Groundwater in the Arctic is delivering more carbon into the ocean than was previously known
A relatively small amount of #groundwater trickling through #Alaska's #tundra is releasing huge quantities of #carbon into the #ocean, where it can contribute to #ClimateChange, according to new research out of The University of Texas at Austin.
As the tundra continues to thaw and the flow of submarine groundwater ratchets up, Demir said that the outflow of carbon from shore to sea could effectively make ocean surface waters a carbon source to the #atmosphere. The #CO2 released via groundwater could also contribute to ocean #acidification.
"The #Arctic coast is changing in front of our eyes," said Bayani Cardenas, a co-author of this study and professor at the Jackson School's Department of Earth and Planetary Sciences. "As #permafrost thaws, it turns into coastal and submarine #aquifers. Even without this thawing, our studies are among the first to directly show the existence of such aquifers."
