LEGOS (Laboratory of Space Geophysical and Oceanographic Studies) is a joint research unit (UMR5566) under the supervision of CNES, CNRS, IRD, and UT3 at the Midi-Pyrénées Observatory in Toulouse, France.

The LEGOS research and teaching scientific fields include oceanography and the water cycle in the broadest sense, with the physics of the oceanic, hydrological, cryospheric and atmospheric components, including coastal and climatic components, as well as marine biogeochemistry and geochemistry.

The LEGOS teams are described in the Research Teams tab. They cover the following three fields of investigation, many projects being carried out within Cross-cutting themes :

  • Physical oceanography and interfaces with the continental water cycle: meso- and sub-mesoscale turbulence, the continent-ocean continuum, continental freshwater surface stocks and flows, vulnerable deltaic regions in relation to societies, sandy coastline with the evolution of the coastline and fine bathymetry and associated very fine scale processes, internal and external ocean tides.
  • Marine biogeochemistry: the productive systems of Eastern Boundary Upwellings and Oxygen Minimum Zones, trace element cycles and their insights into physical, biological and geochemical processes.
  • Mechanisms of global change and its regional signatures: global water cycle variations and their response to current climate warming, ocean-atmosphere-wave interactions, ice studied from space and tropical ocean dynamics.

In addition, several Observation Services and working groups allow the lab know-how to be shared, capitalised and disseminated.
