A leading specialist in the ecology of Irish kelp forests along the Atlantic coastline has been given an award by the Irish Research Council (IRC).

NUI Galway marine ecologist Dr Kathryn Schoenrock has been given Early Career Researcher of the Year award.

Dr Schoenrock is a post-doctoral researcher who has led an intensive monitoring effort in kelp forests over the past three years, which is the first of its kind.

The IRC says her “ground-breaking work in this field has made her the authoritative voice on Irish kelp forest ecology, and the productivity and biodiversity of these systems in nearshore waters”.

Dr Schoenrock reported the first discovery of golden kelp in Irish waters last year. The small population was discovered in Scots Port cove on the north-west facing Belmullet coastline in Co Mayo.

Scots Port is located 1,040km from the nearest golden kelp population in Britain, and 1,630km away from the nearest population in France.

The dominant kelp species found in Irish waters is Cuvie (Laminaria Hyperborea), and five main types of kelp provide important habitats for marine life.

Kelp forest habitats are recognised as an important primary resource for terrestrial and marine organisms.

“ Recently they have been highlighted as an important blue carbon repository that may buffer climate change impacts to marine habitats by sequestering the increasing concentrations of carbon dioxide in our atmosphere,”the IRC notes.

There has been recent industry interest in, and environmental concern about, harvesting the native subtidal kelp, Laminaria Hyperborea.

Dr Schoenrock says she hopes her work will “inform academic studies, conservation planning, and industry ventures in the future”.

She says her work has led to international collaborations, laying the foundation for current research funding with the EPA, and she contributes data from Irish coastlines to national, European and international kelp forest monitoring networks.

She specialises in studying species response to climate change, ecophysiology of primary producers (seaweeds), chemical and marine ecology, and population and environmental genetics of marine seaweeds.

Her use of scientific diving in my research has supported development of a scientific diving dive-control board at NUIG, where she is dive officer, and taught the first Irish scientific (not technical) diving course there in spring-summer 2020.

Kelp found on the coast of Ireland may have survived some 16,000 years since the last ice age, scientists have discovered — and it could be crucial to understanding how marine plants deal with climate change long-term.

According to AOL News, the team from universities in Scotland, France and Portugal studied the genetic composition of a type of kelp known as oarweed from 14 sites in the North Atlantic and found three distinct clusters — one along North America’s Eastern Seaboard, one off Ireland and Scotland, and another around Brittany.

“As the ice sheets retreated from northern European shorelines at the end of the most recent ice age, oarweed distribution followed and recolonised the higher latitudes of the Atlantic,” said marine ecologist Dr Andrew Watt from Heriot-Watt University.

As a result, the oarweed found in Ireland and Scotland today, many millennia later, is “more closely related to populations in the high Arctic than to the Brittany cluster”.

Despite their unique characteristics, it’s hoped the genetic similarity between the three clusters can help marine science experts learn how plant life can bridge such extremes of climate change.

Citizen science pinpointed the first samples of a rare kelp in Irish waters, and now NUI Galway researchers are hoping that sea swimmers, divers and kayakers may help to find more writes Lorna Siggins

Samples of golden kelp (Laminaria ochroleuca), which is normally found in France, Spain and Britain, were identified for the first time almost a year ago in north Mayo.

The small population was discovered in Scots Port cove on the north-west facing Belmullet coastline, and recognised by Dr Kathryn Schoenrock of NUI Galway’s (NUIG) Ryan Institute.

“Golden kelp, which harbours less biodiversity, is a really important species in Spain and Portugal,” Dr Schoenrock explained.

“We would have expected to find the first samples here on Ireland’s south-east coast, given the proximity to Britain, France and Spain,” she says.

Scots Port is located 1,040 kilometres away from the nearest golden kelp population in Britain, and 1,630 kilometres away from the nearest population in France.

Genetic analyses would suggest that the Co Mayo population is more diverse than the British, resembling the richness described for populations in the Iberian peninsula, Dr Schoenrock said.

“The fact that it was found in a small enclosed cove in north Mayo may be a result of a Portuguese or Spanish vessel sheltering nearby,” she says.

“However, it can drift long distances and it could be more prevalent than we know.”

The samples found by citizen science participants in a Searsearch Ireland and Porcupine survey trip were collected by Dr Stacy A Krueger-Hadfield for genetic analysis at the University of Alabama at Birmingham in North America.

The discovery was the subject of a study which had recently been published in the scientific journal, Marine Biodiversity Records.

Dr Schoenrock said that citizen science initiatives like Seasearch Ireland and Coastwatch are an “excellent way to involve local communities that have a vested interest in the health of these ecosystems”.

“In conjunction with existing research bodies like the Environmental Protection Agency (EPA), National Parks and Wildlife Services, and the Marine Institute, we need more programmes that can sustain long term ecological research of shallow marine systems over many years,” she said.

Seasearch Ireland national co-ordinator Tony O’Callaghan said that its participants had collected over 50,000 records of over 1,000 species.

He said the data set is “the best continuous record collected since the last major state-funded study of Ireland’s inshore marine environment, the Biomar survey, which was in the 90s.”

This project is funded under the EPA Research Programme 2014-2020.

Given that golden kelp has much lower biodiversity than native kelp forests, it is more suitable kelp to harvest, Dr Schoenrock noted.

“It can grow to a larger size and it doesn’t dominate habitats yet in Ireland,” she said.

State approval in November 2017 of a license to harvest native kelp by mechanical means in Bantry Bay has aroused opposition on environmental grounds in West Cork and resulted in ongoing litigation.

The Round Britain & Ireland Race

The 2022 Sevenstar Round Britain and Ireland Race will feature a wide variety of yachts racing under the IRC rating rule as well as one design and open classes, such as IMOCA, Class40 and Multihulls. The majority of the fleet will race fully crewed, but with the popularity of the Two-Handed class in recent years, the race is expected to have a record entry.

The Sevenstar Round Britain and Ireland Race starts on Sunday 7th August 2022 from Cowes, Isle of Wight, UK.

The 2022 Sevenstar Round Britain and Ireland Race is organised by The Royal Ocean Racing Club in association with The Royal Yacht Squadron.

It is run every four years. There have been nine editions of the Round Britain and Ireland Race which started in 1976 Sevenstar has sponsored the race four times - 2006, 2010, 2014, 2018 and has committed to a longterm partnership with the RORC

The 2022 Sevenstar Round Britain and Ireland Race is a fully crewed non-stop race covering 1,805 nautical miles and is open to IRC, IRC Two Handed, IMOCA 60s, Class40s, Volvo 65s and Multihulls that will race around Britain and Ireland, starting from the Royal Yacht Squadron line in Cowes on the Isle of Wight starting after Cowes Week on Sunday 7 August 2022

The last edition of the race in 2018 attracted 28 teams with crews from 18 nations. Giles Redpath's British Lombard 46 saw over victory and Phil Sharp's Class40 Imerys Clean Energy established a new world record for 40ft and under, completing the course in 8 days 4 hrs 14 mins 49 secs.

The 1,805nm course will take competitors around some of the busiest and most tactically challenging sailing waters in the world. It attracts a diverse range of yachts and crew, most of which are enticed by the challenge it offers as well as the diversity and beauty of the route around Britain and Ireland with spectacular scenery and wildlife.

Most sailors agree that this race is one of the toughest tests as it is nearly as long as an Atlantic crossing, but the changes of direction at headlands will mean constant breaks in the watch system for sail changes and sail trim
