AB Pelagia noctiluca is the most common jellyfish in the Western Mediterranean Sea, living inoceanic waters with a holoplanktonic lifecycle. Frequent outbreaks have been well documented in coastal areas, yet little is known about their offshore distribution. In this study weaddress the relationship between oceanographic structures and the distribution of P. noctiluca ephyrae along the central continental slope of the Western Mediterranean, covering awide latitudinal gradient, during July-August 2016. The region is characterized by a rich andcomplex mesoscale surface circulation driven by the inflow of Atlantic Water into the Western Mediterranean through the Strait of Gibraltar. The results revealed a high variability inthe ephyrae spatial paterns related with different water masses and the resulting mesoscalehydrographic features. Their horizontal distribution showed a clear latitudinal gradient withhigh abundances in the south, associated with recent Atlantic Water, and low abundancesor absence in the north, in coincidence with the old Atlantic Water transported by the Northern Current. Ephyrae showed diel vertical migrations of short-extent in the first 50 m, with awide distribution above the thermocline and the Deep Chlorophyll Maximum during daytime,being more concentrated towards the surface at night. The results suggest the populationconnectivity of P. noctiluca between the Atlantic and the Mediterranean. In that case, theabundance variability of the species in the Mediterranean could be modulated by itsentrance associated with the inflow of Atlantic Water through the Strait of Gibraltar.
