Antarctica's Deep Lake is a saltwater ecosystem that remains liquid in extreme cold. For the first time, researchers describe a complete ecological picture of the microbial community thriving in Deep Lake.
Every bluefin tuna tested in the waters off California has shown to be contaminated with radiation that originated in Fukushima. Every single one. Over a year ago, in May of 2012, the Wall Street Journal reported on a Stanford University study.

TOKYO -- Japan’s crippled Fukushima nuclear plant has suffered yet another leak, spilling out 430 liters of contaminated water thousands of times more radioactive than legal limits, its operator said Thursday.
A little over one month after traversing the Northeast Passage (Russia), Tara crossed the Canadian Northwest Passage on Saturday, September 28th. The Tara Oceans Polar Circle expedition continues its goal to better understand the Arctic ecosystem by exploring the rarely studied planktonic species near the pole.
On Saturday, an extremely stable anti-cyclone presided over the northern Canadian Nunavut region, allowing Tara to sail in perfect weather conditions. At dawn, Tara entered the Prince Regent Inlet, scattered with new ice typical at this time of year as the ice pack begins to reform.
In the morning, Tara’s captain, Loïc Vallette received a radio message from the Canadian Coast Guard icebreaker Louis S. St-Laurent inviting Tara to be escorted. This enabled Tara to cross a barrier of 100 km in half a day, through ice 15 cm thick covering 95% of the surface. Without help from the Canadians, the schooner would have taken a lot more time, including a crucial slalom in the dark between new and old ice floes.

Scientist and explorer Sylvia Earle warns that the oceans are "not too big to fail." But she also says that just maybe, we're growing wise enough to save them.
Sylvia Earle hasn't quite spent a year under water—yet. At age 78, she's at over 7,000 hours, which translates into about 292 days.
But she's going strong. "I just added a few more hours to time under water," Earle says, "because I've just returned from the Gulf of Mexico, 100 miles offshore to a place called theFlower Garden Banks, where at this time of the year, several key species of corals whoop it up and do what it takes to make more corals." Earle is referring to the phenomenon of mass coral spawning, in which huge numbers of corals all release gametes into the water at once, which in turn float to the surface where fertilization occurs. To hear divers tell it, these events of mass reproduction are one of the great wonders of the undersea world—one that all too few of us ever get to see.

World's oceans facing climate change triple threat Scotsman Environmentalists fighting to preserve Scotland's seas say the findings highlight the need for the Scottish Government to establish a network of designated Marine Protected Areas.
The health of the world’s oceans is deteriorating even faster than scientists previously thought, a report says.
Marian Locksley's insight:
The co-coordinator, Prof Alex Rogers from Oxford University has been asked to advise the UN's own oceans assessment but he told BBC News he had led the IPSO initiative because: "It’s important to have something which is completely independent in any way from state influence and to say things which experts in the field felt was really needed to be said."
He said concern had grown over the past year thanks to papers signalling that past extinctions had involved warming seas, acidification and low oxygen levels. All are on the rise today.
Over the years, as fisheries in shallow waters collapsed, the fishing industry began looking to the deep for new species to exploit. Most deep-sea fish have flesh that is not palatable, but a few were found that could be marketed for human consumption, if filleted and renamed to be made more attractive, or for processing into food pellets for poultry. These stocks were readily attacked using trawls large and heavy enough to reach as deep as 2,000 meters, and it took only 10 to 15 years to reduce the fish biomass by about 80 percent.
"The scale and rate of the present day carbon perturbation, and resulting ocean acidification, is unprecedented in Earth's known history," according to the report, made with the International Union for Conservation of Nature.
