Oil spill cleanup can involve a bunch of different tools, including floating barriers called booms, chemical dispersants and biological agents, and skimmers, which are boats that skim or scoop spilled oil off the water's surface.

溢可能涉及许多不同的工具，包括称为围栏的浮动屏障、化学分散剂和生物制剂，以及器，它们是从水面上去或舀出溢出的的船只。

And the Coast Guard admitted they can't account for a lot of oil. And that oil has been submerged in the Gulf because of the dispersants that were used. And then when Hurricane Isaac came around, it churned up that.

海岸警卫队承认他们无法解释大量石。由于使用了分散剂，这些石淹没在海湾中。然后当艾萨克飓风来临时，它搅动了一切。
