Prospects for new executive order are unclear and legal challenges await
Donald Trump’s retro administration is taking another step backward by attempting to re-open parts of the Atlantic, Arctic and Pacific oceans, as well as the Eastern Gulf of Mexico, for offshore oil drilling. The executive order announced by Interior Secretary Ryan Zinke requires the the department to conduct a five-year review of the existing program for oil and gas development on the Outer Continental Shelf.
That could potentially reverse actions taken under President Obama to restrict some offshore drilling, although the feds will have to show scientifically that new offshore drilling is justified economically and can be done without harm to the environment. Legal challenges would also raised to any new proposals to lease areas off the coasts of the U.S. More drilling would also add more heat-trapping greenhouse gas pollution to the atmosphere.

New data help show how long impacts will linger on seafloor, where pollutants get into the foodchain
Fall-out from the 2010 Deepwater Horizon oil disaster contaminated more 1,000 square miles of the Gulf of Mexico’s seafloor, but the exact long-term ecological effects are still unknown, said a group of scientists who are tracking 125 major petroleum hydrocarbons settled to the deep ocean floor when the failed Macondo well discharged 160 million gallons of crude oil into the water.
Oil washed toward shore after the 2010 Deepwater Horizon disaster is a big factor in coastal erosion rates, according to scientists with NASA and the U.S. Geologicial Survey who tracked the changes along the Gulf of Mexico. Their research shows a pattern of dramatic, widespread shoreline loss” along the Louisiana’s coast in Barataria Bay, located on the western side of the Mississippi River Delta.
Oil and gas exploration would have widespread effects on marine mammals
Conservation advocates have long been saying that blasting the Gulf of Mexico with seismic airguns to find more oil and gas beneath the seafloor would result in unacceptable harm to marine mammals and other marine life, and a new draft environmental study by the Bureau of Ocean Energy Management seems to confirm those concerns.
The study was completed under the terms of a court-ordered settlement of a lawsuit brought by environmental groups. It shows that the blasting would have widespread impacts on marine life, including injuries to endangered sperm whales and Bryde’s whales. The draft report outlines possible mitigation measures, including closure areas where seismic blasting would be banned, and reductions in the amount of activity permissible each year.

In findings from new study released this week, researchers from the University of California, Riverside and the University of Miami Rosenstiel School of Marine and Atmospheric Science reported that old, weathered oil from the spill is even more toxic than fresh crude oil. Ultraviolet light changes changes the chemistry of the oil, the scientists said, further threatening numerous commercially and ecologically important fishes.
Lung abnormalities found in 88% of perinatal dolphins in spill zone
Scientists studying the aftermath of the 2010 Deepwater Horizon oil disaster in the Gulf of Mexico say results of a recently completed four-year study of dolphin strandings confirm that the spill took a toll on marine mammals.
Grassroots groups open new front in the battle against fossil fuels and climate change
While conservation groups celebrated the Obama administration’s recent decision to temporarily bar new oil and gas leases off the Atlantic Coast, activists aren’t finished battling the fossil fuel juggernaut quite yet.
Opening a new front in the climate war, hundreds of Gulf Coast residents are joining forces with local and national environmental and social justice groups to oppose a federal offshore fossil fuel lease sale in the Gulf of Mexico — a region that has a long economic dependence on fossil fuel exploitation, so it’s unclear if the protest movement will resonate with a majority of locals.
