COLLECTING DATA

IMOCA sailors are racers but also ‘citizen heroes’, helping to develop our understanding of climate change.

The collection of oceanographic and atmospheric data along the course using on-board or deployed instruments are invaluable contributions to the Global Ocean Observation System (GOOS).

In 2015, the IMOCA Class signed its first partnership with Intergovernmental Oceanographic Commission (IOC) of UNESCO, during COP21 in Barcelona. Since then, collaborations with scientists have continued to grow and flourish.

The partnership took another step forward, after the United Nations declared the Ocean Decade in 2021. This laid the foundations for a new era of ocean awareness alongside the Odyssey Programme that ensures sustainable support for all ocean sciences. It is spearheaded by OceanOPS in which IMOCA plays a significant role.

How does it work?

Before each race, the Class contacts OceanOPS and its various operational partners to assess the scientific opportunities related to the race routes. OceanOPS evaluates the data needs in the relevant areas and determines which types of instruments could be installed or used to complement the Global Ocean Observing System (GOOS) database.

The Class then communicates these needs to the teams, who volunteer to collaborate with scientists.

Scientific Partners

  • Intergovernmental Oceanographic Commission of UNESCO (IOC/UNESCO)
    Role: To promote international cooperation in marine sciences among its 150 Member States to improve the management of oceans, coasts, and marine resources.

  • OceanOPS
    Role: An international center of excellence for coordinating and monitoring meteorological and oceanographic observation systems (part of the Global Ocean Observing System, GOOS).
    It coordinates and optimizes the performance of a network of 10,000 meteorological and oceanographic observation devices.

  • Ifremer
    Role: One of the world’s leading institutes in marine science and technology. It conducts research, provides expertise, and creates innovations to protect and restore the ocean, responsibly exploit its resources, share marine data, and offer new services to stakeholders.

  • Météo-France
    Role: To monitor the atmosphere and the ocean surface, forecast their developments, and disseminate the corresponding information.

  • CNES (French National Centre for Space Studies)
    Role: A public agency responsible for developing and proposing France’s space program to the French government and implementing it.

The 2024 Project

For the 2024 Vendée Globe, a shared goal of involving half of the starting fleet in collaboration with scientists has become a clear priority.

This marks the first time so many sailors have united around a collective project for ocean preservation.

Building on initiatives started in 2019 with various partners, IMOCA boats have been equipped with meteorological buoys deployed as part of the European E-Surfmar program, as well as ARGO floats under the ERIC (European Research Infrastructure Consortium) Euro-Argo program.

The Different Types of Instruments

ARGO Profiler

  • Measurements: Ocean temperature and salinity.
  • Operation: The beacon dives to a depth of 1,000 meters and drifts for nine days. On the ninth day, it descends to 2,000 meters, then resurfaces on the tenth day to transmit collected data via satellites. Measurements are taken during the ascent.
  • Benefits:
    Operational: Provides in-situ data for operational modeling (weather, oceanography).
    Climate: Tracks global thermohaline circulation and monitors regional and global changes in the ocean's heat content.

Meteorological Buoy (Drifter)

  • Measurements: Atmospheric pressure, temperature, and surface currents.
  • Operation: Drifting buoy, one of the few means to provide continuous in-situ atmospheric pressure data.
  • Global Network Status: 1,200 buoys in operation.
  • Lifespan: 2 to 5 years.
  • Benefits:
    Operational: Supplies critical data for global and regional weather forecasting.
    Climate: Used for climate research, ocean monitoring, and forecasting.

FerryBox

  • Description: Oceanographic sensor system collecting continuous surface data, both physical and biological (e.g., temperature, salinity, CO2, plankton, plastic).
  • Adaptation: Prototype designed for racing boats.
