  abstract = {{I}n situ sea surface salinity ({SSS}) observations showed an increase >0.5 over the period 2002-2009 in the {G}ulf of {G}uinea, off the {N}iger {D}elta. {O}bserved changes in the {N}iger {R}iver runoff were not consistent with this increase in {SSS}, but the increase was reproduced in a regional numerical simulation with climatological river runoff. {T}he simulated mixed-layer salinity budget was used to identify the mechanisms responsible for the increase. {W}hen comparing the period 2002-2009 with the period 1993-2001, significant changes in the salt budget were identified. {T}he increase in {SSS} in the more recent period appeared to be driven by changes in the atmospheric freshwater flux, mainly attributed to a regional decrease in precipitation. {H}orizontal advection partly compensated for the effect of freshwater flux through changes in zonal currents and zonal {SSS} gradients.},
