  abstract = {{T}he surface fugacity of {CO}2 (f{CO}(2)) has been measured hourly at a mooring at 8 degrees {N}, 38 degrees {W}, using a spectrophotometric {CO}2 sensor, from {J}une to {O}ctober 2013. {I}n {S}eptember 2013, the f{CO}(2) and the sea surface salinity ({SSS}) decrease significantly. {T}he high precipitation due to the presence of the {I}ntertropical {C}onvergence {Z}one ({ITCZ}) and the propagation of low salinity waters from the {A}mazon {R}iver plume explain the decrease of {SSS}. {I}ndeed, in fall, the retroflection of the {N}orth {B}razil {C}urrent ({NBC}) feeds the {N}orth {E}quatorial {C}ounter {C}urrent ({NECC}) and transports {A}mazon waters to the eastern part of the tropical {A}tlantic. {S}imulations from a three dimensional physical and biogeochemical model and observations at the mooring show that the {A}mazon plume reached the mooring in {S}eptember 2013. {T}he decrease of f{CO}(2) is associated with a moderate peak of chlorophyll. {O}ver the period of the {CO}2 observations, the site is a source of {CO}2 to the atmosphere of 0.65 +/- 0.47 mmol m(-2) day(-1). {A}lthough the wind speed is at its lowest intensity in {S}eptember 2013, the flux over the whole period would be about 14% higher without this month. {E}very month of {S}eptember from 2006 to 2017, the model simulates a decrease of dissolved inorganic carbon corresponding to the {SSS} minimum.},
