Following the Exxon Valdez oil spill in 1989, the authors measured numbers of hydrocarbon-degrading microoganisms and hydrocarbon mineralization potentials of microorganisms in oiled and unoiled surface sediments from the shore through 100 m depth offshore. The authors found both temporal and spatial variations in numbers and activity of hydrocarbon-degrading microorganisms with significant higher values at the oiled sites than at reference sites. The microbial data indicate mobilization between 1989 and 1990 of oil from the intertidal to surface sediments at 20, 40 and 100 m depths offshore.
