A new NASA-led study using data from the Arctic Boreal Vulnerability Experiment (ABOVE) shows that carbon in Alaska’s North Slope tundra ecosystems spends about 13 percent less time locked in frozen soil than it did 40 years ago… The team combined data from more than 40 years of carbon dioxide surface measurements from NOAA’s Barrow, Alaska Observatory with a standard ecosystem carbon balance model to determine the rate at which carbon is moving in and out of Alaska’s North Slope.
