WE STUDY THE GEOLOGY AND GEOPHYSICS OF CONTINENTAL MARGINS AND BASINS

A continental margin is a submerged region on the edge of a continent that joins the ocean floor, where the transition from the continental to oceanic crust t takes place.

How

We work with multidisciplinary and multiscale approaches, using a great variety of tools

Where

From challenges to research

1. Global change, sedimentary systems and models

The study of the sedimentary record of continental margins and ocean basins allow us to reveal the palaeogeograpic, palaeoclimatic, palaeoceanographic and the geological history at different time-scales.

Singular and convulsive geological process

Major oceanographic and sedimentary convulsive event in the Mediterranean: the impact of the Atlantic flooding after the opening of the Strait of Gibraltar that put an end to the Messenian Salinity Crisis.

Evolution and interaction of sedimentary systems

Models of interplay between the alongslope and downslope sediment transport and their control on the Plio-Quaternary submarine fans architecture. From Ercilla et al., 2019.

2. Marine Geological Hazards

We map and define all phenomena or condition that represent a geological hazard coming from the sea. We pay special attention to faults and mass-transport processes and their tsunamigenic potential.

Mass-transport processes

The slope stability and mass transport processes is one of the main target in marine geohazard..

3. Conservation fo oceans

Marine Litter

We also focus on the characterization of the marine litter on the seafloor and the potential factor controlling their distribution.
