Potential Threats from BP Oil to Bluefin and Yellowfin Tuna, Swordfish and Amberjack

Posted On April 8, 2014 by

© Cheryl Gerber

A new study published last month reveals how the 2010 BP Deepwater Horizon oil disaster likely caused life-threatening heart deformities and irregular function in the fish embryos of yellowfin tuna, bluefin tuna, amberjack and swordfish.

If you’re thinking that this sounds like another study we reported on last month, then you’re right. A number of different studies have been conducted on fish hearts, and each of them is an important piece of the puzzle that scientists are assembling to understand the impacts of the BP Deepwater Horizon oil disaster.

This latest study conducted by Dr. John Incardona and others clarifies how the oil from the BP oil disaster affects the embryos of large predatory fish living in the open ocean (or pelagic zone) of the Gulf of Mexico. Previous studies have determined that crude oil can be toxic or have delayed fatal effects on fish living in cold Arctic waters, such as pink salmon, or in warm freshwaters, such as zebrafish. We’ve also recently learned that Gulf killifish living in oiled areas of coastal Louisiana are suffering from deformed hearts and reduced chances of survival; another study helped us better understood the mechanism by which crude oil affects tuna hearts. Collectively, this research allowed scientists to make assumptions about how oil might affect fish living in the warm offshore waters of the Gulf.

Coast Guard Report Shows Shell Failed to Recognize Risk in the Arctic

This past Thursday, the U.S. Coast Guard released a report on its investigation into the grounding of Shell’s Arctic drilling rig Kulluk near Kodiak, Alaska on December 31, 2012. A tug lost control of the Kulluk in heavy weather on the way to Seattle after Shell’s failed attempt to drill for oil in the Arctic Ocean in 2012.

The Coast Guard report provides a detailed account of the events before the Kulluk ran aground and identifies a number of causal factors, including lack of experience in Alaska waters, failure to recognize risks, use of inadequate equipment, insufficient planning and preparedness and major problems with the primary towing vessel.

Ocean Acidification on the International Stage

Posted On April 4, 2014 by

The Intergovernmental Panel on Climate Change released a major report this week, addressing ocean acidification head on for the first time.  Ocean acidification is just as big a problem as severe storms, droughts, heat waves, wildfires, crop failures, disease and ocean circulation changes that are driven by global temperature rise. Just as with these other threats, the need for solutions is urgent. The good news is that there are already solutions at hand – all that’s needed is leaders willing to push for them.

Communities Come Together to Restore the Gulf

Posted On April 2, 2014 by

Great things happen when people come together and collaborate on a shared vision, especially when that shared vision is a healthier Gulf of Mexico. This notion rang true at a series of workshops Ocean Conservancy helped to coordinate in Mobile and Baldwin counties on the Alabama Gulf Coast. These “Community Conversations” were an opportunity to share information with and collect ideas from residents and business owners about the National Fish and Wildlife Foundation’s (NFWF) Gulf Environmental Benefit Fund.

As you might remember, NFWF established this fund with $2.544 billion from a settlement resolving the criminal cases against BP and Transocean as a result of the BP Deepwater Horizon oil disaster. Alabama will receive $356 million over the next five years to fund projects that benefit Alabama’s coastal and marine wildlife and habitats. Last fall, 22 projects were selected to restore and protect our natural resources around the Gulf Coast. Alabama received $12.6 million for three projects, which will restore oyster reefs and watersheds around Mobile Bay.

Honoring the Women Who Fight for Our Ocean (Part 3)

Posted On March 31, 2014 by

In honor of Women’s History Month, Ocean Conservancy will be publishing a three-part series highlighting some of the amazing women who study and protect our ocean. 

Dr. Anne Salomon

Dr. Anne Salomon grew up right by the sea in Vancouver, British Columbia, and it’s where she fell in love with the coast and the outdoors. She studied general biology at the landlocked campus of Queen’s University. She missed the coast and went west for her master’s degree at the University of British Columbia where she studied marine ecology. After completing that degree, Salomon was U.S. bound and received her Ph.D. in zoology.

Searching for a Missing Plane in an Ocean of Trash

The disappearance of Malaysia Airlines Flight 370 has scientists worldwide poring over blurry satellite images of remote portions of the Indian Ocean. While some of these photos may provide promising leads, others highlight a different problem: There is a lot of “stuff” in our ocean that doesn’t belong there.

Galveston Oil Spill Threatens Multibillion-dollar Investment in Gulf Wildlife

Posted On March 27, 2014 by

This week, as we recall the moment that the Exxon Valdez crashed into Bligh Reef just off the coast of a sleepy Alaska fishing town 25 years ago, a similar scene unfolds on the other side of the country. Under heavy fog, a barge traveling through Galveston Bay, Texas, collided with another ship and leaked an alarming amount of oil into the bay from its 168,000-gallon fuel tank. Due to bad weather, the oil is spreading quickly and has been spotted as far as 12 miles out in the Gulf of Mexico.

Response teams are busy trying to contain the oil on the water’s surface with boom and skimmers, but the damage has already been done. Spring is a crucial time for bird migrations in Texas, with an estimated 50,000 shorebirds and seabirds roosting at the Bolivar Flats Refuge only two miles from where the spill occurred. Our partners at Audubon and Galveston Bay Foundation are on the ground reporting a number of birds that have been found oiled. The surface oil also poses a threat to dolphins and turtles, which frequently surface in the bay. The endangered Kemp’s ridley sea turtles living in the Gulf nest almost exclusively on the coasts of Texas and Mexico.
