A 14C method for measuring epibenthic microalgal productivity in air

A modified 14CO 2 technique is described for measuring epibenthic microalgal productivity in intact sediment cores under low tide conditions (exposed to air). The procedure allows for a great deal of experimental versatility with experimental manipulation of light intensity, temperature, atmospheric...

Summary:A modified 14CO 2 technique is described for measuring epibenthic microalgal productivity in intact sediment cores under low tide conditions (exposed to air). The procedure allows for a great deal of experimental versatility with experimental manipulation of light intensity, temperature, atmospheric composition, mineral nutrients, and salinity. The method may be modified to measure the excretion of dissolved organic matter by the algae on their natural substratum.
