Marine Institute chemists who specialise in biotoxins have won a significant international sustainability award for their work.

The Biotoxin Chemistry team who work within the Marine Environment and Food Safety Services (MEFSS) section of the Marine Institute were recently awarded the highest level (Green) of My Green Lab (MGL) certification.

MGL is a non-profit organisation and a globally recognised leader in the ‘green lab’ movement. The MGL programme seeks to reduce the environmental impact of laboratories in four key areas — energy, water, waste and chemical use — through a combination of organisational initiatives and behaviour change.

The aim is to empower scientists to make choices that not only benefit their work but also the environment and communities around them.

The Biotoxin Chemistry team are the second laboratory within the Marine Institute to be awarded MGL certification, with the Newport facility also being certified earlier this year.

‘The Biotoxin Chemistry team’s dedication exemplifies the institute’s commitment to environmental responsibility’

As part of the MGL certification process, the Biotoxin Chemistry team enrolled in 2023 International Freezer Challenge and won the Top Small Lab Award (Government Sector).

This year, 1,991 laboratories across 170 different research institutions, representing 27 countries took part in the challenge, resulting in an energy reduction of an estimated 20.7 million kWh over the past year.

The team comprising seven staff made great efforts to incorporate a cold-storage management plan involving clearing out and cleaning fridges and freezers. Their endeavors resulted in multiple units being taken out of use and an estimated energy reduction of 66.75 KWh/day (equivalent to the electricity consumption of six average Irish households).

Joe Silke, director of MEFSS, reaffirmed the Marine Institute’s commitment to sustainability: “The Biotoxin Chemistry team’s dedication exemplifies the institute’s commitment to environmental responsibility by their recent achievement of the highest level of My Green Lab certification.

“This not only showcases our commitment to reducing our laboratory's ecological footprint but also underscores the broader positive impacts that green lab initiatives can have on our working environment, finances, reputation and staff engagement.”

A postgraduate researcher is investigating the biotoxin production potential of Azadinium and related species in Irish waters, particularly in estuaries used for shellfish aquaculture such as Killary Harbour and Bantry Bay.

Stephen McGirr — a PhD candidate at the Institute of Technology Sligo and a Cullen Fellow at the Marine Institute — is studying Azadinium, a planktonic single-celled plant that lives in marine waters around Ireland.

Under certain conditions, Azadinium produces biotoxins which can build up in shellfish that feed on them. If eaten by humans, this can lead to shellfish poisoning.

Understanding more about the biology of this species would help both the shellfish aquaculture industry and protect human health.

“The genus Azadinium was first linked to incidents of shellfish poisoning in the 1990s and both toxic and non-toxic forms of the Azadinium species have since been identified in Irish waters,” McGirr says.

“More knowledge of the biology of the species is needed to support monitoring efforts currently underway to assist the aquaculture industry.”

Ireland’s aquaculture industry employed 1,925 people on 288 aquaculture production units, according to Bord Iascaigh Mhara’s Business of Seafood Report 2018. In 2018 it is estimated that Ireland produced 24,200 tonnes of farmed shellfish valued at €56 million.

“Aquaculture is a valuable industry to our national economy as well as for many of Ireland's coastal communities,” McGirr adds.

“The closure of aquaculture production sites due to biotoxins produced by organisms such as Azadinium impacts the industry and can also be detrimental to local economies.”

Stephen’s research supports the Marine Institute's National Phytoplanton Monitoring Programme, which monitors phytoplankton populations and dynamics around the Irish coastline.

McGirr says the Marine Institute’s Cullen Fellowship Programme is giving him the opportunity to learn and develop his skillset, working alongside scientists who are experts in their field, as well as gaining hands-on experience using state-of-the art equipment in the Institute's laboratories.

“I have joined two surveys on the RV Celtic Voyager along the south and western coastline of Ireland to collect both water column and sediment samples for our analyses.

“I have also presented my research at international conferences, including the International Conference on Molluscan Shellfish Safety held in Galway and the International Conference on Harmful Algae, held in Nantes, France.”

McGirr is currently focusing his efforts on translating the product of his research into articles for peer-reviewed scientific journals. His research supervisors are Joe Silke, Marine Institute and Dr Nicolas Touzet, IT Sligo.

The Cullen Fellowship Programme builds marine research capacity and capability by equipping graduates with the skills and expertise in raising awareness about our ocean, as well as Ireland's rich marine biodiversity and ecosystems.

The programme has provided grant aid to the value of €2.06 million supporting 24 PhD and three MSc students over the last five years. The research addresses a number of the 15 research themes identified in the National Marine Research and Innovation Strategy 2017-2021.

This project (Grant-Aid Agreement No CF/15/01) is carried out with the support of the Marine Institute and funded under the Marine Research Programme by the Irish Government.

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.
