#watersafety – Irish Water Safety is appealing to the public to take extreme care when taking part in sponsored swims. Participants can be distracted by the occasion and take chances beyond what is acceptably safe and can be left without sufficient strength to climb out of the water due to the cold. Cold winter waters can cause "cold shock" and hypothermia can set in within minutes, overwhelming the fittest of swimmers.
People organising Christmas swims should ensure that they provide comprehensive details of each event to the Irish Coast Guard and local Gardai.
Each event should have a Safety Officer appointed, who will advise those concerned on safety and have the ultimate responsibility for making decisions in relation to the swim being on or off on the day on the day dependent on weather and tidal conditions remembering that there is a new moon on the 22nd of December so there will be spring tides leading to strong tidal streams on Christmas day.
If the seas are rough and weather deteriorates, they should defer the event to a more suitable day without question and not take a chance on running the event.
Many participants will not have swum since the summer and the temperature of the water has now dropped from approximately 17°C to 10°C, therefore we advise inexperienced swimmers to wear a wetsuit.
It is a fallacy that alcohol will keep you warm when entering the water; in fact it has the reverse effect and could kill you. Irish Water Safety strongly recommends that no alcohol be taken either before the swim or after the swim and also remind people that they may be in breach of the drink driving laws when driving to or from the event.
Cold water can cause cold shock and hypothermia in minutes, because the temperature of the water at this time of year will be below 10°C. Christmas day charity swimmers occasionally remain too long in the water in a gesture of bravado and can find themselves left without sufficient strength to climb out of the water becoming unbalanced and disoriented due to them becoming hypothermic, two or three minutes is plenty of time in the water for the inexperienced. Remember shivering and teeth chattering are the first signs of Hypothermia.
Ensure that you have safe access and egress with appropriate shallow shelving or ladders as appropriate. People should be mindful that steps leading into the water might be dangerous due to the growth of algae..
Swimmers' remaining in the water for extended periods in a gesture of bravado is not acceptable. The message is "Get In, Get Out and Warm Up" and in the event of an emergency call the Coast Guard on 112.

The hidden danger of ice could be lurking right underneath your feet and you won't know it until it's too late. Scientists say it takes several weeks of freezing temperatures in order for ice to be safe enough to walk on, and even then, there are risks.

Belfast Coastguard, in warning the public about venturing out on thin ice said:

"There's no such thing as safe ice. If you do go through the ice, you could face frostbite, hypothermia and ultimately death if you are not rescued fast enough.

"If you're going out anyway in poor weather take your mobile phone with you; because it's cold out there, and you never know when you might need it in an emergency".

"Today in Northern Ireland, a dog drowned after falling through the ice at Enniskillen, Lough Erne. Remember to keep dogs on leads in danger areas, or avoid walking close to frozen lakes, rivers or ponds. Never go in the water after a dog - call the Emergency Services instead.

"If you do fall through the ice, try not to panic. You're going to take a deep breath when you go in, and you're going to suck some water in.

"You have to fight through that and that urge to panic. In that first stage, find something to hold on to whilst you're gasping and suffering from 'cold shock'. Once you get yourself calmed down, you're going to get really cold really fast. You're going to have about 10 minutes where you can actually do stuff and then your fine motor skills will start to fail, your fingers are going to be so cold, you're not going to be able to grab hold of stuff. You're going to have to pull yourself up with your elbows, your arms, and kick."

If you do fall in but are able to get out, you should roll yourself in the same direction to shore the same way you walked in because you know that area of ice is stable.

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.
