Arctic lakes are emitting young carbon

Arctic lakes For now, the most ancient carbon remains locked up and frozen deep in the Arctic tundra. The latest investigation of the Arctic's carbon cycle suggests Arctic lakes are emitting relatively young carbon.

Scientists at the University of California, Irvine used carbon-14 dating methods to identify the age of carbon molecules escaping lakes in northern Alaska. Researchers sampled a diverse array of lakes -- during both summer and winter -- spread across Alaska's North Slope.

Their analysis -- detailed this week in the journal Nature Climate Change -- suggests the carbon being released was only recently deposited.

"These young carbon pools most likely include comparatively fresh photosynthetic products flushed into the lakes from their surrounding watersheds, organic material from aquatic plants and phytoplankton, or waterborne dissolved inorganic carbon," lead study author Clayton Elder, now a research scientist at NASA's Jet Propulsion Laboratory, said in a news release.
