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.

Marine Protected Areas (MPAs) - FAQS

Marine protected areas (MPAs) are geographically defined maritime areas where human activities are managed to protect important natural or cultural resources. In addition to conserving marine species and habitats, MPAs can support maritime economic activity and reduce the effects of climate change and ocean acidification.

MPAs can be found across a range of marine habitats, from the open ocean to coastal areas, intertidal zones, bays and estuaries. Marine protected areas are defined areas where human activities are managed to protect important natural or cultural resources.

The world's first MPA is said to have been the Fort Jefferson National Monument in Florida, North America, which covered 18,850 hectares of sea and 35 hectares of coastal land. This location was designated in 1935, but the main drive for MPAs came much later. The current global movement can be traced to the first World Congress on National Parks in 1962, and initiation in 1976 of a process to deliver exclusive rights to sovereign states over waters up to 200 nautical miles out then began to provide new focus

The Rio ‘Earth Summit’ on climate change in 1992 saw a global MPA area target of 10% by the 2010 deadline. When this was not met, an “Aichi target 11” was set requiring 10% coverage by 2020. There has been repeated efforts since then to tighten up MPA requirements.

Marae Moana is a multiple-use marine protected area created on July 13th 2017 by the government of the Cook islands in the south Pacific, north- east of New Zealand. The area extends across over 1.9 million square kilometres. However, In September 2019, Jacqueline Evans, a prominent marine biologist and Goldman environmental award winner who was openly critical of the government's plans for seabed mining, was replaced as director of the park by the Cook Islands prime minister’s office. The move attracted local media criticism, as Evans was responsible for developing the Marae Moana policy and the Marae Moana Act, She had worked on raising funding for the park, expanding policy and regulations and developing a plan that designates permitted areas for industrial activities.

Criteria for identifying and selecting MPAs depends on the overall objective or direction of the programme identified by the coastal state. For example, if the objective is to safeguard ecological habitats, the criteria will emphasise habitat diversity and the unique nature of the particular area.

Permanence of MPAs can vary internationally. Some are established under legislative action or under a different regulatory mechanism to exist permanently into the future. Others are intended to last only a few months or years.

Yes, Ireland has MPA cover in about 2.13 per cent of our waters. Although much of Ireland’s marine environment is regarded as in “generally good condition”, according to an expert group report for Government published in January 2021, it says that biodiversity loss and ecosystem degradation are of “wide concern due to increasing pressures such as overexploitation, habitat loss, pollution, and climate change”.

The Government has set a target of 30 per cent MPA coverage by 2030, and moves are already being made in that direction. However, environmentalists are dubious, pointing out that a previous target of ten per cent by 2020 was not met.

Conservation and sustainable management of the marine environment has been mandated by a number of international agreements and legal obligations, as an expert group report to government has pointed out. There are specific requirements for area-based protection in the EU Marine Strategy Framework Directive (MSFD), the OSPAR Convention, the UN Convention on Biological Diversity and the UN Sustainable Development Goals. 

Yes, the Marine Strategy Framework directive (2008/56/EC) required member states to put measures in place to achieve or maintain good environmental status in their waters by 2020. Under the directive a coherent and representative network of MPAs had to be created by 2016.

Ireland was about halfway up the EU table in designating protected areas under existing habitats and bird directives in a comparison published by the European Commission in 2009. However, the Fair Seas campaign, an environmental coalition formed in 2022, points out that Ireland is “lagging behind “ even our closest neighbours, such as Scotland which has 37 per cent. The Fair Seas campaign wants at least 10 per cent of Irish waters to be designated as “fully protected” by 2025, and “at least” 30 per cent by 2030.

Nearly a quarter of Britain’s territorial waters are covered by MPAs, set up to protect vital ecosystems and species. However, a conservation NGO, Oceana, said that analysis of fishing vessel tracking data published in The Guardian in October 2020 found that more than 97% of British MPAs created to safeguard ocean habitats, are being dredged and bottom trawled. 

There’s the rub. Currently, there is no definition of an MPA in Irish law, and environment protections under the Wildlife Acts only apply to the foreshore.

Current protection in marine areas beyond 12 nautical miles is limited to measures taken under the EU Birds and Habitats Directives or the OSPAR Convention. This means that habitats and species that are not listed in the EU Directives, but which may be locally, nationally or internationally important, cannot currently be afforded the necessary protection

Yes. In late March 2022, Minister for Housing Darragh O’Brien said that the Government had begun developing “stand-alone legislation” to enable identification, designation and management of MPAs to meet Ireland’s national and international commitments.

Yes. Environmental groups are not happy, as they have pointed out that legislation on marine planning took precedence over legislation on MPAs, due to the push to develop offshore renewable energy.

No, but some activities may be banned or restricted. Extraction is the main activity affected as in oil and gas activities; mining; dumping; and bottom trawling

The Government’s expert group report noted that MPA designations are likely to have the greatest influence on the “capture fisheries, marine tourism and aquaculture sectors”. It said research suggests that the net impacts on fisheries could ultimately be either positive or negative and will depend on the type of fishery involved and a wide array of other factors.

The same report noted that marine tourism and recreation sector can substantially benefit from MPA designation. However, it said that the “magnitude of the benefits” will depend to a large extent on the location of the MPA sites within the network and the management measures put in place.
