How we monitor, analyse and understand the changes in our ocean climate is vital in providing the basis for effective policies to address a range of issues and challenges — such as changing ecosystems, food security, rising sea levels and extreme weather events.

This ocean climate work is the focus of this week’s Oceans of Learning series, with resources from the Marine Institute and Met Éireann, the Irish meteorological service.

“Our ocean is fundamental to life on earth and affects so many facets of our everyday activities,” says Marine Institute chief executive Dr Paul Connolly. “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 the 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.

During the 2019 survey, the RV Celtic Explorer deployed a replacement M6 weather buoy as part of the Irish Marine Data Buoy Observation Network (IMDBON).

The 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 that 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.”

Oceans of Learning offers downloadable resources such as videos, fact sheets and interactive activities on Ireland’s climate monitoring projects. To access the resources for this week’s series, visit A Changing Ocean Climate.

Coastal Notes Coastal Notes covers a broad spectrum of stories, events and developments in which some can be quirky and local in nature, while other stories are of national importance and are on-going, but whatever they are about, they need to be told.

Stories can be diverse and they can be influential, albeit some are more subtle than others in nature, while other events can be immediately felt. No more so felt, is firstly to those living along the coastal rim and rural isolated communities. Here the impact poses is increased to those directly linked with the sea, where daily lives are made from earning an income ashore and within coastal waters.

The topics in Coastal Notes can also be about the rare finding of sea-life creatures, a historic shipwreck lost to the passage of time and which has yet many a secret to tell. A trawler's net caught hauling more than fish but cannon balls dating to the Napoleonic era.

Also focusing the attention of Coastal Notes, are the maritime museums which are of national importance to maintaining access and knowledge of historical exhibits for future generations.

Equally to keep an eye on the present day, with activities of existing and planned projects in the pipeline from the wind and wave renewables sector and those of the energy exploration industry.

In addition Coastal Notes has many more angles to cover, be it the weekend boat leisure user taking a sedate cruise off a long straight beach on the coast beach and making a friend with a feathered companion along the way.

In complete contrast is to those who harvest the sea, using small boats based in harbours where infrastructure and safety poses an issue, before they set off to ply their trade at the foot of our highest sea cliffs along the rugged wild western seaboard.

It's all there, as Coastal Notes tells the stories that are arguably as varied to the environment from which they came from and indeed which shape people's interaction with the surrounding environment that is the natural world and our relationship with the sea.
