When water levels in rivers rise, an area known as the "river’s liver" kicks into action, cleansing river water of pollutants and altering the flow of greenhouse gases into the atmosphere.
Now, in a paper published April 7 in Nature Communications, scientists at the Department of Energy’s Pacific Northwest National Laboratory present evidence suggesting that rising river waters deliver a feast of carbon to hungry microbes where water meets land, triggering increased activity, which could naturally boost emissions of carbon dioxide, methane and other greenhouse gases.
