It was eventually leased to BP and was involved in. The explosion on BP ’s Deepwater Horizon rig on 20 April 2010 caused the biggest oil spill in US history. However, because of its location, timing, and the ensuing oil slick, it remains the most well-known offshore disaster to date. “Marine snow,” as experts call this feast for deep sea scavengers, soon became “marine oil snow” after the spill, which introduced petroleum into the food web for deep-sea corals, squid, fish, sharks, and countless other creatures-possibly including some species that humans eat. The Deepwater Horizon was a semi-submersible offshore oil rig built in 2001 and owned by Transocean. The Deepwater Horizon incident killed 11 rig workers, but remains far less lethal than most offshore disasters. As some oil sank toward the ocean’s depths, it intermixed with the blend of excrement, food scraps, and mucus that rains gently and constantly from the surface toward the deep ocean floor. Living creatures also shaped the oil’s fate.
Even a decade later, swaths of the ubiquitously oil-tainted wetlands along the Gulf Coast shoreline contain chemical markers that implicate the Deepwater Horizon spill specifically as their originator. Despite the intense cleanup efforts along the coastline, a lot of the oil that reached the shore was widely spread by the tides through coastal marshes. The easiest oil to track may be the stuff that washed ashore, mainly as a light oil-mousse. They are still unsure how much of the oil that reached the ocean’s surface evaporated or volatilized into chemicals light enough to float. Farrington’s team notes that photo-oxidation “had been downplayed for decades” in research on oil spills. It was able to accommodate up to 130 people, but at the time of the incident, there was a crew of 126 people.
The rig was designed for operations in water depths of up to 8,000 feet with a maximum drill depth of 30,000 feet. The accident resulted in the deaths of 11 workers and caused a massive, ongoing oil. The Deepwater Horizon was built by Hyundai Heavy Industries Shipyard in South Korea in 2001. Scientists were shocked to learn that so much oil had been transfigured by sunlight. On April 20, 2010, a sudden explosion and fire occurred on the oil rig.
Scientists were shocked to learn that so much oil had been transfigured by sunlight.īefore reaching its final destinations, much of the spill at the surface was chemically transformed by exposure to sunlight into an even broader range of oily (and also airborne) compounds.
