High Five to the RESTORE Council!

Posted On July 25, 2014 by

In order to successfully restore the Gulf of Mexico from the BP Deepwater Horizon oil disaster, Ocean Conservancy, as you may recall, has a tried-and-true Recipe for Restoration:

1 part science

1 part public engagement

1 part clear criteria for decision-making

We are so pleased today to see that the RESTORE Council is following our recipe for success. As the federal and state partnership charged with determining how billion of dollars in Clean Water Act fines will be spent, the RESTORE Council announced their plans today for receiving and evaluating proposals for Gulf restoration projects. This long-awaited announcement has been years in the making, and Ocean Conservancy has been one of the strongest supporters for a science-based platform for successful Gulf restoration. Thanks to the actions taken by the Council today, projects to restore the Gulf will be chosen based on merit, not on politics.

Fishermen and Scientists Work Together to Track Sick Fish

Posted On July 21, 2014 by

Fishermen are on the water every day, which means they are often the first to notice when something changes. After the BP Deepwater Horizon oil disaster, we heard reports from fishermen that they were catching more fish with lesions than they had ever seen before. Immediately after hearing these reports, Dr. Jim Cowan at LSU began investigating the frequency, location and cause of the reported lesions. Many other scientists have collected data on this same issue, and last week a group from the University of South Florida published the first round of results in a scientific journal.

Troubling News for Mahi-mahi in the Gulf

As we watched the BP Deepwater Horizon oil disaster unfold on beaches and in bays of the Gulf of Mexico four years ago, we wondered, too, about the impacts beyond what we could see on shore. Some of the answers to that troubling question are rolling in. We previously learned about damage to fish embryos, and the latest news involves mahi-mahi, or dolphinfish. These fast-growing, colorful predators are a favorite target of recreational fishermen and restaurant-goers alike across the Gulf, and despite their savage speed, it seems they could not outrun the impacts of BP’s oil.

A new study from the University of Miami last week demonstrated that even “relatively brief, low-level exposure to oil harms the swimming capabilities of mahi-mahi, and likely other large pelagic fish, during the early life stages.” And while it’s troubling to hear that oil reduces the fish’s ability to swim fast – a necessity for finding food and evading predators –the more disturbing revelation is how little oil exposure it takes to cause this damage to such an economically important fish.

Restoring Beyond the Shore is Critical to Gulf Recovery

Posted On April 20, 2014 by

Four years ago today, this image appeared on televisions around the world. And soon after that, we saw the 24-hour live feed of the well at the bottom of the Gulf, endlessly pouring gallon after gallon of oil into the water.

Almost immediately, the coastal impacts of the BP Deepwater Horizon oil disaster were easy to spot — oiled beaches, marshes, and pelicans. And now, four years later, we have both an opportunity and an obligation to restore the Gulf with the billions of dollars from BP. It’s easy to imagine how we would repair the coast — replant marsh grasses, rebuild barrier islands and restore oyster reefs.

Unfortunately, the damage that BP caused goes beyond what we can see from the seashore. We now know that dolphins in Louisiana are severely ill, deep-sea corals are covered in oil and BP oil can even give fish heart attacks.

But how do you restore the Gulf beyond the shore?

My Personal Journey from Despair to Hope Four Years After the BP Oil Disaster (Part 1)

Posted On April 17, 2014 by

Kara Lankford flies in a Black Hawk helicopter to assess damage done by the BP Deepwater Horizon oil disaster.

Four summers ago, I was in a Black Hawk helicopter overlooking the Alabama beaches, helplessly watching oil roll in from the spill on the Deepwater Horizon oil rig. I was working as a natural resource planner for Baldwin County on the Alabama Gulf Coast when Deepwater Horizon exploded, and the first reports of the tragic loss of life stopped me in my tracks. As the days went on, it was evident that this was not only a human tragedy but also a serious environmental disaster. As the oil continued to gush from the well, oil projection maps were published daily, and each day the oil grew closer to the Alabama coast. Suddenly this place where I had spent so many happy days was about to change, and change dramatically.

Interview with Marine Mammal Researcher Dr. Ruth H. Carmichael on the Stranding of Dolphins, Manatees and Whales

Posted On April 15, 2014 by

This blog is part of a series of interviews with scientists who are championing marine research in the Gulf of Mexico.

We know there was a very significant increase in the number of marine mammal strandings observed following the BP Deepwater Horizon oil disaster. Dr. Ruth H. Carmichael talks to Ocean Conservancy about her work to respond to strandings when they occur, collect data to better understand these strandings and put together public outreach programs to prevent them in the future.

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

Posted On April 8, 2014 by

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.
