  abstract = {{B}enthic exchanges of oxygen and nutrient at the sediment-water interface were investigated under light and dark conditions at 5 selected sites in a sub-tropical atoll. {M}ean oxygen fluxes were - 1316.5 +/- 242.0 mu mol m(-2) h(-1) and mean effluxes of oxygen under light conditions were 2231.7 +/- 626.4 mu mol m(-2) h(-1), presumably due to microphytobenthos present at the sediment-water interface. {T}he consequences of this high related productivity was a systematic consumption of nutrients ({DIN}, {PO}4 and {S}i({OH})(4)) during almost all light incubations, contrasting with the effluxes of nutrients during dark incubations. {O}ur results suggest that the sediments were net autotmphic and the oxygen balance in favor of microbenthic production when compared to community demand. {D}iurnal rates of gross benthic primary productivity were high (3423 +/- 1192 mu mol m(-2) h(-1)) which emphasize the role of microphytobenthos in maintaining the oxygen reservoir in tropical lagoons.},
