Géosciences marines


The Marine Geosciences Team at IPGP has a staff of ~ 40 people, including permanent scientists, students and postdocs, and administrative and technical staff.  Our ofus is the study of the seafloor and the oceanic crust, and the processes that shape it and operate within it, from the mid-ocean ridge system to the subduction zones where it is recycled into the mantle. We thus focus our research both in fundamental scientific problems (origin and evolution of the crust, nature of volcanism and faulting), and applied research (exploration geophysics related to resources). To achieve this we have a multidisciplinary approach, including geology, petrology, geochemistry, and geophysics.


Our main scientific activity is based on oceanographic cruises to explore areas of interest world wide.  We also maintain and develop instrumentation for deep-sea geological and geophysical studies, including marine ocean bottom seismometers (Parc OBS), autonomous temperature sensors, chemical sensors, and curremetmeters for hydrothermal studies. Our Group is also involved in the management and maintenance of the EMSO-Azores deep-sea seafloor observatory. Information our our upcoming seminar  (open to all and taking place at IPGP) is available here (and past ones as well as IPGP's other seminars here).

Since September 2019, our team, jointly with the Tectonics lab at IPGP, benefits of 10 MOVE software licenses, which have graciously been donated by Petroleum Experts Ltd (PETEX), for the equivalent of £1,409,059.98.  This will allow us to strengthen skills in 3D structural geology study, and:

-- to reconstruct the eroded region in a cross-section of accretionary prism based on the geometry of lower stratigraphic horizons;
-- to quantify the amount of strain, shortening and uplift of a range of sedimentary layers using bed-length measurement and area balancing;
-- to progressive restore the history of thrust wedge to understand the major deformation stage and their relationship with regional tectonic processes;
-- to identify the regions of active faults with largest on-going deformation and potential highest seismic hazards.

















For active-source seismic and OBS data processing our team is using Echos software, kindly provided by Emerson E & P company as part of a long-term partnership.
