• Scientists: Oil spill's "grim reshuffle" of Gulf food web may destroy region's fishing industry

    The initial impact of the BP disaster on the maritime food chain in the Gulf are already apparent; scientists warn that if such impacts continue, they will result in a grim reshuffling of sea life that could over time cascade through the ecosystem and imperil the region’s multibillion-dollar fishing industry

  • Leaking well may be sealed ahead of schedule

    The Deepwater Horizon may be sealed a month or so ahead of schedule — during the second half of July rather than the second half of August — owing to three positive developments: one of two relief wells being drilled will be in a position to engage in “bottom kill” in several days; the containment ship Helix Producer, capable of capturing an additional 53,000 barrels of oil a day, is on station; BP is pressing ahead with plans to swap the current leaky containment cap with a new, no-leak, bolt-down cap

  • U.K. approves well-capping and containment study; new prevention, mitigation solutions sought

    In response to BP’s Gulf disaster, the U.K. offshore oil and gas advisory group charged its technical review group to proceed with developing new solutions for preventing or mitigating similar catastrophes in the future; over the past twenty years nearly 7,000 wells have been successfully drilled in the U.K. continental shelf

  • Louisiana, coastal scientists in bitter dispute over how to limit damage of oil spill

    Louisiana leaders, desperate to prevent oil from the hitting Barataria Bay, a vast estuary in southeast Louisiana that boasts one of the most productive fisheries in the country, want to build a rock dikes across several major tidal inlets between the bay and the Gulf of Mexico to block and then capture the oil; about 100,000 tons of rock began being loaded onto 75 barges on the Mississippi River for transport to the coast; scientists say the dikes would do irreversible damage to existing barrier islands and coastal wetlands, and the Army Corps of Engineers denied a permit for the project

  • U.S., U.K. military leaders address climate change's role as a global threat multiplier

    Conflict brought on by droughts, famine, and unwelcome migration are as old as history itself. Yet, a growing number of military analysts think that climate change will exacerbate these problems worldwide and are encouraging countries to prepare to maintain order even as shrinking resources make their citizens more desperate; Rear Admiral Neil Morisetti: “We see climate change as a threat multiplier, as a catalyst for conflict”

  • Australia could face climate refugees

    Australia could face a wave of climate refugees from neighboring Pacific islands unless rich nations help poorer countries with climate change, scientists warned; the 900 climate scientists gathered at a the conference heard specialists say that Australia is already experiencing the effects of climate change and is likely to be one of the most severely affected among developed countries

  • U.S. Navy blimp to help track oil flow in gulf

    A U.S. Navy blimp arrived in the Gulf of Mexico yesterday to help detect oil, direct skimmers, and search for threatened wildlife; the blimp can carry as many as ten crew members as it flies slowly over the region to track the direction of the oil flow and how it is washing ashore

  • New long-term threat from oil spill recognized: increasing ocean's arsenic levels

    Oil spills can increase levels of toxic arsenic in the ocean, creating an additional long-term threat to the marine ecosystem; sediments on the sea floor filter naturally occurring arsenic out of seawater, keeping the levels of arsenic low; oil spills clog up sediments on the ocean floor with oil, which prevents the sediments from bonding with arsenic and burying it safely underground with subsequent layers of sediment

  • Can microbes break down oil washed onto Gulf beaches?

    Nature provides its own methods for keeping sandy beaches clean: microbial communities which are native to the sands; researchers are studying whether native oil-eating bacteria that wash ashore with the crude are helping or hindering these native microbial communities

  • Second pipe may have crippled BP well's defenses

    The discovery of a second drill pipe joins a list of clues that is helping scientists understand the complexities of the Deepwater Horizon accident, and learn lessons which will inform changes in how deep-water drilling is conducted; evidence emerges that BP cut safety corners because the drilling fell behind schedule; one expert says: the accident “absolutely was preventable—[the rig lacked] “a regulatory presence onboard that said, “I don’t care how late it is, you do it right or you go home.”

  • UGI proposes innovative clean-up plan for Gulf

    BP’s oils spill now covers an area the size of Luxembourg; a U.K. clean-tech company joins with an Ohio-based partner to offer boat towing technology platforms specifically designed to remove the oil threatening the beaches of the Gulf of Mexico and the waters around the Deepwater Horizon well; a towed membrane acts like blotting paper in attracting oil that can then be released only by mechanical pressure

  • Cap temporarily removed from gushing well

    The lower marine riser package (LMRP) containment cap was taken off the failed Deepwater Horizon blowout preventer (BOP) earlier today after a vent on the cap accidentally got closed; it appears that a remotely operated vehicle accidentally bumped into the LMRP cap and closed a vent; the cap was taken off the well because with the vent closed, dangerous pressure was beginning to build up inside the well, raising the specter of another explosion, similar to the one on 20 April which destroyed the well

  • Bacteria will help keep CO2 safely sequestered

    With the world still heavily reliant on fossil fuels to meet its energy needs, carbon sequestration technologies could help reduce greenhouse gas emissions; one of the big challenges to making this a reality is ensuring that the CO2 stays locked away underground; the humble Bacillus subtilis bacteria will help

  • BP's first relief well has now reached 4,200 meters, with 1,300 meters to go

    BP has been drilling two relief wells in the Gulf of Mexico in an effort to stem the flow of oil from the stricken Deepwater Horizon; a relief well aims to bisect the original well casing, enabling engineers to pump in mud and concrete to seal up the well; drilling into an 18-centimeter-wide cylinder 5,500 meters below the sea floor is not easy

  • Balls of steel: A scientists proposes dropping steel balls into well to stop leak

    Willard Wattenburg made a name for himself by directing the capping of the more than 500 hundred burning oil wells in Kuwait after the Gulf War in 1991; he now proposes dropping steel balls of different sizes into the gushing well; if the steel balls are big enough in diameter, their weight will pull them downward even through the upward-rushing torrent of oil and gas; they will settle into the well at some deep level and begin to clog it
