Seaweed is central to a €1.4 million research project exploring opportunities to produce more effective and inexpensive food supplements.

Researchers at University College Dublin (UCD) have been given the four-year award by Science Foundation Ireland for the project, which is entitled “Bio-inspired particle architecture delivery technologies (Bio-PADT)”.

The project involving Prof Kenneth Dawson, Prof Yan Yan, Prof Grace Mulcahy and Prof David Brayden is a partnership between UCD and Marigot Ltd.

Marigot Ltd is described as a pioneer in harvesting and production of seaweed minerals for nutritional value.

The research programme seeks to develop an understanding of marine-derived raw materials, including the company’s product named “Aquamin”, a multi-mineral complex derived from Lithothamnion seaweed species.

The UCD researchers aim to gain a better understanding of the mechanisms in how complex particle materials function.

Dr Siobhán Roche,who is director of science for the economy at Science Foundation Ireland, said the project “highlights the impact of the strategic partnership programme, which aims to build partnerships across academia and industry to address key societal challenges and enhance the competitiveness of our economy”.

Marigot Ltd managing director Michael Ryan said his company is “excited by what the Bio-PADT project can deliver for nutrient delivery and particle interaction with biological barriers and the immune system”.

“We envisage new discoveries which can be groundbreaking for treating micro-nutrient deficiencies and modulating inflammatory processes in human and animal applications,” he said.

Irish renewable energy developer Simply Blue has joined a North Sea consortium working on a commercial scale seaweed farm located within an offshore wind farm.

The “North Sea Farm 1 Project” involves ten hectares of water off the Netherlands coast, and is billed as the world’s first commercial scale operation of its type.

It aims to become operational this autumn when it will be deployed and seeded, with first harvest anticipated during Spring of 2025.

The project is sponsored by Amazon’s “Right Now” climate fund, and aims to help address climate action targets in Europe by “tapping into the vast, unmet potential of seaweed cultivation”.

Seaweed absorbs nitrogen, phosphorus and carbon dioxide and produces oxygen, and has been identified as part of the solution to climate change and ocean acidification.

It produces a valuable biomass with a wide range of uses from pharmaceuticals to animal feed to fertilisers.

Simply Blue Group says it has a keen interest in multiple use of wind farms, and believes that efficient use of sea space is key to working with the oceans on climate change bringing more local communities and supply chains into the transition to a low carbon economy.

“At Simply Blue Group, we want our marine projects to make a tangible difference, which is why we’re delighted to join this consortium,”Simply Blue chief executive and co-founder, said.

Eef Brouwers, project Manager of the North Sea Farm 1 initiative, welcomed Simply Blue’s involvement and said its expertise in aquaculture and offshore wind "will be valuable in the successful execution of seaweed production in an offshore wind farm for the first time”.

“The North Sea Farm 1 project aims to help the seaweed industry in scaling-up within offshore wind farms and Simply Blue Group’s capabilities in both areas make them an ideal partner,” Brouwers said.

North Sea Farmers (NSF) is an independent and not-for-profit sector organisation for the European seaweed industry. It has a member base of over 100 companies, pioneering start-ups, research institutes, NGOs and other stakeholders.

For North Sea Farm 1, NSF will head up a consortium of partner organisations extending across Europe and involved in the entire seaweed production supply chain.

This includes researchers Plymouth Marine Laboratory, Deltares and Silvestrum Climate Associates, seaweed extract manufacturers Algaia and maritime contractors Van Oord.

An aquaculture start-up is celebrating the launch of its first seaweed farm in Connemara, as vegan business magazine Vegconomist reports.

US-based Sea&Believe develops ingredients for food and cosmetics using Palmaria palmata, a red seaweed more commonly known as dillisk or dulse and one that’s recognised for its high nutritional value as well as other health benefits.

The company says it is working with a group of scientists in Galway to develop a sustainable and durable farming process for dillisk in a region notably prone to extreme weather, while also exploring new commercial applications for its natural properties.

Satellite tracking of “pongy” seaweed and algal build up has been developed by University of Galway scientists.

As The Irish Times reports, local authorities can receive complaints of seaweed accumulation, particularly from Dublin residents who may confuse it with sewage discharge.

Scientists studying the patterns of these “golden tides” – named after the colour of ascophyllum nodosum, one of the most common seaweeds on the Irish coastline - have offered their tracking software to the local authorities to help manage the issue.

The researchers from the School of Natural Sciences and Ryan Institute at the University of Galway have been studying these tides in Dublin over a seven-year period.

Led by Dr Liam Morrison and Dr Sara Harro, the University of Galway team monitored seaweed coverage at Dollymount Strand in Dublin Bay between 2016 and 2022 in relation to tides and weather.

Their BioIntertidal Mapper software analyses images from a European Space Agency satellite to help map habitats along the coastline.

It is easier to pump oil from the bottom of the ocean than to farm seaweed, according to French oceans advisor Vincent Doumeizel.

Doumeizel, from Burgundy in France, is a senior advisor on the oceans to the United Nations (UN) Global Compact, a non-binding pact encouraging businesses to adopt sustainable and socially responsible policies.

He is also director of the food programme at the Lloyd’s Register Foundation independent charity and author of “The Seaweed Revolution”, published last year, with illustrations by his daughter Neige.

He says that difficulties in obtaining licenses for seaweed farming are international, and yet the development of seaweed farming is vital to address the needs of the globe’s growing population – and contribute to carbon capture as part of climate breakdown initiatives.

“Seaweed is the healthiest food you can get on the planet”

“I had been working in the food industry for 20 years and began to realise the planet could not feed its growing population, with one billion people starving and an additional 250,000 people to feed daily,” he says.

“For the next 50 years, we are going to have to produce as much food as we ever produced as human beings over the last 10,000 years,” he continues.

“How can we do that? It won’t be possible on land. We have to look to the oceans, which cover 70 per cent of the planet but only contribute to two per cent of our food and calorie supply,” he says.

“Seaweed is the healthiest food you can get on the planet,” Doumeizel said in an interview for Wavelengths.

His book, The Seaweed Revolution, translated by Charlotte Coombe, is published by Legend Press.

A Kerry company says it uses seaweed as an additive to help crops deal with climate change stresses.

Seaweed has long been known for its fertilising qualities on areas of the Atlantic coastline, and research is currently underway here to test its benefits in animal feed in reducing methane outputs

As The Irish Times reports, BioAtlantis in Tralee, Co Kerry has been working on development of natural compounds, extracted from renewable marine and terrestrial resources, to reduce stress in crops, animals and humans by strengthening natural defence systems.

The company is now marketing a product called SuperFifty Prime to help tackle what it calls “abiotic stress”.

“Some 70 per cent of crop losses are due to abiotic stress such as cold, drought, heat, waterlogging, salinity ….. while ten per cent are due to biotic stress such as plant diseases and pathogens,” BioAtlantis research manager Dr Kieran Guinan told the newspaper.

“Even on well-managed farms with full fertiliser and pesticide programmes, crops only reach around 75 per cent of their genetic potential,” he said.

Dr Sujeeth Neerakkal, who heads up plant research at BioAtlantis, says the product is a “highly innovative oxidative stress inhibitor that works by modulating gene expression and inducing a series of stress tolerance mechanisms”.

The company says the technology helps to “prime” crops and plans to tolerate and respond more efficiently to future stresses and potential damage.

Seaweed farming is in its infancy in Ireland, however, a new strategy, BIM Irish Macro-Algal Cultivation Strategy to 2030, published by Bord Iascaigh Mhara (BIM) this week sets out a roadmap for the development of a sustainable and profitable Irish seaweed aquaculture sector.

Seaweed is increasingly being viewed as an important sustainable raw material, containing many active substances for use in different industries including, food production, pharma and agriculture. The commercial cultivation of seaweed has increased significantly in the last two decades. Annual global seaweed output is now in excess of 35 million wet tonnes, 97% of which is cultivated biomass. Most of the farmed seaweed is from Asia (China, Indonesia, Republic of Korea & Philippines).

In referring to the ambitions of the new strategy, Caroline Bocquel, CEO BIM, said: “To ensure a sustainable and economically profitable aquaculture industry in Ireland, the volume of farmed seaweed must increase. This new strategy sets out a roadmap for the seaweed sector to realise its potential. Ireland’s long coastline and clean, cold waters present the ideal conditions to cultivate seaweed, and to sustainably develop this crop that is highly resource efficient, requiring minimal resource input.”

There are currently 25 licenced seaweed farms in Ireland, located along the North West, West and South West coastline Farmed seaweeds are grown on ropes and nets, and are exceptionally fast growing plants.

Michael O’Neill, seaweed farmer, in Allihies, West Cork welcomed the new strategy and spoke of the need to unlock the potential of the seaweed sector in Ireland to meet the growing demand for sustainably produced food.

“The seaweed industry has the highest potential for growth in the Irish aquaculture sector. Ireland has always been a supplier of high-quality seaweeds for various uses, but there have been limitations, to date, on the scalability of the industry.

The advances in cultivation technology and processing, leaves Ireland extremely well positioned to become a major player in the international seaweed industry, with the demand for seaweed biomass and seaweed-based products outstripping supply for the foreseeable future.

Pure Ocean Algae welcomes the new strategy and looks forward to playing its part in the implementation of the findings of this review.”

Royal National Lifeboat Institute (RNLI) in Ireland Information

The Royal National Lifeboat Institution (RNLI) is a charity to save lives at sea in the waters of UK and Ireland. Funded principally by legacies and donations, the RNLI operates a fleet of lifeboats, crewed by volunteers, based at a range of coastal and inland waters stations. Working closely with UK and Ireland Coastguards, RNLI crews are available to launch at short notice to assist people and vessels in difficulties.

RNLI was founded in 1824 and is based in Poole, Dorset. The organisation raised €210m in funds in 2019, spending €200m on lifesaving activities and water safety education. RNLI also provides a beach lifeguard service in the UK and has recently developed an International drowning prevention strategy, partnering with other organisations and governments to make drowning prevention a global priority.

Irish Lifeboat Stations

There are 46 lifeboat stations on the island of Ireland, with an operational base in Swords, Co Dublin. Irish RNLI crews are tasked through a paging system instigated by the Irish Coast Guard which can task a range of rescue resources depending on the nature of the emergency.

Famous Irish Lifeboat Rescues

Irish Lifeboats have participated in many rescues, perhaps the most famous of which was the rescue of the crew of the Daunt Rock lightship off Cork Harbour by the Ballycotton lifeboat in 1936. Spending almost 50 hours at sea, the lifeboat stood by the drifting lightship until the proximity to the Daunt Rock forced the coxswain to get alongside and successfully rescue the lightship's crew.

32 Irish lifeboat crew have been lost in rescue missions, including the 15 crew of the Kingstown (now Dun Laoghaire) lifeboat which capsized while attempting to rescue the crew of the SS Palme on Christmas Eve 1895.


While the number of callouts to lifeboat stations varies from year to year, Howth Lifeboat station has aggregated more 'shouts' in recent years than other stations, averaging just over 60 a year.

Stations with an offshore lifeboat have a full-time mechanic, while some have a full-time coxswain. However, most lifeboat crews are volunteers.

In 2019, 8,941 lifeboat launches saved 342 lives across the RNLI fleet.

The Irish fleet is a mixture of inshore and all-weather (offshore) craft. The offshore lifeboats, which range from 17m to 12m in length are either moored afloat, launched down a slipway or are towed into the sea on a trailer and launched. The inshore boats are either rigid or non-rigid inflatables.

The Irish Coast Guard in the Republic of Ireland or the UK Coastguard in Northern Ireland task lifeboats when an emergency call is received, through any of the recognised systems. These include 999/112 phone calls, Mayday/PanPan calls on VHF, a signal from an emergency position indicating radio beacon (EPIRB) or distress signals.

The Irish Coast Guard is the government agency responsible for the response to, and co-ordination of, maritime accidents which require search and rescue operations. To carry out their task the Coast Guard calls on their own resources – Coast Guard units manned by volunteers and contracted helicopters, as well as "declared resources" - RNLI lifeboats and crews. While lifeboats conduct the operation, the coordination is provided by the Coast Guard.

A lifeboat coxswain (pronounced cox'n) is the skipper or master of the lifeboat.

RNLI Lifeboat crews are required to follow a particular development plan that covers a pre-agreed range of skills necessary to complete particular tasks. These skills and tasks form part of the competence-based training that is delivered both locally and at the RNLI's Lifeboat College in Poole, Dorset


While the RNLI is dependent on donations and legacies for funding, they also need volunteer crew and fund-raisers.
