Abstract

A method is described for determining the quantum efficiency (carbon fixed–quanta absorbed) of in-situ oceanic photosynthesis. The method makes use of a photoelectric sensor, called a chlorophyll-simulator, that gives a reading directly proportional to the absorption of quanta by the chlorophyll-a in the phytoplankton. The method is not sensitive to changes in the amount or spectral distribution of the natural incident light.
