Researchers conducted a survey of more than 2,500 U.S. Gulf Coast residents to learn how their lives have been affected since Deepwater Horizon. Survey results show that most people who had social support were less likely to screen positive for depressive symptoms in the years following the oil spill.

Researchers analyzed the metabolic capability of three Gulf of Mexico fish species after being exposed to toxic polycyclic aromatic hydrocarbon (PAH) compounds. Florida pompano exhibited faster biotransformation rates for hydroxylated naphthalene and phenanthrene compounds than red drum and southern flounder.

March 12 Sea Grant Seminar on Herding Oil At the Ocean's Surface
The Sea Grant Oil Spill Outreach Team will host a seminar in Metairie, Louisiana that covers the history, science, and logistics of using collecting agents for an oil slick. This seminar will coincide with a Coast Guard Area Committee meeting. Speakers include Tim Nedwed (ExxonMobil Upstream Research Company), James Hanzalik (Clean Gulf Associates), David Cooper (SL Ross Environment Research Limited), Srijan Aggarwal (University of Alaska Fairbanks), and George John (The City College of New York). More information available here.
Sea Grant Releases Educational Videos on Seafood Safety and Fish Coping with Oil
The Sea Grant Oil Spill Outreach Team in collaboration with O’Chang Studios developed animated videos appropriate for public and classrooms use: “How fish cope with exposure to oil” and “Ensuring the safety of seafood after the Deepwater Horizon oil spill.” Viewers can learn about seafood safety testing methods used after the oil spill and can learn how fish's bodies process oil after exposure. Videos are available here.

CARMMHA Blog Highlights Novel Method for Aging Wild Dolphins
Previous methods for measuring a dolphin’s age typically involved removing its tooth and counting growth layers within the tooth, similar to tree rings. The consortium collaborated with researchers at L'Oceanogràfic, a Spanish oceanarium, to design an effective, less-invasive aging method using X-rays of the animal’s pectoral flippers. Read the post to learn how this new method can help researchers assess the health of free-range dolphin populations.
