Ocean Acidification Wrecks Sharks’ Smellovision

Posted On August 20, 2014 by

Scarier than any movie shark that can smell a drop of blood miles away (they can’t, by the way) is this week’s news about sharks’ sense of smell. A team of Australian and American scientists has just shown that smooth dogfishes (also called dusky smooth-hound sharks) can’t smell food as well after living in ocean acidification conditions expected for the year 2100. These “future” sharks could correctly track food smells only 15% of the time, compared to a 60% accuracy rate for unexposed sharks.  In fact, the acidification-exposed sharks even avoided food smells!

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.

800,000 and Counting: The Soaring Deepwater Horizon Bird Death Count

Posted On May 22, 2014 by


According to a new study, scientists estimate that between 600,000 and 800,000 coastal seabirds died because of the BP Deepwater Horizon oil disaster, a number far greater than any previous estimate. Understanding the ripple effect of 800,000 coastal birds dying in the Gulf of Mexico is critical to the recovery of this special place. These findings come from a study to be released this summer in Marine Ecology Progress Series, which was recently reported in the New York Times.

This new estimate for bird deaths in the Gulf is unprecedented for an oil disaster. For context, the estimate of dead birds following the Exxon Valdez Oil Spill was around 300,000.

What are the ecosystem effects of 800,000 birds dying?

Connecting the Head and the Heart: Taking Action on Ocean Acidification

Posted On May 1, 2014 by

Even though ocean acidification is a pretty young issue, scientists and journalists already have developed two distinct storylines about it. Scientists start with the details and describe the impacts of ocean acidification last. Journalists put the impacts up front and fill in the details where they fit in. But to create long-lasting action around ocean acidification, we need to connect the two approaches in a new way. Here at Ocean Conservancy, we’re working on exactly that.

Oil and Ice Still Don’t Mix in the Arctic

Posted On April 30, 2014 by

On April 23, the National Research Council (NRC) released a new report that reviews state of science and technology with respect to spill response and environmental assessment in the U.S. Arctic Ocean. Ocean Conservancy provided recommendations and comments to the NRC as it conducted its research last year.

Now that the NRC has published its final report, we are pleased to see that it confirms what we’ve known all along: there are major barriers to effective oil spill response in Arctic waters. These include lack of information, lack of infrastructure, and lack of preparedness to deal with adverse environmental conditions.

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.

Presenting Our New Solutions at the Camden Conference

Posted On March 20, 2014 by

Last month, I was invited to speak at the Camden Conference in Maine. This conference brings experts from a number of disciplines together with policymakers, industry leaders and college students to discuss some of the biggest issues facing our world today. This year’s theme was “The Global Politics of Food and Water,” and I spoke about how the ocean sits at the nexus of these issues.

Right now, the ocean is in a period of uncertainty. Climate change and a growing population are changing the chemistry of the ocean and the life that calls it home. But instead of viewing the ocean’s changes in a negative light, I think we have an incredible opportunity to become better problem-solvers. We can break free from old resource management models to find new solutions for our changing ocean. We can effectively address these new complexities; it’s not too late.
