  abstract = {{T}o assess the eastern {A}tlantic tropical mixed layer depth ({MLD}) at 4 degrees {W} in the {G}ulf of {G}uinea, water temperature and density profiles from over five hundred historical observational {C}onductivity - {T}emperature - {D}epth ({CTD}) data were used. {T}hese data, obtained from key oceanographic survey databases covering 60 years (1956 to 2016) were used for a numerical and visual determination of the {MLD}. {T}he numerical approach consists of the use of the algorithms of three methods; while the visual estimation of the {MLD} were made on both temperature and density profiles. {T}he numerical approaches were evaluated by comparing their results on the determination of tropical {MLD} with those of the visual inspections by means of statistical and graphical analysis in order to determine the most suitable method for the determination of {MLD} in the study area. {O}ur results show that the {B}oyer {M}ontegut density threshold method (potential density) with the constant criterion {D}elta sigma = 0.03 kg.m(-3) and a reference depth of ten meters is the most appropriate for determining the {MLD} in the {G}ulf of {G}uinea regardless the season. {H}owever, in the situation where only temperature profiles are available it is advisable to estimate {MLD} using the {L}orbacher curvative method.},
