With the Lusitania expedition in the news, Saturday's Irish Times presents a guide to some of Ireland's most interesting diving sites for all levels of experience.
Though Ireland can boast an abundance of shipwreck sites, a number of them are off-limits to anyone but the hardiest expert explorers, while others require a licence from the Department of Hertiage.
But open dives are still plenty, such as the wreck of UC-42 off Roches Point in Cork, which happens to lie in a popular diving range, and the Empire Hertiage, which lies 30km off the coast of Malin Head and is regarded as one of Ireland's best wreck dives.
Among the licenced dives, the HMS Vanguard - which was tragically sunk 19km east of Bray by its sister ship Iron Duke in 1875 - is a top contender, with the summer months providing astounding visibility of the ships 9in guns.

Cork gardaí are investigating the looting of items from a First World War U-boat recently discovered off Roches Point.
The Irish Times reports that the submarine also appears to have been damaged by the illegal salvagers.
A spokesperson for the underwater archaeology unit of the Department of Arts, Heritage and the Gaeltacht confirmed that reports had come in from divers regarding disturbance of the wreck site - noting attempts to remove parts of the structure, and details of human remains.
Divers with the unit were expected to assess the site as soon as weather permits.
Items believed to have been taken include sailor's attire belonging to the crew of the 49-metre German vessel UC-42, which sank in 1917. The German embassy has indicated its "legitimate interest" in the preservation of the wreck.

Scuba Divers have found a fully intact World War I U-Boat on the seabed just outside Cork harbour, some 93 years after it sank writes Timmy Carey.

During the First World War the menace provided by German U-Boats would prove deadly to the Allies and were responsible for sinking millions of tons of shipping; indeed German U-Boats almost changed the course of the war. Most allied ships sunk by U-boats were sunk by either torpedo, deck gunfire or explosives placed aboard the ship by U-boat crew. A smaller number of ships were also sunk by mine laying U-boats; one of these being UC42. On the 10th of September of 1917 UC42 was laying her deadly cargo of mines at the entrance to Cork harbour when a terrific explosion occurred which resulted in a grim death for all 27 German Submariners aboard.

As the submarine sank to the seabed the German submariners were trapped inside UC42, which would soon become their metal tomb.

On November  2nd of that year, hardhat divers from the Haulbowline dockyard dived the area and positively identified the U-boat as UC42, noting the stern damage to the submarine and the presence of the bodies of some of the German submariners. During 1918 the submarine was dived by Haulbowline and American divers in an effort to disarm all the mines and torpedoes still aboard, with USS Melville taking three of the mines. It was widely believed that in July 1919 divers using explosives from HMS Vernon torpedo school had destroyed the submarine with the remains being dispersed on the seabed by wire sweeps.

With the advent of scuba diving many divers have since searched for the scattered remains of UC42 around Cork harbour with no luck until a recent dive by two local divers Ian Kelleher and Niall O Regan descended a shot line to see the menacing sight of the hull of a German U-boat emerge from the shadows. Both divers were very surprised and ecstatic to find a fully intact World War I U-Boat in 27 meters of water just outside Cork harbour in good condition with little obvious explosive damage from the British naval dive team.

A local dive team of five divers had spent the previous 12 months carrying out a careful methodical search of the greater harbour area determined to find the remains of the submarine; their hard labours finally paying dividends when Niall and Ian identified the presence of the submarine. The dive team consisted of Ian Kelleher, Niall O Regan, Philip Johnston,  Eoin Mc Garry and Timmy Carey.

Over the past few weeks the divers have carefully and methodically videoed and photographed the Submarine and taken various measurements to record the wrecks' condition. Over a number of dives the dive team carefully cleaned the growth from the propeller and after some methodical cleaning found the U-Boats number UC42 stamped into it; positively identifying the submarine.

As the submarine is a war grave and contains the remains of so many young German submariners the dive team also laid a plaque of remembrance, which was erected near the submarines propellers; to act as a memorial to the German submariners forever entombed in UC42. The plaque was kindly donated to the dive team by John O' Mahony of Complete Signs.

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.”
