Four WHOI Scientists Contribute to Comprehensive Picture of the Fate of Oil from Deepwater Horizon Spill
A new study provides a composite picture of the environmental distribution of oil and gas from the 2010 Deepwater Horizon spill in the Gulf of Mexico. It amasses a vast collection of available atmospheric, surface and subsurface chemical data to assemble a "mass balance" of how much oil and gas was released, where it went and the chemical makeup of the compounds that remained in the air, on the surface, and in the deep water.
Researchers Assess Radioactivity Released to the Ocean from the Fukushima Dai-Ichi Nuclear Power Facility
The impact on the ocean of releases of radioactivity from the Fukushima nuclear power plants remains unclear. But a new study by U.S. and Japanese researchers analyzes the levels of radioactivity discharged from the facility in the first four months after the accident and draws some basic conclusions about the history of contaminant releases to the ocean.
In a detailed assessment of the Deepwater Horizon oil spill, researchers led by a team from the Woods Hole Oceanographic Institution (WHOI) have determined that the blown-out Macondo well released oil at a rate of about 57,000 barrels a day, totaling approximately 5 million barrels of oil released from the well between April 20 and July 15, 2010, when the leak was capped. In addition, the well released some 100 million standard cubic feet per day of natural gas.
In the first published study to explain the role of microbes in breaking down the oil slick on the surface of the Gulf of Mexico, Woods Hole Oceanographic Institution (WHOI) researchers have come up with answers that represent both surprisingly good news and a head-scratching mystery.
Taking another major step in sleuthing the 2010 Deepwater Horizon oil spill, a research team led by the Woods Hole Oceanographic Institution (WHOI) has determined what chemicals were contained in a deep, hydrocarbon-containing plume at least 22 miles long that WHOI scientists mapped and sampled last summer in the Gulf of Mexico, a residue of the Deepwater Horizon oil spill.
Japan’s recent magnitude 9.0 earthquake, which triggered a devastating tsunami, relieved stress along part of the quake fault but also has contributed to the build up of stress in other areas, putting some of the country at risk for up to years of sizeable aftershocks and perhaps new main shocks, scientists say.
One year after the explosion of the Deepwater Horizon drilling platform in the northern Gulf of Mexico, the Woods Hole Oceanographic Institution (WHOI) is unveiling a new multimedia website, Science in a Time of Crisis.
While Japan’s 9.0-magnitude earthquake and accompanying tsunami represent a devastating natural disaster for the country’s residents, scientists should also seize upon the massive temblor as an important learning tool for future quakes around the world, including the Pacific Northwest coast of the United States, according to experts from the Woods Hole Oceanographic Institution (WHOI).
To combat last year’s Deepwater Horizon oil spill, nearly 800,000 gallons of chemical dispersant were injected directly into the oil and gas flow coming out of the wellhead nearly one mile deep in the Gulf of Mexico. Now, as scientists begin to assess how well the strategy worked at breaking up oil droplets, Woods Hole Oceanographic Institution (WHOI) chemist Elizabeth B. Kujawinski and her colleagues report that a major component of the dispersant itself was contained within an oil-gas-laden plume in the deep ocean and had still not degraded some three months after it was applied.
The U.S. National Deep Submergence Facility has had a growing and important role in the ocean science community’s response to the 2010 Deepwater Horizon oil spill in the Gulf of Mexico. With the recent R/V Atlantis/Alvin expedition (Nov. 8 – Dec. 3), now each of the three NDSF vehicles has been employed in the Gulf, to characterize the plume, collect samples, and map and explore the seafloor for signs of the spill’s impact.
Right now, it looks a little like one of those plastic containers you might fill with gasoline when your car has run dry. But Scott Gallager is not headed to the nearest Mobil station. The Woods Hole Oceanographic Institution (WHOI) biologist has other, grander plans for his revolutionary Swimming Behavioral Spectrophotometer (SBS), which employs one-celled protozoa to detect toxins in water sources.
It may take years before scientists determine the full impact of the 2010 Deepwater Horizon oil spill in the Gulf of Mexico. But, utilizing the human-occupied submersible Alvin and the autonomous underwater vehicle (AUV) Sentry, researchers are about to investigate—and view first-hand—the possible effects of the spill at the bottom of the Gulf. And, from Dec. 6-14, the mission will be relayed to the public as it happens on the Woods Hole Oceanographic Institution’s (WHOI) Dive and Discover website (http://divediscover.whoi.edu).
Despite growing awareness of the problem of plastic pollution in the world’s oceans, little solid scientific information existed to illustrate the nature and scope of the issue. This week, a team of researchers from Sea Education Association (SEA), Woods Hole Oceanographic Institution (WHOI), and the University of Hawaii (UH) published a study of plastic marine debris based on data collected over 22 years by undergraduate students in the latest issue of the journal Science.
Scientists at the Woods Hole Oceanographic Institution (WHOI) detected and characterized a plume of hydrocarbons that is at least 22 miles long and more than 3,000 feet below the surface of the Gulf of Mexico, a residue of the BP Deepwater Horizon oil spill. The work presents a forensic snapshot of the plume characteristics in June and is reported in a study appearing in the Aug. 19 issue of the journal Science.
A multidisciplinary team of investigators from Woods Hole Oceanographic Institution embarked June 17 for a twelve-day research effort in the Gulf of Mexico aboard the RV Endeavor, conducting three simultaneous projects funded through the National Science Foundation (NSF) “RAPID” program. The projects aim to locate, map, and characterize subsurface oil plumes extending from the Deepwater Horizon well head using novel technology and the latest in biogeochemical techniques.
On June 1, 2010, members of the staff of the Woods Hole Oceanographic Institution (WHOI) participated in a meeting at the Environmental Protection Agency headquarters in Washington, D.C., to consider possible alternative solutions to capping or controlling the flow of oil from the Deepwater Horizon well in the Gulf of Mexico. The conclusions and recommendations of the Deep Ocean Task Force, the ad hoc group initiated and convened by director James Cameron, are now available online.
The Woods Hole Oceanographic Institution (WHOI) is partnering with two Louisiana institutions to determine the myriad impacts of the Deepwater Horizon oil discharge into the Gulf of Mexico and to devise and implement possible solutions to the disaster.
Sea Education Association (SEA) is preparing to conduct the first-ever research expedition dedicated solely to examining the accumulation of plastic marine debris in the North Atlantic Ocean. The expedition is funded by the National Fish and Wildlife Foundation (NFWF) and the National Oceanic and Atmospheric Administration (NOAA) Marine Debris Program, and is in collaboration with the Woods Hole Oceanographic Institution and Woods Hole Sea Grant.
The most extensive study of pollutants in marine mammals’ brains reveals that these animals are exposed to a hazardous cocktail of pesticides such as DDTs and PCBs, as well as emerging contaminants such as brominated flame retardants.
A new study by researchers at Woods Hole Oceanographic Institution (WHOI) and the University of California, Santa Barbara (UCSB) is the first to quantify the amount of oil residue in seafloor sediments that result from natural petroleum seeps off Santa Barbara, California.
