Microbiology of subtidal sediments: Monitoring microbial populations. Restoration project 93047-2. Exxon Valdez oil spill restoration project final report
Following the Exxon Valdez oil spill in 1989, the authors measured numbers of hydrocarbon-degrading microorganisms 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 statistically significant higher values at the oiled sites than at reference sites. In the summer of 1993, the authors returned to ten study sites within Prince William Sound to monitor the changes in the numbers and activities of hydrocarbon-degrading microorganisms at these sites with time. In 1993 the numbers and activities of hydrocarbon-degrading microorganisms were generally very low at all sites although elevated populations and activities were measured in intertidal sub-surface samples at several sites (Northwest Bay, Herring Bay and Sleepy Bay) with observable sub-surface oiling.
