Abstract
We capture water column ventilation resulting from coastal upwelling in continuous records of O2/N2, CO2, and N2O at Trinidad, California. Our records reveal the gas exchange response time of the ocean to the upwelling and ensuing biological production. Satellite and buoy wind data allow extrapolation of our records to assess coastal upwelling air‐sea fluxes of O2 and N2O. We improve on previous regional estimates of N2O flux in coastal and continental shelf region of the western U.S. We characterize the source of N2O as being predominately from nitrification based on the O2/N2O emissions ratio observed in our atmospheric records.This publication has 23 references indexed in Scilit:
