| Abstract: | Three experimental ecosystems were employed to test the effect of Corexit 9527, with and without Prudhoe Bay crude oil, on the ecology of a temperate pelagic ecosystem. The results indicated that Corexit 9527 alone enhanced biological productivity without changing the structure of the ecosystem. The mixture of Corexit and crude oil caused a major change in the ecology of the ecosystem which resulted in large numbers of bacteria and zooflagellates, but a depression of all other zooplankton phyla. |
