  abstract = {{T}he region located in the far northeast of the {G}ulf of {G}uinea ({NEGG}), eastern tropical {A}tlantic, remains poorly documented due to a lack of available in situ ocean data. {H}eavy rainfall and intense river discharges observed in this region induce a strong salinity stratification that may have a significant impact on the mixed layer depth and on sea surface temperatures, through the so-called barrier-layer effect. {B}y using recent in situ data and climatological outputs from a numerical simulation, we reveal the existence of a barrier layer in the {NEGG} and describe its seasonal occurrence. {I}n the {NEGG}, the barrier layer limits the mixed layer depth. {F}rom {J}anuary to {M}arch, significant values for the barrier-layer thickness are observed mostly due to the horizontal advection of fresh water. {F}rom {A}pril, vertical mixing along with vertical advection increase the sea surface salinity; hence, the barrier-layer thickness decreases and reaches its minimum in {J}uly. {D}uring the rest of the year, values for the barrier-layer thickness are again high, mostly under the influence of the {N}iger {R}iver discharge and precipitation, with the highest values recorded in {O}ctober, when the river discharge and precipitation are at a maximum.},
