The Royal Society for the Protection of Birds (RSPB) anticipates that puffins will benefit from the closure last month of the industrial fishery for sand eels in the North Sea and Scottish waters.

The closure of the fishery from March 26th is coming into place in time for the breeding season for puffins, the RSPB says.

“Sandeels, a main source of food for puffins and their chicks, are a vital link in the food chain for seabirds, as well as some fish species and sea mammals, yet their numbers have been rapidly declining due to climate change and overfishing,” it says.

“The charismatic birds have already been delighting visitors in recent weeks as they arrive back at Rathlin Island, Northern Ireland, RSPB South Stack, North Wales, RSPB Sumburgh Head in Shetland, and at RSPB Bempton Cliffs, Britain’s largest mainland seabird colony,” it says.

Dave O’Hara, senior site manager at RSPB Bempton Cliffs, said it is “home to one of the UK's top wildlife spectacles”.

“But these populations of seabirds are at the forefront of the climate emergency, and they are in significant decline. Puffins’ resilience is being pushed to the limit, which is why we can breathe a sigh of relief that industrial sandeel fishing in UK waters has now been ended,”he said.”

The most recent *seabird census, Seabirds Count, published in November 2023, suggests that around one in four puffins have been lost across Britain since 2000.

“It's predicted that the UK's puffin population could plunge 90% by 2050 if global warming is unchecked. Facing threats to both their nesting sites and their food supply, the climate crisis is sadly only making things worse for these clowns of the sea,”it says.

Puffins will continue arriving throughout April, staying to raise their pufflings (one egg is laid per puffin), and then leaving at the end of July.

The tiny birds winter out at sea, and are widely dispersed out in the North Sea and wider Atlantic Ocean.

Extinction threatens 48 species living in the Irish marine environment, including fish, crustaceans, shellfish and invertebrates, according to the new National Biodiversity Action Plan.

“It is imperative that we arrest these declines and start the process of regeneration,” the authors of the action plan state.

The fourth national biodiversity action plan was published yesterday by Minister for Heritage Malcolm Noonan.

The new plan has been placed on a statutory footing for the first time, and it also commits to enacting and implementing comprehensive legislation on marine protected areas.

The plan notes that in Ireland, almost a third of EU-protected species and 85% of EU-protected habitats are in unfavourable status.

It says that over half of native Irish plant species have declined in the last 20 years, and 30% of semi-natural grasslands have been lost in the past 10 years.

Over 20% of breeding and 52% of key wintering bird species are reported to have short-term declining trends, it says.

Many of the issues it identifies were addressed in the report by the Citizens’ Assembly on Biodiversity Loss.

The new biodiversity action plan seeks to address a number of its key recommendations.

Its 194 actions across sea and land include commitments to deliver on obligations to conserve the most precious habitats and species, and “strategically target” efforts on invasive species.

The Fair Seas coalition of environmental groups welcomed its publication, but warned that it will only work if “every single measure is acted upon promptly”.

The seas off Wexford have been designated as a proposed new special protection area (SPA) for birds by Minister of State for Heritage Malcolm Noonan.

The new SPA adjoins eight existing SPAs designated for this area and will cover over 305,000 hectares of marine waters for a range of bird species throughout the year.

The area under the EU Birds Directive surpasses the north-west Irish Sea SPA designated for seabirds last year, Noonan said.

The Wexford designation increases the percentage of Ireland’s protected marine waters to just under the 10% for Natura designations promised by the minister under the EU Biodiversity Strategy.

It also makes that 10% milestone “realistically achievable within the current year”, he says.

“At 305,000 hectares, the seas off Wexford SPA is bigger than Co Wexford itself and the largest ever area to be protected for birds in the history of the State,” Noonan said.

“ I’m delighted to be able to announce this significant step forward for nature, and particularly for marine seabirds. This Government is working hard to ensure robust biodiversity protections, just as we are working hard to deliver on our offshore renewable energy objectives,” he said.

“ Biodiversity action and climate action must go hand in hand, and we must continue to work together to protect nature while delivering a swift transition to more sustainable and renewable forms of energy,” he said.

National Parks and Wildlife Service director general Niall Ó Donnchú said the designation represented “another determined step by Ireland to protect our marine birdlife”.

“The 20 species protected at this site are some of our rarest and most threatened birds, and these waters are a valuable feeding resource for the seabirds that return every spring to Wexford’s coastal and island colonies to breed,” he said.

“ Outside of the summer months, these relatively shallow coastal waters provide safe feeding and roosting opportunities for a range of marine birds overwintering here or on passage,” he said.

The marine waters off the coast of Co Wexford mark the boundary between the Irish and Celtic Seas, and the new SPA extends offshore along most of the county’s coast.

More detailed information about the site, including a map, a species list and a list of the activities requiring consent (ARCs) for the site, is available at www.npws.ie/protectedsites.

Objections or observations, which may only be based on scientific or ornithological grounds, can be submitted to the email address [email protected].

Bird species covered by the proposed SPA designation are: the Common Scoter, Red-throated Diver, Fulmar, Manx Shearwater, Gannet, Shag, Cormorant, Kittiwake, Black-headed Gull, Lesser Black-backed Gull, Herring Gull, Little Tern, Roseate Tern, Common Tern, Arctic Tern, Sandwich Tern, Mediterranean Gull, Puffin, Razorbill and Guillemot.

Four of the existing SPAs in this area are designated for breeding seabirds, namely Lady’s Island Lake SPA, Wexford Harbour and Slobs SPA, Keeragh Islands SPA and Saltee Islands SPA.

The Fair Seas coalition of environmental organisations said the proposed SPA should be a cause for celebration, but said that” a lack of proper community engagement, no coinciding management plans and no sign of the promised Marine Protected Area (MPA) bill is risking public trust in the process”.

Fair Seas said that “although the news is welcome, proper consultation with local fishers, industry, communities and other stakeholders is vital to ensure its success”.

The group is campaigning for “strong and ambitious MPA legislation to be introduced as a matter of priority”.

Over three-quarters of seabird species breeding in Ireland have increased, with only two species declining, according to a census just published.

The “Seabirds Count” census shows that Ireland is particularly important for species such as Roseate Tern and European Storm-petrel as 94% and 73% of the total populations breed here.

Roseate Tern, European Storm-petrel and Razorbill are some of the 17 species which have increased over the last 20 years, it says while the Kittiwake and Puffin are in decline.

It says that increasing populations of some seabird species are linked to effective conservation management measures, such as tern-wardening projects.

Seabirds Count, which has been released as a book by wildlife publishers Lynx Edicions, is said to be the most comprehensive seabird census produced to date.

It provides population estimates for the 25 regularly breeding species of Britain, Ireland, Isle of Man and the Channel Islands.

The survey took place between 2015 and 2021 and was led by the Joint Nature Conservation Committee (UK) with over 20 steering group partners.

BirdWatch Ireland and the National Parks and Wildlife Service were the key partners in Ireland.

It has found that seabirds are “doing well in Ireland with 17 species increasing and only two declining”.

“A similar pattern prevails in Northern Ireland, with four species declining and nine increasing,”it says.

“ This is in contrast to census results across the entire UK and Ireland, which show that 11 of the 21 seabird species, where there is confidence in their trends, have declined since the last census in 1998-2002,” it says.

It notes that results differ significantly by region or country, with “ encouraging trends” in Ireland for species such as the Black-headed Gull and the Arctic Tern.

At the overall census level, the Arctic Tern breeding population is in decline (35%), but the population is considered stable across the island of Ireland.

The Black-headed Gull, which breeds on inland wetlands as well as the coast, has suffered an overall decline of 26%, but this is in contrast with an analysis of Irish data, which shows increases (Ireland 84%; NI 23%, all-island 40%), it says.

Overall, Black-legged Kittiwake has declined by 42% since the last census, but the population in Northern Ireland “bucks this trend” and shows an increase of 33%, it says.

“Further south in Ireland, the population of Kittiwake is in decline (36%),” it says.

“Little appears to have changed in the colonies where they breed, so these declines are driven by changes in the marine ecosystem upon which they depend,” it suggests.

“Other main drivers for declining populations vary between species and even location, however, there are some prevalent themes,” it says.

These include predation by American mink, which may have been released onto or swum to seabird colony islands, and brown rats, which may have stowed away on boats.

“Climate change is another important factor. Adverse weather conditions are causing nest sites to be swept away and making foraging conditions more difficult,”it says.

“ Increased water temperatures reduce the availability of important food such as small fish, for example, sand eels and sprats, which leads to seabird parents not finding enough food,” it notes.

“This could be exacerbated by fish stock depletion by commercial fisheries, meaning that there is not enough food to go around during the important breeding season,” it says.

BirdWatch Ireland has welcomed the announcement of a new scheme for the protection and conservation of breeding waders.

€30 million has been set aside for the Breeding Wader EIP (European Innovation Partnership), according to the Minister of State for Heritage and Electoral Reform, Malcolm Noonan.

A sum of €22.5 million is to be invested by the National Parks and Wildlife Service, with the remaining €7.5 million coming from the Department of Agriculture, Food and the Marine.

"Waders are amongst the most threatened of all breeding birds in Ireland"

Waders are amongst the most threatened of all breeding birds in Ireland, with six of the eight regularly occurring species on the Red List of Birds of Conservation Concern in Ireland, Birdwatch Ireland says.

The six species are the curlew, lapwing, dunlin, golden plover, redshank and snipe.

Five of these species have declined by at least 50% in the last 40 years.

Curlew and lapwing have each declined by over 90% in the last 20 years and are considered to be approaching globally threatened status by BirdLife International, it says.

“Loss of breeding habitat through agricultural intensification, draining of peatlands and afforestation have all contributed to these declines, but widespread predation of nests and chicks by generalist predators such as foxes and crows have also severely impacted remaining populations in recent years,” Birdwatch Ireland says.

The organisation says it had previously recognised that a scheme underpinned by at least €30 million was required to support farmers to undertake measures to save Ireland’s breeding waders from extinction.

“ We are pleased that the Irish government has taken heed,” it said.

“The Government has been implementing measures aimed at protecting and restoring populations, for example, through the Acres Co-operation scheme and the Curlew Conservation Programmes. However, more ambitious plans are required if these iconic birds are to be saved from extinction,” it says.

“The new measures which have just been announced could make a significant difference to saving breeding waders, but must be targeted and implemented correctly,” Birdwatch Ireland chief executive officer Linda Lennon said.

“ Farmers have long wanted to act for nature but have lacked the funding to enable them to do so. This new funding stream must enable farmers to put in place habitat management measures to protect breeding waders on their land.”

“Predator control measures, including the installation of specialised fencing to exclude predators, must also be part of the solution. The effectiveness of such fencing has already been proven beyond doubt by projects implemented by BirdWatch Ireland and others and is crucial to efforts to save our breeding waders,” she said.

Over 70 per cent of marine mammals in US waters face “major threats” from climate change, a study by the National Oceanic and Atmospheric Administration (NOAA) has found.

As The Irish Examiner and Press Association report, loss of dissolved oxygen and changes to ocean chemistry will have a significant impact. The study involved more than 100 stocks of marine mammal species in US waters.

Warming ocean temperatures, shrinking polar ice, and a rise in sea levels pose severe risks, with loss of habitat and food. The study has found that large whales, including humpback and North Atlantic right whales, along with dolphins, are among the most vulnerable.

Marine mammals living in the western North Atlantic ocean, Gulf of Mexico and Caribbean Sea were the focus of the study, and the findings are published in the journal the journal PLOS One.

Birdwatch Ireland is seeking volunteers to participate in its Irish Wetland Bird Survey, which informs waterbird conservation and management in Ireland.

Individuals with a telescope and good bird identification skills are encouraged to volunteer, as there are a number of vacant sites.

There are currently over 500 Irish Wetland Bird Survey volunteers who have contributed to a substantial gathering of data since it was established in 1994.

Many of the vacant sites are small and close together, meaning one person could easily fill several of these gaps in a few short hours, it says.

Some areas which have teams of counters often need an extra pair of experienced eyes.

The 2023/24 season will be the 30th year of the Irish Wetland Bird Survey.

Survey leaders are also keen to know if waterbirds are using a location in an area that is not currently part of its monitoring network so they can add it as a new subsite.

Anyone interested in joining a count team or helping out at other sites is asked to email Niamh at [email protected].

Sensitive habitats such as the Kish Bank off the coast of Dublin and Wicklow have no protection in spite of promised legislation, the Irish Wildlife Trust (IWT) has said.

The NGO has welcomed the announcement by Minister of State for Heritage Malcolm Noonan that a large new special protection area (SPA) for birds is to be designated in the north-west Irish Sea.

“SPAs are designated under existing legislation for the protection of birds and are a form of marine protected area (MPA),” the IWT said in a statement.

“ The announcement brings the coverage of our marine environment falling within designated areas for nature to nearly 10%,” the IWT said.

“The new designation, along with other recent announcements, are vitally important in ensuring that future developments do not result in harm to these sensitive places,” it said.

“ However, in nearly all instances, harmful activities, particularly from fishing, are already underway. If MPAs are to be effective, they must control the fishing,” it said.

The IWT said it was calling on Minister for Agriculture, Food and the Marine Charlie McConalogue, to “accelerate the process of carrying out fisheries assessments in existing MPAs in line with goals to protect and restore biodiversity”.

“creating new MPAs is a critical step in the protection of our seas”

“In particular, this means removing particularly harmful activities such as dredging, bottom trawling or mid-water trawling from these areas,” it said.

“Earlier this year, the European Commission called for the removal of bottom-towed fishing gear from all MPAs and asked that member states, including Ireland, produce a plan for the ending of these practices in existing MPAs by next March,” it said.

IWT campaign officer Pádraic Fogarty said that “creating new MPAs is a critical step in the protection of our seas”.

“They are the foundations for long-term management, but without the management and especially the removal of particularly harmful fishing practices, the designations are meaningless,”he said.

The Government has set a target of protecting 30% of Irish seas by 2030.

An area in the northwest Irish Sea is to be designated as Ireland’s largest ever protected zone for birds.

The proposed new special protection area (SPA) will cover over 230,000 hectares and will increase Ireland’s percentage of marine waters protected under the EU Birds and Habitats directive to over 9 per cent.

That’s according to Minister of State for Heritage and Electoral Reform Malcolm Noonan and National Parks and Wildlife Service (NPWS) director general Niall Ó Donnchú.

Mr Ó Donnchú declared the designation as a “milestone” for the “protection of Ireland’s marine biodiversity”.

The new SPA adjoins twelve existing SPAs already designated along the coast in this area, he says.

The publication of detailed information and maps for the site brings “certainty and clarity to a long-mooted proposal for protections for marine birds in this area”, they state.

“This site, at more than 230,000 hectares, is the largest SPA designation for birds in Ireland’s history,” Mr Noonan said.

“We are working hard as a Government to ensure we have robust protections in place for nature as we work to deliver on our offshore renewable energy objectives. Biodiversity action and climate action must go hand in hand, “he said.

The new north-west Irish Sea SPA extends offshore along the coasts of counties Louth, Meath and Dublin.

It will be of “conservation interest” for these seabirds: Common Scoter; Red-throated Diver; Great Northern Diver; Fulmar; Manx Shearwater; Shag; Cormorant; Little Gull; Kittiwake; Black-headed Gull; Common Gull; Lesser Black-backed Gull, Herring Gull, Great Black-backed Gull, Little Tern, Roseate Tern, Common Tern, Arctic Tern, Puffin, Razorbill and Guillemot

It will adjoin these existing protected areas: Lambay Island SPA; Skerries Island SPA; Ireland's Eye SPA; Howth Head SPA; Rockabill SPA; South Dublin Bay and River Tolka Estuary SPA; Boyne Estuary SPA; River Nanny Estuary and Shore SPA; Rogerstown Estuary SPA; Malahide Estuary SPA; Baldoyle Bay SPA and North Bull Island SPA.

More detailed information about the site, including a map, a species list and a list of the Activities Requiring Consent (ARCs) for the site is available on www.npws.ie/protectedsites.

The NPWS says that in keeping with the Birds and Habitats Regulations 2011, any person with an interest in the proposed site may submit an objection or observation at the following email address: [email protected].

“Objections or observations may only be based on scientific, ornithological grounds,” it says.

Minister of State for Heritage Malcolm Noonan has pledged to find “common ground between fishers, farmers, foresters, NGOs, businesses, scientists and the public” to develop a national restoration plan.

He was commenting after MEPs voted to pass the Nature Restoration Law at the European Parliament.

Welcoming the outcome of the vote, Noonan said he knew that “there are some communities who will be very concerned at today’s news”.

“Let me be clear: nature restoration can only be delivered with the full support of the farming, forestry and fishing communities who own and/or manage our lands and seas. This support is something that, with the help of colleagues across Government, I intend to earn,” he said.

Birdwatch Ireland said a very “weakened law” had been passed, and said it was “really alarming to see that the provisions to restore farmland biodiversity and peatlands were removed completely.

The Irish Wildlife Trust (IWT) said it was delighted that MEPs voted to pass the law, and described it as a “substantial step forward for the European Green Deal”.

“While it could be more ambitious, the law has not been stopped at this critical stage in the biodiversity crisis,” the IWT said.

IWT marine advocacy officer Grace Carr said that amendments involving the Common Fisheries Policy (CFP) are a “step forward for marine restoration and biodiversity”.

She said that there is “still work to be done in negotiations to make the law more ambitious than it currently is”.

The amendment relating to the CFP will ensure member states can put conservation measures in place to protect ecosystems in their waters, the IWT noted, and said this was “particularly welcome”.

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.”
