  abstract = {{A} mooring at 6 degrees {S}, 10 degrees {W} has been equipped with an oxygen optode and a {C}arioca sensor for monitoring hourly oxygen ({O}-2) and the fugacity of {CO}2 (f{CO}(2)) at 1.5 m depth since {J}une 2006. {D}ue to biofouling, the oxygen time series lasted between 72 days in 2008 to 159 days in 2009. {U}sing an alkalinity-salinity relationship determined for the area, dissolved inorganic carbon ({DIC}) is calculated. {S}hort-term and long-term net community productions ({NCP}) are calculated using a mass balance approach for {DIC} and {O}-2 under the assumption of no mixing conditions. {T}he mooring site is always supersaturated in oxygen except in 2007 when depleted oxygen waters are observed from {J}une to {S}eptember, during the upwelling season. {A}veraging all the short time events, {NCP} calculated from the rates of changes of {O}-2 and {DIC} leads to a {NCP} of 16.6 +/- 6.1 mmol {C} m(-2)d(-1), ranging from 14.7 mmol {C} m(-2)d(-1) in 2008 to 17.4 mmol {C} m(-2)d(-1) in 2006. {T}he mean daily oxygen biological production rate determined over the whole time series shows a significant year to year variability with 7.5 mmol {C} m(-2)d(-1) in 2008 to 15.6 mmol {C} m(-2)d(-1) in 2009. {A} photosynthetic quotient ranging between 1.0 to 1.3 has been determined when both carbon and oxygen {NCP} values are available.},
