A research team at the NOAA NMFS Auke Bay Lab explored the physiological effects of acidification on marine fishes with an experiment to determine the effects of lowered pH on survival and growth of Pacific herring embryos.  MORE >>

Are the Earth's Oceans Hitting Their Carbon Cap? 11/19/09

The planet's oceans serve as a vital carbon sink however research shows that the oceans' ability to absorb man-made carbon may be dwindling  MORE >>

Arctic land and seas account for up to 25 percent of world’s carbon sink 10/14/09
11/02/2009 | Marilyn Sigman, Alaska SeaGrant/MAP
Tags: Climate Change, Changing Arctic Sea Ice, Arctic Ocean, Carbon Cycling,
According to a new study, ecologists estimate that Arctic lands and oceans are responsible for up to 25 percent of the global net sink of atmospheric carbon dioxide. Under current predictions of global warming, this Arctic sink could be diminished or reversed, potentially accelerating predicted rates of climate change.  MORE >>
