ABSTRACT A diving survey was undertaken during August 1978 to ascertain the vertical and horizontal distribution of oil incorporated into bottom sediments of the bays of Morlaix and Lannion within the Amoco Cadiz spill site of Brittany, France. A total of 80 hand-held, 15-cm-long box cores was taken at 20 stations and analyzed for visual oil content and sedimentary characteristics. Chemical samples also were taken and now are being analyzed. Preliminary investigation revealed a significant amount of oil incorporated into the bottom sediments within both areas, although the mechanisms of deposition probably were different. Generally higher oil concentrations were found in muddy sediments, sediments containing Lithothamnium, and in samples taken offshore of heavily oiled beaches. The depth of oil penetration was usually less than 7 cm (possibly related to the depth of biological reworking), except in the more porous Lithothamnium sediments, or in those areas close to heavily oiled beaches. Hand-held box coring techniques are more advantageous than other shipboard methods in that the problems associated with grab sampling are avoided, and complete control is maintained over the sample at all times. In addition, direct observations of bottom sediment variability and visible oil accumulation can be made.
