Data from the M3 and M5 buoys off the South Coast is being recovered for analysis by the Marine Institute to ascertain whether it can explain the cause of a tidal drop of 70 cms reported at Union Hall and Courtmacsherry in West Cork last Saturday afternoon.

Local people described the tide level dropping in a few minutes and then flooding back in.

There have been further reports of similar happenings on the Wexford coast and in Wales.

As Afloat reported earlier, descriptions of what happened in the area of Glandore Harbour where Union Hall is located have varied, from some people describing water levels leaving boats temporarily touching bottom where they were moored, to others who claimed the tide “came in and out several times…” and another comment: “the tide was going the wrong way…”

Amongst reports of seismological activity on Saturday were a 2.6 magnitude earthquake before noon near the Azores. That was logged at the European Mediterranean Seismological Centre.

Historical context records a 1755 earthquake off the coast of Portugal, which was reported to have caused damage on the Irish South Western coast.

Amongst suggestions for the cause is atmospheric pressure, northerly wind and known water actions at the areas involved. Oceanography sources have tended to discount the incidents in West Cork being associated with the seismic action off Portugal. “It would not be big enough to have that effect,” I was told. “Rare, unusual, possibly driven by a number of factors that may lead to an unusual event, but in this case the cause is so far not clear, so examining date from the buoys at sea may help to indicate it.”

No other Cork coastal areas have reported anything similar.

A Marine Institute statement said: "An unusual tidal event was observed on Saturday 18th June 2022 at Union Hall (West Cork) at 14.40 (UTC) with a low water of -2.629m measured by the Irish Tide Gauge Network.”

Water Safety Ireland has issued a warning over the dangers of strong tidal streams tides over the Christmas period.

On St. Stephen’s Day there will be a new moon. A new moon will increase the range of our tides causing higher and lower tides. This will expose large areas of beach and rocks which we don’t see during neap tides. Many people enjoy exploring these new areas of beach and in particular, enjoy picking shellfish to eat.

As you walk shorelines, keep a close eye on new moon tidal advances and carry your mobile phone in case you are cut off. 

"On St. Stephen’s Day there will be a new moon"

The risk of becoming stranded as the tide advances can quickly leave people cut off from the shore which is why people should carry their mobile phone and call 112 if required.

All those swimming, boating, surfing, or diving should be aware of stronger tidal streams around our coast over the Christmas period.

Swimmers need to be aware of the risks rip currents will have on our beaches. The public is encouraged to access tidal information through newspapers and online.

#fullmoon – The warm weather has brought many people out to enjoy the seaside and coastal walks, however the CEO of Irish Water Safety, John Leech is warning the public that there is a full moon tomorrow 2nd of July which is causing high spring tides which poses a higher risk of being washed in to the sea or being dragged out to sea by a rip current.

A danger foreseen can avoided...

Walkers should remain alert and stay well away from the edge of ordinarily familiar coastal walks due to the risk being washed in by large Atlantic swells. Those walking on our beaches and collecting sea shells should be alert to a fast advancing tide and of being stranded. Please carry your mobile phone and ideally in the company of others.

Anglers should be extremely vigilant, three having drowned so far this year. Atlantic swells present a clear danger to shoreline anglers and a substantial distance from the edge should be maintained at all times and always wear a lifejacket.

Swimmers be awareof rip currents, especially on surfing beaches, never swim against this narrow current of water flowing away from a beach. Instead, swim parallel to the shore, out of the narrow current, then swim back to shore at an angle. Details at http://www.iws.ie/beach/rip-current-safety.328.html

Divers completing drift dives need to carefully calculate the rate of drift and ensure that the dive boat maintains contact with their divers throughout the dive.

If an emergency develops don't delay - Call 112 and ask for Coast Guard.

The UK Coastguard is warning coastal visitors to check tide times after multiple incidents around the country where people have been cut off by the tide.

Coastguard coordination centres have dealt with at least eight different incidents this afternoon involving a total of 16 people who have become cut off by incoming tides at different places around the coast.

In Pembrokeshire, six people were rescued from the water by Little Haven RNLI lifeboat at Setlands Beach near Broad Haven and at St Dogmaels the Cardigan RNLI inshore lifeboat recovered a woman who was stuck thigh deep in mud.

Humber Coastguard was alerted to two people and their dogs trapped by a fast rising tide near Bridlington.  They were unsure of their location and as rescue units began searching for them, the couple were fortunately spotted by Hornsea Rescue lifeboat who recovered them from the water in a distressed condition.

Mike Bill, Coastguard Watch Manager at Humber Coastguard says,

"Coastguards are warning people at the coast to check tide times to ensure you are not caught out.  Talk about how the tides work with your family and make sure everyone understands how tides work and what the dangers are when walking at the coast."

Four teenagers were rescued in Co Down last weekend when they were cut off by the tide, the News Letter reports.
The teens were caught up to their shoulders in water at Ardilea on Saturday evening when they were retrieved by a former volunteer coastguard who lives nearby.
The group were met at the shore by the South Down Coastguard Rescue Team and NI Ambulance Service paramedics and taken to hospital showing signs of hypothermia.
Meanwhile, on Friday night RNLI Bangor lifeboat rescued a young girl stranded on a rock near Groomsport after a call from a member of the public.
“With waves breaking around the knees of the frightened child it was paramount that she be brought ashore as quickly as possible," said a coastguard statement.
The girl was treated by waiting paramedics at the shore.

For all you need on the Marine Environment - covering the latest news and updates on marine science and wildlife, weather and climate, power from the sea and Ireland's coastal regions and communities - the place to be is Afloat.ie.

Coastal Notes

The Coastal Notes category covers a broad range of stories, events and developments that have an impact on Ireland's coastal regions and communities, whose lives and livelihoods are directly linked with the sea and Ireland's coastal waters.

Topics covered in Coastal Notes can be as varied as the rare finding of sea-life creatures, an historic shipwreck with secrets to tell, or even a trawler's net caught hauling much more than just fish.

Other angles focusing the attention of Coastal Notes are Ireland's maritime museums, which are of national importance to maintaining access and knowledge of our nautical heritage, and those who harvest the sea using small boats based in harbours where infrastructure and safety pose an issue, plying their trade along the rugged wild western seaboard.

Coastal Notes tells the stories that are arguably as varied as the environment they come from, and which shape people's interaction with the natural world and our relationship with the sea.

Marine Wildlife

One of the greatest memories of any day spent boating around the Irish coast is an encounter with Marine Wildlife. It's a thrill for young and old to witness seabirds, seals, dolphins and whales right there in their own habitat. And as boaters fortunate enough to have experienced it will testify, even spotting a distant dorsal fin can be the highlight of any day afloat. Was that a porpoise? Was it a whale? No matter how brief the glimpse, it's a privilege to share the seas with Irish marine wildlife.

Thanks to our location in the North Atlantic, there appears to be no shortage of marine life to observe. From whales to dolphins, seals, sharks and other ocean animals, the Marine Wildlife category documents the most interesting accounts around our shores. And we're keen to receive your observations, your photos, links and video clips, too!

Also valuable is the unique perspective of all those who go afloat, from coastal sailing to sea angling to inshore kayaking to offshore yacht racing, as what they encounter can be of great importance to organisations such as the Irish Whale and Dolphin Group (IWDG). Thanks to their work we now know we share the seas with dozens of species who also call Ireland home. But as impressive as the list is, the experts believe there are still gaps in our knowledge. Next time you are out on the ocean waves, keep a sharp look out!

Weather

As an island in the North Atlantic, Ireland's fate is decided by Weather more so than many other European countries. When storm-force winds race across the Irish Sea, ferry and shipping services are cut off, disrupting our economy. When swollen waves crash on our shores, communities are flooded and fishermen brace for impact - both to their vessels and to their livelihoods.

Keeping abreast of the weather, therefore, is as important to leisure cruisers and fishing crews alike - for whom a small craft warning can mean the difference between life and death - as it is to the communities lining the coast, where timely weather alerts can help protect homes and lives.

Weather affects us all, and Afloat.ie will keep you informed on the hows and the whys.

Marine Science

Perhaps it's the work of the Irish research vessels RV Celtic Explorer and RV Celtic Voyager out in the Atlantic Ocean that best highlights the essential nature of Marine Science for the future growth of Ireland's emerging 'blue economy'.

From marine research to development and sustainable management, Ireland is developing a strong and well-deserved reputation as an emerging centre of excellence. Whether it's Wavebob ocean energy technology to aquaculture to weather buoys and oil exploration, the Marine Science category documents the work of Irish marine scientists and researchers and how they have secured prominent roles in many European and international marine science bodies.

Power From The Sea

The message from the experts is clear: offshore wind and wave energy is the future. And as Ireland looks towards the potential of the renewable energy sector, generating Power From The Sea will become a greater priority in the State's 'blue growth' strategy.

Developments and activities in existing and planned projects in the pipeline from the wind and wave renewables sector, and those of the energy exploration industry, point to the future of energy requirements for the whole world, not just in Ireland. And that's not to mention the supplementary industries that sea power projects can support in coastal communities.

Irish ports are already in a good position to capitalise on investments in offshore renewable energy services. And Power From The Sea can even be good for marine wildlife if done properly.

Aside from the green sector, our coastal waters also hold a wealth of oil and gas resources that numerous prospectors are hoping to exploit, even if people in coastal and island areas are as yet unsure of the potential benefits or pitfalls for their communities.

Changing Ocean Climate

Our ocean and climate are inextricably linked - the ocean plays a crucial role in the global climate system in a number of ways. These include absorbing excess heat from the atmosphere and absorbing 30 per cent of the carbon dioxide added to the atmosphere by human activity. But our marine ecosystems are coming under increasing pressure due to climate change.

The Marine Institute, with its national and international partners, works to observe and understand how our ocean is changing and analyses, models and projects the impacts of our changing oceans. Advice and forecasting projections of our changing oceans and climate are essential to create effective policies and management decisions to safeguard our ocean.

Dr Paul Connolly, CEO of the Marine Institute, said, “Our ocean is fundamental to life on earth and affects so many facets of our everyday activities. One of the greatest challenges we face as a society is that of our changing climate. The strong international collaborations that the Marine Institute has built up over decades facilitates a shared focusing on our changing ocean climate and developing new and enhanced ways of monitoring it and tracking changes over time.

“Our knowledge and services help us to observe these patterns of change and identify the steps to safeguard our marine ecosystems for future generations.”

The Marine Institute’s annual ocean climate research survey, which has been running since 2004, facilitates long term monitoring of the deep water environment to the west of Ireland. This repeat survey, which takes place on board RV Celtic Explorer, enables scientists to establish baseline oceanic conditions in Irish waters that can be used as a benchmark for future changes.

Scientists collect data on temperature, salinity, water currents, oxygen and carbon dioxide in the Atlantic Ocean. This high quality oceanographic data contributes to the Atlantic Ocean Observing System. Physical oceanographic data from the survey is submitted to the International Council for the Exploration of the Seas (ICES) and, in addition, the survey contributes to national research such as the VOCAB ocean acidification and biogeochemistry project, the ‘Clean Atlantic’ project on marine litter and the A4 marine climate change project.

Dr Caroline Cusack, who co-ordinates scientific activities on board the RV Celtic Explorer for the annual survey, said, “The generation of long-term series to monitor ocean climate is vital to allow us understand the likely impact of future changes in ocean climate on ecosystems and other marine resources.”

Other activities during the survey in 2019 included the deployment of oceanographic gliders, two Argo floats (Ireland’s contribution to EuroArgo) and four surface drifters (Interreg Atlantic Area Clean Atlantic project). The new Argo floats have the capacity to measure dissolved ocean and biogeochemical parameters from the ocean surface down to a depth of 2,000 metres continuously for up to four years, providing important information as to the health of our oceans.

During the 2019 survey, the RV Celtic Explorer retrieved a string of oceanographic sensors from the deep ocean at an adjacent subsurface moored station and deployed a replacement M6 weather buoy, as part of the Irish Marine Data Buoy Observation Network (IMDBON).

Funded by the Department of Agriculture, Food and the Marine, the IMDBON is managed by the Marine Institute in collaboration with Met Éireann and is designed to improve weather forecasts and safety at sea around Ireland. The data buoys have instruments which collect weather and ocean data including wind speed and direction, pressure, air and sea surface temperature and wave statistics. This data provides vital information for weather forecasts, shipping bulletins, gale and swell warnings as well as data for general public information and research.

“It is only in the last 20 years, meteorologists and climatologists have really began to understood the pivotal role the ocean plays in determining our climate and weather,” said Evelyn Cusack, Head of Forecasting at Met Éireann. “The real-time information provided by the Irish data buoy network is particularly important for our mariners and rescue services. The M6 data buoy in the Atlantic provides vital information on swell waves generated by Atlantic storms. Even though the weather and winds may be calm around our shores, there could be some very high swells coming in from Atlantic storms.”
