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.

Sea turtles breeding along the Gulf Coast are among the species deemed most vulnerable to climate change and rising sea level, the U.S. Fish and Wildlife Service concluded in a new vulnerability assessment that looked at four Gulf ecosystems and 11 species dependent on them.
The ecosystems are mangrove, oyster reef, tidal emergent marsh and barrier islands. The species are roseate spoonbill, blue crab, clapper rail, mottled duck, spotted seatrout, eastern oyster, American oystercatcher, red drum, black skimmer, Kemp’s ridley sea turtle and Wilson’s plover.
