THE AMOCO CADIZ OIL SPILL-LINES OF STUDY AND EARLY OBSERVATIONS

The French Ministry of Environment is sponsoring a long-term program to assess the ecological impact of the Amoco Cadiz oil spill on the marine environment. Nine French organizations, along with U.S. and Canadian agencies, are participating in a 3-yr program to monitor the chemical quality of the water, sediments, and marine organisms, study ecological effects and microbiological processes, and conduct toxicological research. Collective reports document the oil impact as follows: the fresh crude oil was rapidly dispersed by rough seas in the first fortnight, killing numerous marine organisms; the general spreading of the oil was controlled with all rocky and sandy shores facing the west progressively oiled; winds turned easterly; spring sand aeration in the upper part of the beaches with high tidal coefficient buried the heavy oil deposits to depths of 50-80 cm; low energy areas, Abers, Bay of Morlaix, and Lannion, were heavily polluted and will likely be polluted for long periods of time; and the resultant hydrocarbon levels in subtidal sediment in the Bay of Lannion and the Bay of Morlaix were 1%-2% at 8-30 m depth. Birds were directly affected with 4,000 dead birds collected. Algae seem to be in good physiological condition. The zooplankton were almost absent 1 mo after the spill, but were beginning to reappear the following month. The commercial fishing activity in the area was interrupted for only 1 mo. The oyster beds were highly polluted with 150-400 ppm total hydrocarbons and could not be used for several months.
