The relationship of solar-stimulated natural fluorescence and primary productivity in Mexican Pacific waters. Limnology and Oceanography 41
Solar-stimulated natural chlorophyll a fluorescence measured by upwelling radiance in the red spectral band could be a fast and noninvasivc method to estimate primary production in aquatic environments if the relationship of primary production to natural fluorescence can be described as a function o...
