| At the ocean surface, satellite observations have shown evidence of a large spectrum of waves at low latitudes. However, very little is known about the existence and properties of the deep variability. Most of the subsurface observations rely on localized measurements, which do not allow for a global estimation of this variability. In this study, we use velocity estimates, provided by Argo float drifts at 1,000 m, to analyze the spatial and temporal distribution of the deep eddy kinetic energy (EKE) and its spectral signature with an unprecedented time and space coverage. In the tropical Pacific, high EKE is found along the equator, at the western boundary and poleward of 7°N. EKE meridional distribution is also found to vary at the scale of the... |

| This article cantains the data gathered during the Escarmed campaigns carried out by the Comité d'Études Pétrolières Marines (CEPM) and the Centre National pour J'Exploitation des Océans (CNEXO) and situates theïr interpretation within the framework of what is known about the Apulian subsea platform or the Apulian plateau. It includes: (a) Two 1 :100,000th bathymetric maps giving details of the southern dm of the Apulian plateau and the Cephalonian scarp. (b) An analysis of the morphology of these scarps, mainly governed by the active tectonics and considerable erosion of the carbonate cliffs. (c) A review of seismic and stratigraphie data showing a subsidence of this damain during the entire la te Cretaceous. (d) A discussion of the history of these... |
