Research priorities

The project of the IUEM research units can be presented very schematically in four main themes, broken down into objects and processes that researchers wish to better understand.

The ocean, a major actor in the biogeochemical cycles and climate of our planet

  • Warming and ocean circulation in the past, present and future.
  • The chemical composition of the ocean (particularly trace metals) and major cycles: ocean acidification, deoxygenation, carbon cycle, pollution (e. g. heavy metals).
  • Energy cycles, scale interactions and physical-biological coupling: from ocean turbulence < 1 km, to large eddies > 100 km and the global ocean.
  • The economic and legal challenges of global ocean change (warming, acidification).

Marine ecosystems and biodiversity

  • Physiological and adaptation processes of marine organisms
  • Properties of marine molecules, e. g. biofilms
  • Functioning of ecosystems and food webs
  • Cumulative impacts of operating pressures and biological and physico-chemical factors on the dynamics of exploited species and communities
  • Ecological, economic, social and legal determinants of the development of human activities such as fishing or aquaculture.

Still unexplored oceanic depths

  • Dynamics of deep ocean depths and margins, associated seismic risks, and mineral resource formation
  • Dynamics of the Earth’s mantle and the growth of continents
  • Economic and legal issues related to ocean domains
  • Microorganisms in extreme environments in deep waters and hydrothermal springs

The coast, a complex and fragile interface

  • Physical processes in the coastal domain and at the land-sea interface, including interactions with the atmosphere
  • Coastal territories, their dynamics and vulnerabilities, both physical (remote sensing, geomatics approaches) and human (evolution of societies, uses)
  • Analysis and evaluation of public policies and development of tools and scenarios to support collective choices for coastal development.
