Exxon valdez why did the oil float




















Some injured species are still recovering. The people and economies of communities in the oil spill region suffered in the months and years following the spill. Commercial fishing and tourism were especially affected.

The first three days after the Exxon Valdez oil spill afforded nearly ideal weather for oil recovery. Seas and winds were calm. Two decades later, they agree on one thing with regard to Exxon Valdez: the first three days were lost. The chemicals, which are being used widely in the current Gulf spill crisis, break oil into fine droplets so that it can be absorbed into the water and degrade naturally.

Warm water and wave action speed the mixing and energy. Kelso remembers the early days differently, though his conclusion is the same. Exxon, which had relied on an unreliable contractor to prepare for the spill, was scrambling in the first few days. Conflicts over dispersants were one of the first between the main players in the cleanup -- state authorities like Kelso, Exxon leaders like Maki, and the federal government, including John Robinson, the chief scientist at the spill for the National Oceanic and Atmospheric Administration.

Robinson remembers two years of animosity and contention, a management problem that contributed to the oil spill issue -- and which was dealt with directly by legislation the following year that gave the federal government clear authority to step in and take charge of a spill response, as it has done on the Gulf Coast.

The storm which swept through three days after the crash totally changed the game, making it a desperate attempt to keep oil away from sensitive areas and muster resources. An obvious solution to too much oil is to send it up in flames. Some 15, gallons burned in about 75 minutes in one attempt the day after the spill.

But others proved futile. Little seemed to be happening the day after the spill, and Exxon panicked at the lack of clear action. There was no incident command system, the standard hierarchy that is used for responses to natural disasters and is now automatically activated to respond to oil spills.

Exxon coordinated with the group, and Kelso says it shamed the oil giant into action. The oil kept spreading. In four days it was 37 miles from the spill site. In two weeks it was miles. By day 56, a sheen of crude stretched miles. But two months in, guerrilla warfare had turned into a corporate campaign. Exxon had mobilized in full. Some 11, workers were washing rocks, first with rags and then with power hoses. The main plan was to float the oil off the beaches.

Since oil floats, flooded beaches would shed the oil, which could be caught at the waterline. It was more than a big effort though. It was a big mistake, Robinson said. Nine strips of beach were left untouched as an experiment, and those nine beaches look better today than the swept ones, where whatever was alive was cooked to death in superhot water.

Maki, the Exxon scientist, disagrees. Exxon also put fertilizer on beaches far and wide, calculating that naturally existing microbes that eat naturally seeping hydrocarbons would multiply with the fertilizer and munch up the oil, which many said was indeed the case.
