Project activities

  • Activity 1: Equipment for initiating seafloor geodesy in France and creating a national community ofresearchers in marine geodesy, through shared national facilities, resulting in reduced PI-driven project costs. It will promote exchange and sharing of know-how, methodological research and the implementation of community experiments for the acquisition of collective expertise.
  • Activity 2: Equipment for rapid response and monitoring of seismic and volcanic crises, using geodetic/seismo logical light-weight sensors, readily transportable, to be deployed within a few days from small opportunity ships, to capture the process when signals are expected to be the largest. This equipment will provide high-resolution data to the scientific community and to the civil protection authorities for improved crisis response and management.
  • Activity 3: State-of-the-art ocean-bottom seismometers pool for seismic imaging and for solid earth and marine environment research.
  • Activity 4: Research and development on optic fiber applications at sea for: i) improving data processing for Distributed Acoustic Sensing systems; ii) implementing innovative geophysical sensors using Fabry-Perot interferometry; and iii) developing innovative high-sensitive strainmeter sensors within single optical fiber.
  • Activity 5: Mayotte multidisciplinary seafloor and water column observatory, including:  i) an electro-optical and optical fiber cable network for continuous real-time 24/7 high-resolution secured data acquisition from 3 fixed multiparameter stations and data transmission on land; ii) autonomous multi-parameter stations equipped with sensors for geophysics, geochemistry, biology and ecology.
  • Activity 6: Information System: The IS will guarantee open and compliant data access from all the instruments acquired.
