Abstract
The Tikehau atoll (Tuamotu Archipelago, French Polynesia) is located at 14'5 148W. Phytoplankton and sand microalgae are the most important primary producers of the lagoon. They were studied for 4 years. The relationship between light energy and lagoonal primary production was measured by using the 14C method for phytoplankton and O, method for phytobenthos. Incubations, carried out in situ, were made at different depths and light exposition times. Irradiance was high and 17% of the light energy measured at the surface reached 25 m (lagoon average depth). Maxima of phytoplankton and phytobenthos productions occurred at low depths; there was therefore no photoinhibition of photosynthesis. Correlations between light energy and primary production were strong, especially for phytobenthos. Multiplicative linear regression models (production VS light) associated with an exponential linear regression model (light vs depth), allowed planktonic and benthic primary production to be predicted from the depth and the light energy received at the surface. The benthic primary production exceeded the phytoplanktonic production in the upper 18 m. The total primary production (benthos + plankton) was constant with depth and depended only on light energy at the surface. One Einstein received at the lagoon surface allowed the growth production of 14 mg of carbon (water column + sediments).
