Scientists reveal regional coupled C-N-H2O cycle processes and associated driving mechanisms

From a molecular level to an ecosystem scale, different coupling mechanisms take place during coupled carbon-nitrogen-water (C-N-H2O) cycles, of which essential are water flux and related biogeochemical processes through physicochemical reactions associated with terrestrial and aquatic ecosystems that will subsequently impact regional gross primary productivity (GPP) and C and N exchanges during air-water interactions that occur downstream of watersheds.
