Jetsam (what we’re reading from around the web)

“I imagine pollution in the Mariana Trench is an abstract concept for most people, but for those of us living in the Mariana Islands this has consequences for what ends up on our dinner plates,” says Angelo Villagomez, an indigenous Chamorro from the Mariana Islands who works for the Pew Bertarelli Ocean Legacy Project. “So what can we do? The International Union for the Conservation of Nature recommends we protect 30 percent of every marine habitat to address human impacts, but that will only help if we’re also sustainably managing the remaining 70 percent, reducing carbon emissions, and limiting the pollution being dumped in the ocean in the first place.”

Scanning electron microscope examinations of pteropod shells show how the calcium carbonate dissolves in acidified water. In the first image, a healthy shell is smooth and full, while in the second, a closer zoom on a shell that had been exposed to acidified water shows it to be rough and pockmarked.
