Implications for Spill Response
Our intent in creating this monitoring program was to study shoreline ecological recovery after an environmental disaster like the Exxon Valdez spill, and then to use those lessons as scientific guidance for what we do in future response actions. At this point in time, our task is incomplete. However, some of the findings have already changed the way we think about cleaning up oil spills. Some examples of what we have learned that may be important for spill response include the following:
- Using water to flush an oil-contaminated beach may also wash away fine-grained sediments and nutrients that small organisms need to successfully colonize; and it can take years for the fine sediment to return.
- Rocky rubble shores should be of high priority for protection and cleanup because of the potential for deep penetration and slow weathering.
Further Spill Response Implications
In addition to the points listed above, the following have further information available in this section of our site. |
- Hot-Water Washing More judiciousness in the use of aggressive cleanup methods, such as hot-water washing, would help to temper the severe effects we have observed in biological communities.
|
- Adult Clams Adult animals such as clams may survive in oil-contaminated beaches, but juveniles do less well.
|
- Oil Leaching Oil that penetrates deeply into beaches can remain relatively fresh for years and serve as a source of exposure to nearby animals.
|
- Berm Relocation After large-scale excavation or reworking of gravel beaches, it can take many years for the beach sediments to recover.
