Scientists Discover How BP Oil Affects Tuna Hearts

Posted On February 24, 2014 by

During the spring and summer of 2010, the BP Deepwater Horizon disaster released over 4 million barrels of crude oil into the Gulf of Mexico. This was an unprecedented amount of toxic material discharged into the Gulf, and scientists have been researching its impacts on marine and coastal wildlife ever since. One of the species of concern is the imperiled Atlantic bluefin tuna, which was spawning at the time and location of the BP disaster.

In a new study, scientists from Stanford University and the National Oceanic Atmospheric Administration (NOAA) discovered that crude oil, specifically polycyclic aromatic hydrocarbons (PAHs), disrupts the cellular pathway that allows juvenile bluefin and yellowfin tuna heart cells to beat effectively. This causes a slowed heart rate, reduced ability of muscular heart tissue to contract, and irregular heartbeats that can lead to cardiac arrest and death.

Crude oil is known to be toxic to the developing hearts of fish embryos and larvae, reducing the likelihood that those fish will survive. But until now, the details of how crude oil harmed fish hearts were unclear.

Misguided Lawsuit Threatens the Chesapeake Bay’s Recovery

Posted On February 13, 2014 by

Terrapin Beach Park in Stevenson, Maryland

There was a time when the water of Chesapeake Bay would appear to boil, but it was actually millions of oysters ejecting filtered water. The bay’s waters, the old timers tell us, were crystal clear. But agricultural run-off and untreated wastewater flowed into the Chesapeake for years, fouling the water and making our nation’s largest estuary a shadow of its former self.

In 2009, the U.S. Environmental Protection Agency (EPA) organized the cleanup efforts of six states within the bay’s watershed, including Maryland, Virginia, Delaware, Pennsylvania, New York, West Virginia and the District of Columbia. The efforts to limit pollution going into the bay included improving municipal wastewater treatment systems (known as point source pollution) and reducing agricultural runoff (known as nonpoint source pollution). Plans were in place, actions were being taken, and traction was being made.

Western Australia Shark Cull

Many species of sharks and rays around the world are in trouble, and current events in Australia remind us of that. The government of Western Australia is presently implementing a controversial “shark cull” policy in response to recent highly publicized shark attacks near Western Australian beaches. The policy consists of deploying baited hooks about a mile off of various Western Australian beaches, aimed specifically at catching large sharks. Any shark larger than 10 feet is viewed as a threat to public safety and is to be “humanely” killed; the main targets of the cull are tiger sharks, bull sharks and great white sharks. Great white sharks are a protected species in Australia, and state authorities were given a special exemption from Australia’s Environment Protection and Biodiversity Conservation Act to be able to kill them. The shark cull is a pilot program. If it were to continue after the April 30 trial period ends, there would have to be a full environmental act assessment.

Q&A with Sarah Cooley, Ocean Conservancy’s New Science Outreach Manager

Posted On February 8, 2014 by

Sarah Cooley, Ph.D. joined Ocean Conservancy as a Science Outreach Manager in the Ocean Acidification program in January. Previously, she was a research scientist at Woods Hole Oceanographic Institution in Woods Hole, Massachusetts.

Why did you become a scientist?

I always really liked science, and most of it just made sense to me. In college, I started feeling like there was always one more interesting science class over the horizon, so I decided to major in chemistry. Four years later, I still wanted to know more, but I wasn’t ready to face the real world, so I went to graduate school. I studied marine chemistry because I love the ocean and there seemed to be plenty of discoveries left to be made in that field.

Shell CEO Says No Arctic Drilling in 2014

On Jan. 30, Shell Oil announced that it has postponed plans to drill for oil in the Chukchi Sea off the northwest coast of Alaska in 2014. Shell’s decision followed a recent court decision that threw into question the status of Shell’s offshore oil leases in the Chukchi Sea—but other factors are at play, too.

As explained in my previous blog post, a panel of the 9th U.S. Circuit Court of Appeals recently ruled that an environmental analysis associated with the 2008 Chukchi Sea lease sale was faulty. Under the court’s decision, the Bureau of Ocean Energy Management will have to revisit that environmental analysis, and then decide whether to affirm its 2008 decision to sell the offshore leases. In the wake of the court ruling, Shell’s new CEO announced that the company is “not prepared to commit further resources for drilling in Alaska in 2014.”
