly at four Dam Neck Extension stations in 1983-84 and once at five Dam Neck Interim stations in July 1984. Five replicate Shipek Grabs were taken at each station and sediment grain-size analysis was performed on grab sub-samples. Commercial benthos were sampled seasonally on two occasions by three commercial dredge hauls at the Dam Neck Extension Site and by a single haul on one occasion at the Dam Neck Interim Site. The dredges yielded low abundances of species of limited commercial value. Sediment analysis revealed two potential groups of stations. However, results of dominance analysis, principal component analysis and discriminant analysis indicate that benthic infauna at Dam Neck are assemblages within a single sandy-substrate community with some micro-habitat specific variation.
