Voyages out as far as the edge of the Continental Shelf on the Atlantic Ocean has produced rare sightings for the Irish Whale and Dolphin Group and this August there is a chance to see the join the crew and see the whales again writes Patrick Lyne

Back in 2012 when the Celtic Mist became available to the Irish Whale and Dolphin Group we were looking at ways the boat could be used to support the work the Group does and demonstrate to people in Ireland the wealth of life that exists in Irish waters. So for three years from 2012 to 2014 we took the Celtic Mist to the shelf edge in early September. Indeed we were blessed when first arriving on the shelf edge only to be greeted by two blue whales. It took several minutes in close proximity (200m) to the whales before we believed our eyes. We had expected large whales but not those to be waiting for us. They stayed around and passed either side of the boat moving from port to starboard for what seemed like an age, before moving further away. We could manage a top speed of maybe 8 knots while blue whales could travel at up to 25 knots approximately and there was no way we could keep pace with these animals if they decided to leave us behind.

Shortly afterwards the Irish Air Corps Casa (C253) appeared and called on the radio and managed to get some excellent shots of both the Celtic Mist and the blue whales.

In 2013 had some remarkable sightings of beaked whales again in the Porcupine Seabight and while unable to confirm that the animals that passed close to the vessel in 2013, were True’s beaked whales, it seems highly probable that they were. Beaked whales are particularly difficult to study being adverse to noise and spending large periods of time underwater. The Cuvier’s beaked whale holds the record for the longest recorded dive of any cetacean of 2 hours 17 minutes while attaining a depth of 2,992m. These animals are rarely seen close to shore and when they are, they often end up stranding and dying. The deep ocean off the shelf edge is their natural habitat.

Each year has produced it’s own spectcular moments and the humpback whales off Dingle have become more and more reliable and are a feature of our trips every year. Last year we were treated to one beautiful day on the shelf edge with calm weather. It is this calm weather that always produces the best results. While whales numbers wer not spectacular they were considerable and most if not all animals were engaged in feeding. We simply allowed the boat to drift while fin whales fed in close proimity to the boat and we could see the huge jaws opening to envelope the krill underwater.

Last year we changed vessels to Jessy of Adrigole a 37 ft–yacht, the Celtic Mist being unavailable and this year we have decided to continue using Jessy but for a longer trip. We propose starting in Castletownbere and sailing to Camaret in Brittany along the shelf edge. The shelf edge between here and Brittany is some of the most dramatic in the world with drop offs from 200m down to nearly 4000m. The EEZ of the UK is slowly squeezed such that French and Irish waters will eventually meet as boundaries extend.

It is more important than ever to record the variety and abundance of Ireland’s offshore environment. While oil exploration will suffer from the current over supply, exploration rights has been granted to both Russia and France by the International Seabed Authority (ISA – not the Irish Sailing Association but a UN body based in Jamaica) in the mid-Atlantic Ridge in the North Atlantic. The marine environment is constantly under greater and greater pressure. Protection for cetaceans is critical to mainting the entire marine habitat. Reduction in large whale numbers in the Southern Ocean due to whaling did not result in an increase in their favourite prey, krill, but rather reduced krill abundance. Whale faeces enriches the ocean with iron, producing plankton blooms which start the food chain and absorb excess carbon from the atmosphere. The South West in particualr sees large numbers of tuna arrive in August and September, follwoed by French and Spanish and Irish fishing vessel as well as whales. It is important for the whales that they are able to build blubber reserves at this time, especially for the females as without sufficient reserves to sustain them during pregnancy of 11 or 12 months, the whale will abort. Recovery rates are slow with these large whales and even with protection it will be manay many decades before fin and blue whale numbers reach pre-whaling levels.

In August we will embark again to try and find calm weather on the shelf edge and hope to add significantly to the picture of cetaceans in Irish waters in a time when they are at their most abundant. It is a unique opportunity for people to become involved with our marine mega fauna in a way not available elsewhere and to add to knowledge of the area. The charge to crew of €1310 allows the work to take place and is an enriching experience and an education. If interested contact Patrick Lyne by email ([email protected]).

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.
