Microphytobenthos biomass (chlorophyll) and production (oxygen budget) were studied in the Great Astrolabe Reef lagoon in April and May 1993. In this study, the term microphytobenthos includes cyanobacteria and all the unicellular algae living in or on sediments. Biomass estimated with chlorophyll was present until 8 cm depth in the sediments. In average, chlorophyll concentration at the SWI was 8.3 plus or minus 1.2 mg Chl/m2 (upper 0.5 cm). Net production appeared negative or positive independently of the station depth. Average gross production was 0.3 g C/m2/day and strongly correlated with the station depth. Biomass and production were in the range of French Polynesian lagoon data. (Résumé d'auteur)
