We describe a novel experimental method to quantify simultaneous photochemical–microbial degradation, and show that interactive photochemical–microbial degradation can account for around half of tDOC and of colored dissolved organic matter degradation. The degradation rates depend asymptotically on the absorbed light dose rate. Our method yields a simple equation that relates the interactive tDOC degradation rate to the absorbed light dose rate, which can be adapted to represent tDOC degradation in biogeochemical ocean models.
