Happy Friday!

As we speak, an Oceana team is headed to the CITES conference in Doha, Qatar, which begins tomorrow. We will be bringing you updates from the conference as we push for trade restrictions for bluefin tuna, corals and sharks.

CITES wasn't the only thing on the ocean radar this week, though. Check out the rest of this week's stories:

…Scientists have found that oxygen-starved pockets of the ocean, known as dead zones, can contribute to climate change. The increased amount of nitrous oxide produced in low-oxygen waters can elevate concentrations in the atmosphere, exacerbating the impacts of global warming and contributing to holes in the ozone layer.

… OK, this one’s a little gross -- but also really cool. Forensic researchers recently dropped several dead pigs into an ocean dead zone off Vancouver Island to gain insight into how fast cadavers in an ocean can disappear thanks to scavengers. Marine researchers took advantage of the study to do their own by using an underwater camera to see what kinds of animals fed on the disintegrating dead pigs -- and how long they could tolerate low-oxygen zones. While crabs, shrimp and starfish normally stay at shallower depths (where there’s more oxygen), the scavengers pushed their limits for the pig pickin’. Who knew swine could be such a boon for ocean science?
