FPI Predoctoral Scholarship (2013). Thesis adviser: A.García-Olivares

With a grant inside the TIC-MOC (Ref.CTM2011-28867) project, which aims to study the hydrodynamics from three Atlantic regions of great interest for their role in regulating the intensity of the Meridional Overturning Circulation (MOC).

The thesis focuses on the study of two of them: The output of the Mediterranean Water (MOW) through the Strait of Gibraltar, and the South Atlantic where, besides forming deep water, most of this water upwelling occurs and its transportation to the Northern Hemisphere.
My PhD has two different parts:
In a first analytical simulation output Mediterranean Water (MOW) through the Strait of Gibraltar to see the influence on the regulation of the Global Conveyor Belt (MOC), both at the present time and in the last glacial period. The model used is ROMS (Regional Ocean Modeling System) that uses the primitive equations, using a free surface sea level, and a terrain-following or sigma coordinates.

On the other hand I start the analysis and characterization of the Brazil-Malvinas Confluence Zone in the South Atlantic are performed using hydrographic data already in the XV FICARAM campaign and the campaign of the ICT-MOC project developed in this region between 5 / 3/2015 to 03/30/2015. By analyzing recent data the different water masses will be characterized and the transport will be calculated for each of them.
