Effects of storms on primary productivity and air-sea CO 2 exchange in the subarctic western North Pacific: a modeling study
Biogeochemical responses of the open ocean to storms and their feedback to climate are still poorly understood. Using a marine ecosystem model, we examined biogeochemical responses to the storms in the subarctic western North Pacific. The storms in summer through early autumn enhance net community p...
