Short summary
We characterized the water masses of the Senegalese Petite Côte and described spatial and temporal variations of SSLs in relation to their environment. SSL distributions were mainly structured by bottom depth, diel period, and the level of vertical stratification in the water column. This study serves as a precursor in the field of SSL study in the Senegalese Petite Côte and even West African coasts, hence the importance of this work.
