What is OHIS ?

The OHIS (Océan Hauturier In Situ) research infrastructure aims to coordinate long-term observation of essential ocean variables in key regions, using targeted multi-platform measurements: on-board streams, sub-polar regions, divergent regions for floats, air-sea interface, high-precision multidisciplinary campaigns.

In 2021, when OHIS is created, it federates 4 recognized observation systems: PIRATA (Interaction océan-atmosphère dans l’Atlantique tropical), SSS (Sea surface salinity, salinité de surface), MEMO (Mammifères échantillonneurs du Milieu Océanique – Océan Austral), OVIDE (Observatory of Interannual to Decadal Variability in the North Atlantic).

As a system integrating all oceanographic disciplines, OHIS helps position France as a key player in sustainable, harmonized observation of the global ocean, capable of providing high-quality environmental data, access to solutions and services for marine researchers and users, and societal products and indicators.

In close interaction with other marine infrastructures, OHIS is a key element in supporting excellence in national marine research to better meet the needs of society and policy, in connection with the global challenges carried by the United Nations Decade of Ocean Sciences for Sustainable Development, which began on January 1, 2021.
