Figure 1.
Representative photographs of shoreline oiling conditions.
Sand beaches: A. Small surface residue balls in the supratidal zone (scale is 15 cm); B. Buried oil patties; C. Surface residue balls in the intertidal zone that are angular, indicating that they were eroded from adjacent oil residue mats; D. Intertidal oil residue mats at the toe of the beach. Marshes: E. Heavily oiled wrack at the high-water line and oiled mat of laid-over vegetation; F. Thick (>1 cm) emulsified oil under the laid-over vegetation mats; G. Oil/shell incipient asphalt pavement on the marsh platform; H. Oiled Phragmites along the Mississippi River delta.
