Natural Wear of Oil on Rocky Shores
One year of erosional processes on oil on four different rocky shores in the northern archipelago of Stockholm has been studied. All the shores face north-east, are differently exposed to waves and drift ice and their slope is either flat or steep. Spots of heavy fuel oil (No 5) were painted at different levels above the water's edge. After twelve months of wearing, the two highly exposed rocks were practically clean from oil between the water line and the five metre level. Significant wearing was noticeable up to the half-meter level on the low exposed and flat sloping rock. The rock with a steep slope were clean from oil only at the water's edge. Due to the high cost of substantial shore-cleaning operations, the National Swedish Board of Rescue and Fire Services recommended that no major efforts to clean up all the oil should be made on shores that are not ecologically or socio-economically important. Results from this study prove that natural erosional processes can be sufficient to remove oil from certain levels on rocky shores in a relatively short time (less than a year). Recommendations are presented on this basis, on which levels above the water's edge that can be excluded from major shore-cleaning operations, even on rocks that are ecologically or socio-economically important.
