| 520 | |a"Assessing the environmental effects and impacts of oil spills is challenging, even when assessing impacts on highly visible top predators such as marine birds. The number of methods to assess the effects and impacts on marine birds from oil spills are limited, and require many assumptions, especially when pre-spill data are not available. In offshore environments the methods become even more constrained, because beached bird carcass surveys are not possible"--Executive summary, page 7. |
