Within the framework of the Earth Observatory at IUEM (OSU-IUEM), the Geosciences Ocean Laboratory participates in national observation services in the marine and terrestrial fields, particularly in Brittany.

High-sea observation

The laboratory maintains two hydroacoustic observatories (hydrophone networks) in high seas for an acoustic monitoring of the oceanic seismicity and large marine mammals :

  • OHA-SIS-BIO in the Southern Indian Ocean
  • HYDROBS-MOMAR in the Atlantic Ocean (south of the Azores)
