Marine Notice: Survey Investigation Works for Atlantic Marine Energy Test Site
The Department of Transport has been advised by Sustainable Energy Authority Ireland (SEAI) that the Marine Institute will undertake site investigation survey works at the Atlantic Marine Energy Test Site (AMETS) in Co Mayo.
The survey is expected to be completed over a 10-day period from Sunday 17 September, subject to weather and operational constraints.
Geophysical and geotechnical survey work and benthic sampling will be carried out at Test Area A, 16km from Belderra Strand, and Test Area B, 6km from Belderra Strand on the Erris Peninsula. Benthic sampling will be carried out along the proposed cable corridor at AMETS.
The survey vessel RV Celtic Explorer (callsign EIGB) will carry out the site investigation works. Throughout operations, the vessel will be displaying appropriate lights and shapes, and will also be restricted in its ability to manoeuvre.
Other vessels operating in the AMETS area are requested to give the survey vessel a wide berth during survey operations. Mariners are also advised to keep continuous watch on VHF Channel 16 when navigating the survey area at AMETS.
Coordinates and a map of the survey areas as well as contact details can be found in Marine Notice No 55 of 2023, attached below.
Surface ocean carbon dioxide observations from Irish waters collected by the Marine Institute’s RV Celtic Explorer have been published in the 2023 version of the Surface Ocean CO2 Atlas (SOCAT).
With over 42 million surface ocean CO2 measurements from across the globe, SOCAT is a key dataset for quantifying the evolving ocean uptake and sink for CO2.
This data provides scientists, climate researchers and international policy makers with essential information on ocean carbon dioxide measurements. And such observations are essential to understand current and project future climate change as well as for monitoring changes in ocean chemistry and predicting the impacts of these changes.
Atmospheric carbon dioxide concentrations continue to rise rapidly and currently are at about 420 parts per million (ppm), up from 280ppm in preindustrial times.
The current atmospheric level would be significantly higher, and climate change even more pronounced, but for our global ocean absorbing about a quarter of CO2 emissions from human activities each year.
There is, however, a cost: Absorbing additional CO2 increases the acidity of seawater. This process is known as ocean acidification, and it may have dramatic consequences for marine life, as detailed in a recent assessment by OSPAR.
If sea water is too acidic, it can make it difficult for marine organisms such as coral, oysters and mussels to form shells and skeletons. The impacts of ocean acidification and warming could also extend up the food chain, affecting fisheries and aquaculture, threatening food security for millions of people.
Evin McGovern at the Marine Institute, who was co-convenor of the international expert group that produced the OSPAR Ocean Acidification assessment said: “High-quality measurements of surface ocean carbon dioxide are needed for a better understanding of the impact of ocean-atmosphere interactions on climate. The Marine Institute is contributing to global science, providing advanced scientific knowledge which will help inform policy and our response to a changing ocean.”
Ocean and atmospheric CO2 measurements have been collected on the RV Celtic Explorer since 2017. This year Ireland joined the Integrated Carbon Observing Station (ICOS), a European Infrastructure network supporting standardised high-precision carbon flux measurements between atmosphere, land and the ocean, and the RV Celtic Explorer was adopted as an ICOS Ocean “station”.
In Ireland, marine CO2 measurements are also collected at fixed stations and additional CO2 observing capacity will be available on the new national research vessel, the RV Tom Crean, extending the coverage.
Marine Notice: Site Investigation Surveys at Proposed Atlantic Marine Energy Test Site
MERC Environmental Consultants Ltd and the Marine Institute are undertaking site investigation survey works at the Atlantic Marine Energy Test Site in Co Mayo.
The surveys are expected to be completed over a three-day period during the nearest available weather window which opened last Thursday 2 March, subject to weather and operational constraints.
Survey works include a benthic survey as well as geotechnical and geophysical surveys.
The survey campaign will be undertaken within the proposed Atlantic Marine Energy Test Site, consisting of two separate areas. Test Site A is 16km from Belderra Strand, and Test Site B is 6km from Belderra Strand on the Erris Peninsula.
The benthic survey work will be conducted by the Dúlra na Mara (callsign EIFS6) a shallow draft survey vessel. Meanwhile the survey vessel RV Celtic Explorer (callsign EIGB) will carry out geophysical and geotechnical site investigation works offshore at Test Site A and Test Site B and along the proposed cable corridor.
During operations the work vessels will be restricted in their ability to manoeuvre. All other vessels are requested to leave a wide berth during the deployment operations.
The survey operations will be conducted during daylight hours only. Mariners are advised to keep continuous watch on VHF Channel 16 when navigating the survey area at the Atlantic Marine Energy Test Site.

Marine Institute’s Fisheries Research Features in Euronews Documentary
Fisheries research undertaken by Marine Institute scientists features in a new short documentary from Europe's leading international news channel.
Produced by Euronews, ‘Where’s the catch? The fishery surveys keeping our seas sustainable’ follows the RV Celtic Explorer during the annual Irish Groundfish Survey (IGFS), which most recently took place from October to December 2021.
This six-week fisheries survey in Ireland’s Atlantic shelf takes place each year, with the survey passing through 170 points on the nautical chart.
The IGFS assesses commercially exploited fish stocks, such as haddock and whiting. The survey provides an index of the share of young fish in the stock, which in turn gives an indication of its spawning success.
In the video, David Stokes of the Marine Institute, and chief scientist on the IGFS, explains the sampling processes and the survey’s importance, while scientists Jennifer Doyle and Sinead O’Brien discuss what data is collected in the research vessel’s laboratory.
This Irish survey is one of many conducted in a coordinated way along the northern and western coasts of the European continent. The data collected from all surveys is compiled and analysed by the International Council for the Exploration of the Seas (ICES).
Dr Ciaran Kelly, director of fisheries, ecosystems and advisory services at the Marine Institute, said: “We are delighted for our work to be featured in this Euronews documentary, as Marine Institute scientists play a key role in carrying out assessments and developing the scientific evidence and advice at ICES.
“The important scientific work undertaken by our scientists is essential for supporting a sustainable ocean economy, as well as protecting and managing our marine ecosystems.”
The video is part of the monthly ‘Ocean’ series produced by Euronews and the European Commission, which is broadcast in nine languages and available in 160 countries.
