The Deepwater Horizon oil spill in the Gulf of Mexico created large amounts of sea snot. Scientists are not sure how exactly the spill caused so much sea snot to form, but one theory asserts that the sea snot could have been the result of a massive kill of microscopic marine life creating a "blizzard" of marine snow. Scientists worry that the mass of sea snot could pose a biohazard to surviving marine life in the area. It is widely believed that the sea snot left by the spill directly resulted in the loss of sea life in the Gulf of Mexico, as evidenced by a dead field of deepwater coral 11 kilometers from the Deepwater Horizon station.
