| Abstract: | As part of a planning study of improvements to the navigation channels in Boston Harbor, Massachusetts (USA) biological and chemical composition were determined. During 1985 and 1986, sampling of the sediments and water column took place to understand existing conditions. These sampling efforts involved 21 sediment chemistry stations, 13 benthic infaunal stations, 6 otter trawl and gill net stations. The chemical determinations show high levels of contaminations in the inner channels. The benthic organisms react to this substrate chemical stress and a seasonal oxygen depletion with episodes of tolerance and defaunation. The finfish species follow a similar pattern as the infaunal community. |
