Based on oil fate modeling of the Deepwater Horizon spill through August 2010, during June and July ~89% surfaced, ~5% entered (by dissolving or as microdroplets) deep plume (>900 m), ~6% dissolved biodegraded between 900 m 40 m. Subsea dispersant application reduced surfacing by ~7% evaporation volatiles ~26%. By 2011, total oil, ~41% evaporated, ~15% was ashore in nearshore (<10 m) sediments,...
