Microfibres ‘Rife in Europe’s Seas’ According to Samples From The Ocean Race Europe

New research from The Ocean Race Europe has found microplastics, and in particular microfibres, to be prevalent across the length and breadth of Europe.

All 36 water samples collected around the continent — including in the Baltic Sea, the English Channel, along the Atlantic coastline and in the Mediterranean Sea — were found to contain microfibres.

These tiny plastic fibres enter the environment from manufacturing, washing and wearing synthetic clothes. Fibres also originate from car tyres, ending up in the sea after heavy rain and run-off, as well as from ​​fragmented fishing gear and lines.

The data, which was captured by sailing teams competing in the first edition of The Ocean Race Europe, found that on average Europe’s seas contain 139 microplastic particles per cubic meter.

Most of these particles (83%) are microfibres, with the remaining being fragments from the degradation of larger plastic items such as plastic bottles, packaging and microbeads in toiletries. Three of the samples (two from the Channel and one from the Mediterranean Sea) contained microfibres exclusively.

The Ocean Race measured microplastics in the last edition of the round-the-world race in 2017-18 in a pioneering move that combined racing and science. This summer, the race teamed up with scientific bodies GEOMAR Helmholtz Centre for Ocean Research Kiel and Utrecht University to discover more about the source of the microplastics by analysing whether they are fibres or fragments.

Dr Aaron Beck, senior scientist at GEOMAR Helmholtz Centre for Ocean Research Kiel, who coordinated the analysis of the microplastic samples, said: “The data clearly show that microplastics are pervasive in the ocean and that, surprisingly, the major component of these microplastics are microfibres.

“Previous research has typically focused on detecting fragments, rather than fibres, so this new data is significant and highlights the value of collaborations with partners like The Ocean Race that help us better define the make-up and distribution of microplastics in the surface of the ocean.”

The Ocean Race says its data is contributing to the development of a map of plastic in the ocean and helping inform understanding of how microplastics transfer into marine ecosystems. Microfibres are the type of microplastic that are most frequently eaten by marine species and therefore of concern for ocean biodiversity.

The Ocean Race Europe took place in May and June 2021, starting in Lorient in North West France and finishing in Genova, Italy.

Data was collected over a six-week period in May and June 2021 during The Ocean Race Europe and its prologue. Two teams, Ambersail-2 and AkzoNobel Ocean Racing, carried scientific equipment onboard to capture samples of microplastics as they raced, while a third boat, 11th Hour Racing Team, took measurements of carbon dioxide (CO2), sea temperature, PH levels and salinity, which are key indicators of climate change.

The data gathered in the race showed the Baltic Sea to have the highest levels of microplastics in Europe, with 230 particles found per cubic metre, on average double the amount found in the Mediterranean (112 particles per cubic metre) which is considered a hotspot for plastic pollution.

Dr Beck said: “The high abundance of microplastic in the Baltic Sea compared to the Mediterranean Sea is unexpected. Factors such as the time of year that the data is collected can have an impact on the distribution of microplastics. The more data we can gather, from different areas and seasons, the better we can understand the source of the plastics and where they end up.”

The ocean plays a critically important role in climate regulation. It has absorbed over 90% of man-made excess heat since the 1970s and absorbs a quarter of human made carbon CO2, helping to effectively mitigate climate change. However, this absorption causes the ocean to become more acidic, which has an adverse effect on marine life.

Measurements of dissolved CO2 captured during The Ocean Race Europe by 11th Hour Racing Team have been submitted to the Surface Ocean Carbon Dioxide Atlas (SOCAT), which provides data for the Global Carbon Budget, a yearly assessment of CO2 that informs targets and predictions for carbon reduction.

It is vital that scientists understand the levels of CO2 in the ocean to form an accurate budget and keep the world on track to stay within the Paris Agreement goal of limiting global warming to below 1.5 degrees Celsius.

The CO2 data were also analysed by EuroSea, a European Commission-funded programme that improves the ocean observing and forecasting systems. Carbon dioxide levels were found to be highest in the Mediterranean, as a consequence of warm temperatures and very little wind.

Simon Weppe, science lead at The Ocean Race said: “Climate change and plastic pollution have, in mere decades, caused a drastic decline in the health of the ocean. Through The Ocean Race’s unique collaboration between sailors and ocean research organisations, we are helping to grow understanding of these dire issues.

“The more we know of the scale of these problems the better placed we are to take action to combat them; this is crucial, as the state of the seas and the fate of the planet are completely interlinked.

"It's vital that governments act on the scientific evidence to protect and restore our ocean and all that depends on it. The race for the ocean is a race we must win.”

The Ocean Race Europe scientific data collection activity was endorsed by the UN Decade of Ocean Science for Sustainable Development, a global movement to unlock the knowledge needed to reverse the cycle of decline in ocean health and create improved conditions for sustainable development of the ocean.

The Ocean Race’s innovative science programme has been developed in collaboration with 11th Hour Racing, premier partner of The Ocean Race and founding partner of the Racing with Purpose sustainability programme.
