• WG11. Laboratory of Marine Seismic Reflection and Bathymetry
  • LA11. Marine Geology

Coordinator: Pedro Terrinha, IPMA
Institutions: IPMA


Working group and line of action consisting of a Laboratory unit for the acquisition, processing and interpretation of marine geophysical data (2D and 3D seismics, magnetics and gravimetry) and their geological integration – from estuaries to abyssal bottoms.

Aims to provide services to C4G partners, the national and international scientific community, the public and the private entities; to offer advanced training; to construct integrated geological and environmental models (geophysical, geochemical) for the characterization of the seabed and subsoil and crustal structure; to map the marine habitat; to assess marine geological risks and resources and; to integrate the international community on deep sea substrate research.
