Protection sought for 66 coral species, study shows humans are their largest threat. NOAA Fisheries has proposed listing 59 Pacific and 7 Caribbean coral species on the Endangered Species Act. An analysis shows that human population growth and resource consumption underlies the greatest threats to corals. [The New York Times; The Los Angeles Times]


Arctic ice melt continues to set records; Antarctic glaciers, are melting faster than expected.  A report indicated that snow and ice melt records were broken throughout 2012 in the Arctic, despite unremarkable air temperatures, while another study indicated that increased melting of the West Antarctica ice sheet stems from warm seawater.  [Science Daily]


Mercury contamination in seafood greater risk than previously thought. Mercury contamination is on the rise, and health consequences are greater than previously believed even at lower levels, suggesting that updating consumption guidelines may be necessary. [The Huffington Post]


Protection from drilling sought for Sonoma, California coast. Legislators are aiming to create California’s largest ocean preserve in 20 years by protecting 50 miles of the Sonoma and Mendocino coastlines, essentially adding 2,771 square miles to the existing Gulf of the Farallones and Cordell Bank National Marine Sanctuaries and banning offshore oil drilling in that area.

Abalone raised in classrooms will be released to restore wild populations. Marine biologist Nancy Caruso has been working with Orange County middle and high school classes, to raise green abalones, a National Marine Fisheries Service Species of concern, in classrooms. Several abalone species are endangered. [OC Register]


Data released from James Cameron’s trip to Ocean’s Deepest Point. The Mariana Trench was described as a relative desert, compared to other deep dive sites visited in preparation for the trip, which yielded observations of communities of acorn worms and sea anemones, as well as microbes living in conditions that may have implications for the origins of life on earth and other planets.
