#MarineWildlife - Marine scientists have found new discoveries after returning to Galway Port, having spent three weeks at sea investigating Ireland's deep ocean territory 300 miles off the west coast. The deep sea expedition involved the Marine Institute's remotely operated vehicle (ROV) Holland 1 onboard the Commmissioners of Irish Lights ILV Granuaile.

The high definition ROV-mounted video captured a number of 'firsts' in Irish waters, including a species of octocoral of the genus Corallium, which grows into huge fans with a delicate porcelain-like skeleton, and a species of black coral different to others described to date, which may prove to be an entirely new species.

The survey confirmed Irish deep-waters as a haven for these rare and delicate deep-sea black corals. The team of scientists also reported areas of potential 'sponge reef' on the Rockall Bank, a highly unusual accumulation of living and dead sponges forming a complex habitat for many other creatures. Such formations are very rare and have previously only been recorded in Canadian waters.

Cold water coral reefs are ecosystems that host a diverse range of marine animals including sea fans, sponges, worms, starfish, crustaceGorgonocephalus - An Ophiuroid Basket starans and a variety of fish species, making them vitally important habitats for marine biodiversity. These fragile deepwater reefs are commonly associated with topographic features subject to strong bottom currents, for example continental margins, seamounts and mid-ocean ridges, because as filter feeders, the corals depend on suspended food particulate matter. The high resolution bathymetric dataset acquired as part of the national seabed mapping programme –Integrated Mapping For the Sustainable Development of Ireland's Marine Resource (INFOMAR) - was used to target potential locations of reef habitat for this survey by identifying specific seabed morphological features likely to support cold water coral. The last two decades have seen a dramatic increase in our understanding of the cold water coral reef ecosystems, their susceptibility to environmental change, and their low resilience to human impact.

Chief Scientist on the SeaRover survey, David O'Sullivan, Marine Institute said: "We are very pleased to discover what appear to be new coral species and a rare sponge reef, neither of which have been previously documented in Irish waters. These sensitive habitats are very important and this study is key to getting a better understanding of Irelands' deep sea. Our key objective is to discover, protect and monitor Ireland's rich offshore marine biodiversity so we can manage our marine resources effectively. Without a knowledge of what lives on our seabed we are at risk of never fully understanding and appreciating Ireland's invaluable marine environment."

Dr Kerry Howell, Plymouth University said: "This is the first time I have seen a sponge reef like this in nearly 20 years of studying the deep NE Atlantic. This is an important find. Sponges play a key role in the marine ecosystem providing habitat for other species and recycling nutrients. They may even be a source of new antibiotics. These new data will help ROV Holland 1. Picture Credit Aodhan Fitzgeraldus to better understand where and why these reefs occur."

Prof. Louise Allcock, NUI Galway, who is funded by Science Foundation Ireland and the Marine Institute to study the pharmaceutical potential of deep-sea corals and sponges added: 'This project highlights collaboration and cooperation between Irish and international marine scientists, helping us to further our understanding of these sensitive ecosystems and has also been able to provide training opportunities and sea-going experience for young scientists.

The 'SeaRover' survey is the second of three planned expeditions jointly funded by the Irish Government and the EU's European Maritime and Fisheries Fund (EMFF). The cross government initiative is supported by the Department of Agriculture, Food and Marine, Department of Culture, Heritage and Gaeltacht, and Department of Communications, Climate Action and Environment (DCCAE) as part of the Marine Institute's implementation of the Marine Biodiversity scheme.

Survey operations were coordinated and led by the DCCAE funded INFOMAR programme, which is a joint venture between the Geological Survey Ireland and the Marine Institute. This year's expedition extended the habitat exploration area to the Rockall Bank, the farthest offshore extent of Ireland's Economic Exclusive Zone. Scientific experts onboard to witness the exciting findings were from the Marine Institute, National Parks and Wildlife Service, National University of Ireland Galway and Plymouth University.

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.
