Es ist ein ökologisches Desaster. Denn eine neue Untersuchung zeigt: Das Öl aus der versunkenen Bohrinsel „Deepwater Horizon“ verseucht 3200 Quadratkilometer des Meeresbodens.

Am 20. April 2010 kommen bei einer Explosion auf der BP-Bohrinsel „Deepwater Horizon“ elf Menschen ums Leben. Alle Löschversuche scheitern, die Bohrinsel versinkt zwei Tage später im Meer. Mit verheerenden Folgen: Die Ölleitungen brechen auf, und Öl strömt ungehindert ins Meer. Erst Wochen später kann der Ausfluss gestoppt werden. Die Ölkatastrophe ist damit aber nicht vorbei. (more…)

Scientists Train the Next Generation on Oil Spill Research

As part of on-going research nearly four years after the Deepwater Horizon oil spill, scientists from the Woods Hole Oceanographic Institution (WHOI) will team up with a group of high school students in Florida to collect remnants of oil from Gulf Coast beaches this week.

Marine chemist Chris Reddy studies how the many compounds that compose petroleum hydrocarbon, or oil, behave and change over time after an oil spill. He and his researchers have collected and analyzed about 1,000 oil samples from the Gulf Coast since the Deepwater Horizon oil spill. (more…)

New Tool Available to Help Track Spilled Oil

Computer model can help with current, future clean-up efforts

St. Petersburg, Fla. – A newly developed computer model holds the promise of helping scientists track and predict where oil will go after a spill, sometimes years later. U.S. Geological Survey scientists developed the model as a way of tracking the movement of sand and oil found along the Gulf of Mexico since the Deepwater Horizon oil spill. The new tool can help guide clean-up efforts, and be used to aid the response to future oil spills. (more…)

Berkeley Lab scientists join an international collaboration to understand how archaea and bacteria work together deep in a cold sulfur spring

In the fall of 2010, Hoi-Ying Holman of the U.S. Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab) was approached by an international team researching a mysterious microbial community discovered deep in cold sulfur springs in southern Germany.

“They told me what they were doing and said, ‘We know what you contributed to the oil-spill research,’” recalls Holman, who heads the Chemical Ecology group in Berkeley Lab’s Earth Sciences Division. “They wondered if I could help them determine the biochemistry of their microbe samples.” (more…)

Scientists studying ocean currents and oil spills with large-scale experiment

Scientists are releasing hundreds of floating GPS devices into the Gulf of Mexico this week near the Deepwater Horizon site to study the role of ocean currents in oil spills. The experiment is the largest in scale of its kind, deploying 300 satellite-tracked, untethered buoys, called drifters, over the course of two and a half weeks.

“We’re trying to use the drifters as a simulation of an oil spill,” said Dennis Kirwan, Mary A.S. Lighthipe Professor of Marine Studies in the University of Delaware’s College of Earth, Ocean, and Environment. “This is a big event in oceanography.” (more…)

*Damaged deep-sea corals discovered months after Deepwater Horizon spill*

Scientists are reporting new evidence that the Deepwater Horizon oil spill has affected marine life in the Gulf of Mexico, this time species that live in dark ocean depths–deepwater corals.

The research used a range of underwater vehicles, including the submarine Alvin, to investigate the corals. The findings are published this week in the journal Proceedings of the National Academy of Sciences (PNAS). (more…)

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.

The study, “Chemical data quantify Deepwater Horizon hydrocarbon flow rate and environmental distribution,” is published online in the journal Proceedings of the National Academy of Sciences USA. (more…)

WHOI Website Will Take Viewers Deep into the Gulf

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 (https://divediscover.whoi.edu). (more…)
