BP has reached a $7.8-billion settlement with thousands of people affected by the 2010 Gulf of Mexico oil spill. Read more»

The Deepwater Horizon oil drilling rig burns at the BP-Macondo well June 22 in the Gulf of Mexico.

The chief regulator of offshore drilling tried to suggest to the Senate this week that the Obama administration has been issuing permits almost as quickly as before the BP oil disaster, but a review has shown that's not true. Read more»

Aerial view of the BP oil spill site off the coast of Houma, La., on July 13, 2010.

The oil spill that was once expected to bring economic ruin to the Gulf Coast appears to have delivered something entirely different: a gusher of money. Some profiteered by charging BP outrageous rates for cleanup. Others profited from claims money, but some hurt by the spill ended up getting comparatively little. Read more»

After the blowout of the Deepwater Horizon well triggered the largest oil spill in United States history, BP vowed to "Make it Right" for Gulf Coast residents affected by the spill. One of the central pieces of BP's program to make amends was to create a claims system — as required under federal law — to compensate individuals and businesses that lost money as a result of the spill.

In the name of job creation and clean energy, the Obama administration has doled out billions of dollars in stimulus money to some of the nation’s biggest polluters and granted them sweeping exemptions from the most basic form of environmental oversight, a Center for Public Integrity investigation has found.

During the Deepwater Horizon incident, BP showed the world that they were willing to spin the story whichever direction would make them seem concerned or made the disaster seem, well, less disastrous. Just be glad they don't own any mine shafts in Chile. Read more» 1

As part of the Shoreline Cleanup and Assessment Teams working on the Deepwater Horizon oil spill, staff of the Department of Environmental Quality documented heavy oil impacts in Bay Jimmy and Barataria Bay last week in Louisiana. According to reports compiled by the Louisiana National Guard, on Monday, Tuesday and Wednesday of last week, skimming operations in Louisiana collected 18,849 gallons of oil and 1,704 cubic yards of oily debris in Jefferson and Plaquemines parishes.

BP announced on Sunday that its ruptured well in the Gulf has at last been sealed, but the long-term environmental effects of the disaster remain unclear. Earlier this month, scientists discovered a thick layer of oil on the floor of the Gulf. Oil is continuing to show up on shorelines, and large quantities have been discovered under the sand.

Scientists conducting research in the Gulf have found a thick layer of oily sediment on the ocean floor stretching for miles. Read more»

Earlier this week, major news outlets ran with headlines about how a new microbe has been found eating up BP’s oil, and how microbes have degraded the hydrocarbons so efficiently that the vast plumes of oil in the Gulf are now undetectable. No joke. Read more» 1

Preliminary tests show that a lack of oxygen in part of the Gulf of Mexico caused thousands of fish to die, according to Louisiana authorities quoted by the Los Angeles Times. Read more»

Just how much of the oil spilled in the Gulf is still there? Depends on what the meaning of "is" is. NOAA is hedging some of its estimates, and not in a good way. About three-quarters of the oil that spilled into the Gulf from BP’s ruptured well is still in the environment. Read more»

An oil spill notice on Pensacola Beach, Florida, July 9.

A decade-old environmental assessment by offshore drilling regulators called for more research on Corexit dispersant, warned that deepwater spills were difficult to stop, and cautioned that such spills could "permanently cover water bottoms and wetlands." Read more»

BP appears to be delaying decisions about the validity of many claims for damages from the Gulf oil spill, leaving claimants frustrated by bureaucratic obstacles and confusing requests for more documentation. Read more»

It's Day 101 of the BP oil disaster in the Gulf, and you might be feeling pretty hopeful that soon enough, you won't have to think about oil spills for a while. Not so fast. On Tuesday, another spill was detected in the Gulf - the result of a boat's colliding with an out-of-use wellhead in Barataria Bay. Read more»

Oil from the damaged Deepwater Horizon oil well lingered off the Mississippi Delta on July 4, 2010. The Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Terra captured this natural-color image the same day. The oil appears as an uneven light gray shape east-southeast of the Mississippi Delta. The oil was visible to MODIS on July 4 thanks to sunglint. Oil smoothes the surface of the water, making it a better mirror of sunlight. As a result, close to the Sun’s reflection, the oil is brighter than surrounding water. This is especially true between the Mississippi Delta and the Deepwater Horizon location. East of the rig, however, sunglint lightens most of the water, making it more difficult to distinguish oil from oil-free water.

Scientists from the University of South Florida announced on Friday that they have "definitively connected" the underwater oil plumes to BP's ruptured and still slightly leaking well in the Gulf. Read more»
