#Microplastic - The West of Ireland is one of only three sites sampled out of 75 during the Volvo Ocean Race with no trace of microplastic particles.

South of Australia and east of Argentina were the other sites found clear of microplastic in findings that give a clear mandate for positive and decisive action from national governments, international organisations, business and individuals to stop plastic polluting our seas.

The most recent data collected, before the race finale in The Hague, by scientific devices on board Team AkzoNobel and Turn the Tide on Plastic found particularly high levels of microplastics — 224 particles per cubic metre — in Skagerrak, a 150-mile strait that runs between Norway, Sweden and Denmark where the outflow from the Baltic Sea meets the Atlantic Ocean.

The highest levels of microplastic — 349 particles per cubic metre — were found in a sample taken in the South China Sea that feeds into the Kuroshio Current and the North Pacific Gyre.

The second highest, at 307 particles per cubic metre, came close from the point where the Mediterranean Sea and Atlantic Ocean meet at the Strait of Gibraltar.

Even close to Point Nemo, the furthest place from land on Earth, where the nearest humans are on the International Space Station, between nine and 26 particles of microplastic per cubic metre were recorded.

The seawater samples were collected during the course of the 45,000-nautical-mile, eight-month race which passed six continents and 12 landmark host cities. The race began in Alicante last October, finishing in The Hague in June.

Anne-Cecile Turner, sustainability programme leader for the Volvo Ocean Race, said: “We have used a sporting event to collect groundbreaking scientific data to provide a global map of microplastics concentrations — even finding them in some of the remotest places on Earth. 


“Our ambition is that the data will provide a new benchmark for our understanding of the spread of these ubiquitous particles and offer a template for future scientific methodology.

“With the continuation of the sustainability programme, we will continue our mission to inspire, engage and act as a pioneer, with the aim of restoring ocean health.”

Dr Toste Tanhua of the GEOMAR Institute for Ocean Research Kiel, funded by the Cluster of Excellence Future Ocean, analysed the preliminary microplastics data at their laboratory in Kiel, Germany.

The data has since been uploaded to a National Oceanic and Atmospheric Administration (NOAA) database where scientists are able to access it open source.

Dr Tanhua said the Volvo Ocean Race Science Programme “has contributed enormously to the understanding of microplastic contribution around the world, and has contributed to a global map of CO2 uptake by the oceans. The race has showed that the race yachts and sailors can be excellent science supporters.”

The boats also collect other oceanographic data measurements including temperature, dissolved CO2, salinity and algae content (as chlorophyll a) that gives an indication of levels of ocean health and acidification and supports quantification of the ocean’s uptake of carbon dioxide.

In parallel, 30 scientific drifter buoys deployed during the race are transmitting data that is essential for forecasting of weather and climate changes, in both the short and long term. This is being utilised by the World Meteorological Organisation and UNESCO’s Intergovernmental Oceanographic Commission.

The Volvo Ocean Race Science Programme is funded by Volvo Cars, which is donating €100 from the first 3,000 sales of the new Volvo V90 Cross Country Volvo Ocean Race edition to support the initiative.

Microplastics are often invisible to the naked eye and can take thousands of years to degrade. By collecting information on their levels, the science programme is helping scientists gain insight into the scale of plastic pollution and its impact on marine life.

To build upon the programme’s sustainability achievements, it will be embedded at the heart of the race going forward. And in the run up to the next edition, the programme will continue to organise a range of international Ocean Summits, further expand the education programme and continue to pioneer a scientific programme focussing on ocean plastic.

It will also collaborate with a range of innovative partners, including 11th Hour Racing and UN Environment, to help deliver a lasting legacy and drive real change for a healthy planet.

Since the end of the latest race, the sustainability programme convened a workshop with key global stakeholders from science, academia, the private sector and other institutions, including UN Environment and Mirpuri Foundation, to identify the gaps to fill in order to advance our understanding of these issues and to align our missions.

Fiona Ball, head of responsible business at Sky Ocean Rescue, said: “The data that Turn the Tide on Plastic collected throughout Volvo Ocean Race highlights the critical state of our oceans. By supporting the Turn the Tide on Plastic yacht, Sky Ocean Rescue aims to raise awareness and inspire everyone to make simple, everyday changes to stop our oceans from drowning in plastic. We can all play our part and turn off the plastic tap, now is the time for fundamental change to protect our planet.”
