| Abstract: | Long term temporal variations in nematode and copepod densities were monitored in the upper and lower part of the Bay of Morlaix (West Channel), which was heavily contaminated by the 1978 Amoco Cadiz oil spill. Deseasonalization of abundance data allowed estimates to be made of the different components, namely the annual and seasonal trends and the residue. Reduced nematode abundance was long lasting in both types of sediment investigated: it appeared to be a gradual decrease in sublittoral sand but there was a dramatic reduction in estuarine mud 2 years after disturbance. Copepod variability, however, was related to seasonal factors. |
