There is a less obvious source of carbon emissions than cars and factories: rivers and streams. Inland waters release carbon in the atmosphere, but their contributions depend on their concentration of dissolved inorganic carbon (DIC) from minerals and other sources. But what factors impact DIC concentrations? A team of Penn State engineers has now determined that both water discharge—or the volume of water flowing through a river or stream—and climate itself may have significant influence.
