Oceans rising acidification eating away at shellfish that coastal tribes depend on

Indian Country: The ancestral connections of tribal coastal communities to the oceans natural resources stretch back thousands of years. But growing acidification is changing oceanic conditions, putting the cultural and economic reliance of coastal tribes--a critical definition of who they are--at risk. Its a big challenge to tribes in the Pacific Northwest, said Billy Frank Jr. (Suquamish) back in 2010, addressing the 20 tribes that make up the Northwest Indian Fisheries Commission. Its scary, he said...
Should We Be Exploring The Oceans Instead Of Space?

io9: For some, the irony is almost too much to bear. While Congress is eager to fund a $2 billion expedition to search for oceans beneath Europa, some 95% of Earth's oceans are unexplored. Given the role of oceans in regulating climate, and their untapped potential for food and health, is it time to rethink our priorities? This debate has been going on for half a century. Even John Steinbeck wrote an impassioned plea in 1966 to create a NASA for the oceans: While the lifeless rubbled surface of...

Climate Change May Shrink The Ocean's Dead Zones
2014-08-09 00:04:00| Climate Ark Climate Change & Global Warming Newsfeed
Nature World: Some good may come from climate change after all. Dead zones, the most oxygen deprive portions of our world's oceans, may actually be due for some shrinkage due to changing atmospheric patterns and water temperatures, according to a recently study. The study, published in the journal Science, details how the oceans low-oxygen swaths of water are likely to shrink as climate change continues to weaken trade winds. "The tropics should actually get better oxygenated as the climate warms up," Curtis...

Mercury Pollution in Oceans Has Tripled Since Industrial Revolution, Study Says

Yale Environment 360: Globally, oceans contain roughly 60,000 to 80,000 tons of mercury pollution, according to a report published this week in Nature detailing the first direct calculation of mercury pollution in the world's oceans. Ocean waters shallower than about 300 feet (100 meters) have tripled in mercury concentration since the Industrial Revolution, the study found, and mercury in the oceans as a whole has increased roughly 10 percent over pre-industrial times. North Atlantic waters showed the most obvious signs...

The search for survivors: Which species will outlast the rising acidity of oceans?
2014-08-07 16:00:00| Climate Ark Climate Change & Global Warming Newsfeed
ClimateWire: Many of the projected effects of climate change on the world's oceans are already visible, such as melting polar ice caps and rising sea levels. But invisible changes may be the most threatening to human food sources, beginning with the tiny species like plankton that inhabit the bottom of the oceans' food chain. As emissions from human activities increase atmospheric carbon dioxide, they, in turn, are modifying the chemical structure of global waters, making them more acidic. Many researchers...
