Abstract
    Primary production parameters (numbers and identifications , pigments, photosynthesis, respiration, excretion) have been measured or estimated in a marine lagoon during 4 years. On the seasonal scale, the succession pattern shows a spring bloom in April-May, a depression in May and a summer bloom from June to August. Various nannoplanktonic flagellates are responsible for these fluctuations, which are well paralleled by photosynthetic capacity variations. Primary production was computed using a light-photosynthesis function. Photosynthetic capacities and function parameters have been determined and discussed. On the diel scale, a strong periodicity involving natural mortality was observed and taken into account. Uptake and regeneration rates of inorganic N as well as liberation and consumption of dissolved O2 matched this periodicity well. Turn-over times are very short and according recycling is intense.
