Latest Ocean chemistry Stories
Some 56 million years ago, a massive pulse of carbon dioxide into the atmosphere sent global temperatures soaring. In the oceans, carbonate sediments dissolved, some organisms went extinct and others evolved.
A NOAA-led research team has found the first evidence that acidity of continental shelf waters off the West Coast is dissolving the shells of tiny free-swimming marine snails, called pteropods, which provide food for pink salmon, mackerel and herring
Tiny crustaceans, known as copepods, live just beneath the surface of the ocean. A research expedition to the Arctic, part of the Caitlin Arctic Survey, found that these tiny animals are more likely to battle for survival if ocean acidity continues to rise.
Acidification of the Arctic Ocean is occurring faster than projected according to new findings published in the journal PLoS One.
In the journal Global Change Biology, a worldwide study is published to understand and forecast the likely impact of ocean acidification on shellfish and other marine life living in seas from the tropics to the north and south poles.
Changes in ocean chemistry due to increased carbon dioxide (CO2) emissions are expected to damage shellfish populations around the world, but some nations will feel the impacts much sooner and more intensely than others.
Projects address concern for acidifying marine ecosystems.
Emissions of carbon dioxide are causing ocean acidification as well as global warming.
The changing chemistry of the world's oceans is a growing global problem. Unless man-made carbon dioxide (CO2) emissions are substantially curbed, or atmospheric CO2 is controlled by some other means, the ocean will continue to become more acidic.
Scientists at Columbiaâ€™s Lamont-Doherty Earth Observatory have found evidence of hydrothermal vents on the seafloor near Antarctica, formerly a blank spot on the map for researchers wanting to learn more about seafloor formation and the bizarre life forms drawn to these extreme environments.
- Having no light.
- Of or relating to the region of a body of water that is not reached by sunlight and in which photosynthesis is unable to occur.
