Science and sailing to collect environmental data during the Vendée Globe race

Building on their previous collaboration during the Vendée Globe 2024, Oliver Heer Ocean Racing and the Swiss Polar Institute renewed their partnership to place world-leading Swiss science on Oliver Heer’s racing sailing yacht IMOCA 60. This new cutting-edge data collection campaign will take place during both the training and racing phases of the Vendée Globe challenge between 2026 and 2029.

Using cutting-edge science to collect vital ocean data

As a major regulator of the global carbon and energy cycle, the Southern Ocean represents one of the key modulators of the global climate system. The Vendée Globe race and campaign are a unique opportunity for science to access data in understudied yet critical ocean regions.

"The extreme environment of the Southern Ocean still holds many mysteries – especially with regard to its role as a sink for atmospheric CO2. With these novel measurements, we will be able to unlock some of these."

A unique Swiss scientific campaign

Although similar oceanographic measurements were carried out by competing sailing yachts, offering inter-comparability and quality control opportunities, the uniqueness of the Swiss science campaign includes:

  • Oceanographic measurements using instruments developed and tested for implementation on sailing yachts. Measurements typically include parameters such as temperature, salinity and dissolved CO2 concentrations.
  • Study of "marine extreme events", notably harmful impacts on marine organisms and ecosystems.
  • Integration of the collected data into scientific publications, including open access data repositories.
  • Swiss-wide collaboration by leading Swiss science groups at ETH Zurich, the University of Bern and the University of Lausanne coordinated by the Swiss Polar Institute.

The instruments

To carry out the measurements, an OceanPack RACE® underway system manufactured by the German company subCtech has been installed and fitted with the following additional options:

  • RACE CO2 auto-calibration
  • RACE Thermosalinograph
  • RACE GPS marine receiver

This system automatically samples ocean water to measure CO2 concentration, chlorophyll, water temperature, salinity as well as atmospheric pressure.

Oliver Heer Ocean Racing

Oliver Heer Ocean Racing was established in April 2022 to become a global IMOCA 60 sailing team with Swiss roots. Managed and skippered by Oliver Heer, the objective is to compete again in the Vendee Globe, the solo, non-stop, unassisted round-the-world race that takes place every four years, with the next edition starting in November 2028.

Learning content for younger generations

In collaboration with Oliver Heer and the scientists from ETH Zurich, University of Bern and University of Lausanne, the Swiss Polar Class educational programme developed a series of modules with learning content destined to primary schools. Available in French and German, this series presented a novel way to better understand the role oceans play in global climate while following the 2024-2025 edition of the Vendée Globe, the ultimate solo sailing challenge circumnavigating Antarctica.

The ocean teaching series “Cap au Sud / Segelrennen um die Antarktis” is tailored to primary classes (5H to 8H / 3rd to 6th grade). The various chapters cover the history of human exploration of Antarctica, the importance of ocean currents, ocean life, the role of the Southern Ocean in global climate, and its transformations due to anthropogenic activities. The content continues to be freely accessible on Swiss Polar Class' website.
