From: Light-dependent grazing can drive formation and deepening of deep chlorophyll maxima
Global comparison of deep chlorophyll maxima (DCM) depths predicted by COBALT and satellite algorithms. a, b Carbon, Ocean Biogeochemistry and Lower Trophics (COBALT) global marine biogeochemistry model output for the unmodified (control) model (a) and model modified to incorporate light-dependent grazing of microzooplankton (b). Note an overall deepening in the DCM, particularly in the oligotrophic gyres. c Empirical estimate of DCM depth using a pigment-based algorithm interpolated using satellite data. Modification of the COBALT model to incorporate light-dependent grazing improves the model’s match with these data. All panels are plotted using the same colorbar scale
