Rocky coasts

Exposed, steep rocky coasts provide an ideal surface to which large quantities of oil can stick. They are fairly quickly cleaned by the mechanical effect of subsequent wave action, and therefore suffer relatively little from oil spills.

Rocky outcrops, which may be submersed at high tide or in heavy swell, can be more severely affected, especially if the outcrop contains rock pools rich in flora and fauna, where thick layers of oil are likely to accumulate.
