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.

Youngsters Need Energy to Grow

Posted On February 26, 2014 by

There’s a shift happening in the way scientists are thinking about how ocean acidification affects marine creatures. Originally, when researchers in the Southern Ocean watched the shells of tiny marine snails dissolve in high-carbon dioxide water, they suspected that similar animals with calcium carbonate shells and skeletons would most likely be harmed by ocean acidification. After all, this made intuitive sense: Ocean acidification means there is more carbon dioxide in the water, which lowers the water’s pH. All of this decreases the amount  of carbonate ions in the ocean—the chemical building blocks found in animals’ shells. Wouldn’t decreases in these building blocks rob animals of the very things they need to build their shells?

Ocean acidification biological research has looked at this “building blocks” hypothesis for a while. Many excellent studies have shown that time after time, decreases in seawater carbonate ion levels are associated with decreases in shell building by corals, plankton, oysters, and more. But that clear relationship doesn’t hold for crabs and lobsters, even though they too have calcium carbonate in their shells. And different shell formers respond to different degrees of change. What’s going on?

A Thousand-Yard-Long Buffet Table

Reading through the program for the 2014 Ocean Sciences Meeting, starting today in Honolulu, I’m like a hungry person at a buffet. But this isn’t just any buffet. Imagine the longest buffet table you’ve ever seen, loaded with all the dishes you love plus hundreds of interesting-looking new ones. Like that buffet table, this meeting program is packed with presentations about aspects of marine science I’ve always wanted to learn more about, and many that I’ve never thought of.

On my first read-through, I marked everything that looked interesting. And that wound up being about 300 talks, posters and plenary sessions over five days! I made the classic buffet eater’s mistake: My eyes are bigger than my stomach, or in this case, my brain. My selections range widely: Not only did I highlight every ocean acidification item, but I also highlighted things related to long-standing interests, like the nitrogen cycle and marine viruses. (Did you know there are viruses in the ocean? They attack the bacteria and other small creatures at the bottom of the ocean food web, and they’re really important in global carbon and nitrogen cycles!)

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.
