PhD  Topic: The Origins of Continental shelves: The Iberia study case. How the inheritance of the deep structure affects the superficial physiography of the continental shelves.

 Motivation: Continental shelves have been widely discussed from the ‘80s, they are extremely dynamic environments that extend from the coast to the abyssal plain in a relatively flat surface. They represent merely the 8% of the entire marine ecosystem but nonetheless, they are the areas on the where different processes interplay shaping its morphology through erosion, sedimentation or tectonic adjustments being challenging task understanding their main relation. Although this morphology evolution we think that the long-term physiography strictly depends on the shelf hereditary deep structure, which in the case of the Iberia, it Is very complex and varied (Inverted margin in the North, rifted margin on the Westside and Convergent margin in the South). Moreover, the geology on land represents often a point of discontinuity in the shelf physiography. For this reason, a better understanding of the beneath shelf structure/behave might give us a more confidence to include that among the most relevant factors that influence the other evolutionary patterns.
Objectives:

– Understanding the Environmental processes (geology, climate and oceanographic) that govern the geomorphology of the continental shelf in Iberia and North East European shelf
– The role of tectonic invest a primary role in the shelf formation
– The implication of the deep shelf structure in the control of the surface physiography
