Three Historic Blowouts - 0 views

    Three Historic Blowouts 1. Lauren Schenkman Figure Mexico 1979 "CREDIT: NOAA" The decade from 1969 to 1979 witnessed three massive spills from offshore oil wells around the world. Here is how they compare in size and impact. IXTOC 1 The biggest well-related spill was triggered on 3 June 1979, when a lack of drilling mud allowed oil and gas to shoot up through the 3.6-km-deep IXTOC 1 exploratory well, about 80 km offshore in the southern Gulf of Mexico. The initial daily outflow of 30,000 barrels of oil was eventually reduced to 10,000 barrels. The well was finally capped more than 9 months later. Mexico's state-owned oil company, PEMEX, treated the approximately 3.5-million-barrel spill with dispersants. U.S. officials had a 2-month head start to reduce impacts to the Texas coastline. Figure North Sea 1977 "CREDIT: WALLY FONG/AP PHOTO" Ekofisk The first major spill in the North Sea resulted in the release of 202,000 barrels of oil about 250 km off the coast of Norway. The 22 April 1977 blowout caused oil to gush from an open pipe 20 m above the sea surface. The well was capped after a week. Between 30% and 40% of the spill evaporated almost immediately. Rough waters broke up the slick before it reached shore. Figure Santa Barbara 1969 "CREDIT: BETTMANN/CORBIS" Santa Barbara A blown well 1 km below the sea floor and 9 km off the coast of Santa Barbara, California, spewed out a total of 100,000 barrels of oil. The initial eruption occurred on 28 January 1969, and the well was capped by mud and cement on 7 February, but the pressure forced oil through sea floor fissures until December. The oil contaminated 65 km of coastline. At least 3700 birds are known to have died, and commercial fishing in the area was closed until April.

Will Deepwater Horizon Set a New Standard for Catastrophe? - 0 views

    "Will Deepwater Horizon Set a New Standard for Catastrophe? 1. Richard Kerr, 2. Eli Kintisch and 3. Erik Stokstad Summary The fiery destruction of an oil drilling platform in the Gulf of Mexico on 20 April may have triggered one of the worst environmental disasters in U.S. history. The impact of the crisis, which began with the deaths of 11 workers and then simmered for several days before an expanding oil slick grabbed worldwide attention, promises to test the federal government's ability to protect habitat, wildlife, and the economic well-being of a four-state region on a scale never before imagined.

Mermaid opens prospect of cleaner seas with pollution early warning system - 0 views

  •  
    ScienceDaily (July 9, 2010) - Alarm at the massive oil plume in the Gulf of Mexico emphasizes the problem of marine pollution and how difficult it is to evaluate. Thanks to a EUREKA project, another heavily polluted maritime ecosystem, the European North Sea, has been for more than 20 years a test-bed for a highly advanced early-warning system for all types of pollution. This development is now aiding marine authorities around the world to keep seas clean.

Gulf Drilling Disaster Triggers Scrutiny of Mediterranean Oil Rush - 0 views

    "Oil Exploration Oil Exploration Gulf Drilling Disaster Triggers Scrutiny of Mediterranean Oil Rush 1. Laura Margottini* A rush to find and extract oil in the Mediterranean Sea is threatening one of the planet's marine biodiversity hot spots, scientists warn. PANTELLERIA, ITALY-This tiny speck in the Mediterranean, home to a few thousand people, seems like one of the most tranquil places in the world. But looks are deceptive. Pantelleria, in the Strait of Sicily halfway between Palermo and Tunis, is close to one of the world's busiest shipping lanes, and of late, its waters have also become the center of a new oil rush. Attracted by Italy's easygoing drilling regulations and low tax on oil extraction, dozens of companies have new plans for exploration and drilling in this part of the Mediterranean Sea. At a recent meeting here,* however, scientists, conservationists, and environmental activists warned that such efforts put several important biodiversity hot spots in danger. An oil disaster like the Deepwater Horizon explosion, which sent oil gushing into the Gulf of Mexico for months, could easily ruin the Mediterranean ecology for a century or longer, some said. The Italian government has recently issued 66 permissions for drilling around its coasts and 25 concessions for exploration. Another 67 applications for exploration are under review. "Italy now represents the region that holds the most exciting and significant long-term opportunities," one company, Northern Petroleum, says on its Web site. The Strait of Sicily is the center of attention, but other biodiversity hot spots, such as the Tremiti Islands in the Adriatic Sea, could soon be explored as well. Italy isn't alone. Tunisia, for example, has granted concessions for oil exploration for most of its Mediterranean waters, without much political opposition. But the areas coveted by oil companies are ecological treasures, researchers and groups such as Greenpeace Italy stress. Last year, the Uni
