- WG11. Laboratory of Marine Seismic Reflection and Bathymetry
- LA11. Marine Geology
Coordination: Pedro Terrinha, IPMA
Co-coordination: Carlos Ribeiro, UÉ
Institutions: IPMA, UÉ
Team 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.
+ DATA & PRODUCTS
- Maps and grids of geophysical data
- Offshore geological maps
Sismostratigraphy, chronostratigraphy, lithology and morphotectonics
- Thematic geologic maps of the seafloor
Geomorphology, habitats, paleo-coast lines and landslides susceptibility
- MINEPLAT WebSIG (beta version)
Continental Platform of the Alentejo Margin, Portugal – includes the high resolution visualization of the seabed (multibeam probe), the visualization of the substrate structure through ultra high resolution multichannel seismic profiles and the estimation of the location and size of geological bodies with high magnetic susceptibility.
