EFFECT OF COASTAL PROCESSES ON THE DISTRIBUTION AND PERSISTENCE OF OIL SPILLED BY THE AMOCO CADIZ - PRELIMINARY CONCLUSIONS

The section of North Brittany contaminated by the Amoco Cadiz oil spill (Mar. 17, 1978) is a low-lying ria coastline dominated by dynamic processes favorable for the rapid dispersion of the oil. Aerial and ground surveys were made of the impacted area on Mar. 19-Apr. 2, and Apr. 20-28, 1978, to detail the distribution and persistence of oil along the shoreline. Oil deposition on the shoreline was primarily controlled by local geomorphology, e.g., rocky headlands, tombolos, crenulate bays, etc., and wind-driven currents. About 62,000 t of oil were spread along 123 km of coastline and offshore rocks during the 1st study, whereas during the 2nd study, oil was distributed along 375 km of shoreline and offshore rocks due to a shift in wind direction. However, the calculated quantity of oil was reduced by 85% to 9,200 t. This study supports a previously developed oil spill vulnerability index which clasifies shorelines on a scale of 1-10 as to the potential longevity of oil after an oil spill.
