Ahead of its broadcast this weekend, Newstalk previews A Sea of Sound, a new radio documentary that explores the impact of noise pollution on marine wildlife.

Marine mammals such as dolphins and whales effectively ‘see’ through sound in the water. “So to understand the life they lead, as the Irish Whale and Dolphin Group’s Simon Berrow says, we need to “think acoustically”.

Producer John Higgins spoke to Berrow and other environmental stakeholders for the documentary, which also features some of the remarkable sounds of whales and dolphins communicating beneath the waves — and explores the sounds that threaten them, from seismic surveys to military sonar and more.

A Sea of Sound will be broadcast on Newstalk this Sunday morning 27 March at 7am, with a repeat on Saturday 2 April at 9pm. It will also be available as a podcast.

When cruiseships dock in Cobh they have been warned to keep quiet by the Port of Cork.

The busy port, writes Echolive, which sees up to 100 cruise liners docking throughout the year in the tourist town, has issued a statement regarding noise levels at certain times in an effort to maintain a good relationship with local residents.

In a notice, issued by Captain Paul O’Regan, who is Harbour Master and Chief Operations Officer for the Port of Cork, cruise liner captains were asked to reduce noise pollution in the area.

The notice from Captain O’Regan said that due to the topography of Cobh Cruise Berth, the sound from passenger announcements, music played on external decks and alarm sirens were amplified and this can be an issue for the surrounding residential properties.

Over 300 scientists are meeting in Dublin this week discussing the effects of noise on aquatic life. A public talk on Noise and its impact in the Ocean will be given tonight (Tuesday 12th July) 8 – 9:30pm at the O’Callaghan Alexander Hotel, Fenian Street, off Merrion Square in Dublin.

When people think of pollution they conjure up images of sewage spilling into the oceans, massive oil spills, floating rubbish and maybe even toxic chemicals. Noise pollution, however, is easily left out of such thoughts. Nevertheless, pollution from noise is likely as dangerous to many marine animals as any other type of pollution. 

Ocean noise pollutionAnthony Hawkins (Aquatic Noise Trust UK) and Robert Gisnier (International Association of Geophsyical Contractors US) met with 300 scientists attending the 4th International Conference on the Effects of Noise on Aquatic Life. A public talk on Noise in the Ocean and its impact will be given tonight at 8 – 9:30pm at the O’Callaghan Alexander Hotel, Fenian Street, off Merrion Square in Dublin

#MARINE SCIENCE - Apart from some of the world's largest concentrations of wave energy, the waters of Galway Bay and the west coast of Ireland are now providing something potentially even more valuable - information.

That's according to IBM's Harry Kolar writing for the blog A Smarter Planet, as he discusses the start of his company's new underwater data collection project developed in association with the Sustainable Energy Authority of Ireland (SEAI) and the Marine Institute.

As previously reported on Afloat.ie, the system comprises an array of noise sensing equipment such as hydrophones deployed in Galway Bay to monitor the noise levels produced by wave energy conversion devices in real time.

This array is attached to a large monitoring buoy about 2km from the southern shore, and constantly transmits the data it records to a receiving system on land.

The scheme, which was finally switched on last month, is an offshoot of the SmartBay initiative for developing and testing new marine technology to foster future commercial development in the fast-growing marine science sector. The 'Twitter buoy' deployed for the Volvo Ocean Race finale recently is another of the project's schemes.

"Initially, the system will capture and analyse the ambient noise of the ocean to establish a baseline of acoustics including natural and anthropogenic (man-made) sound sources including vessel traffic," writes Kolar.

"But the ultimate goal is to capture and analyse the sounds and vibrations of hulking wave energy conversion machines that have begun bobbing along off the coast and help determine what, if any impact the sound waves from those devices could have on marine life – but especially highly sensitive dolphin, porpoise, and whale populations."

#POWER FROM THE SEA - The Sustainable Energy Authority of Ireland (SEAI) is teaming with IBM in a new project to assess the noise levels of wave energy devices off the Irish coast.
The scheme will see an array of noise sensing equipment such as hydrophones deployed in Galway Bay to monitor the noise levels of wave energy conversion devices in real time, as well as map patterns of marine life in the area.
According to AOL Energy, noise pollution at sea is a chief concern, having a disturbing effect on fish migrations among other marine ecosystems.
The west of Ireland will prove an important case study in this regard, as it hosts one of the world's largest wave energy infrastructures.
"Underwater noise is a global environmental issue that has to be addressed if we are going to take advantage of the huge potential of ocean energy," said EU Commissioner for Research, Innovation and Science, Maire Geoghegan-Quinn.

Dublin Bay 21s

An exciting new project to breathe life into six defunct 120-year-old Irish yachts that happen to be the oldest intact one-design keelboat class in the world has captured the imagination of sailors at Ireland's biggest sailing centre. The birthplace of the original Dublin Bay 21 class is getting ready to welcome home the six restored craft after 40 years thanks to an ambitious boat building project was completed on the Shannon Estuary that saved them from completely rotting away.

Dublin Bay 21 FAQs

The Dublin Bay 21 is a vintage one-design wooden yacht designed for sailing in Dublin Bay.

Seven were built between 1903 and 1906.

As of 2020, the yachts are 117 years old.

Alfred Mylne designed the seven yachts.

The total voting population in the Republic's inhabited islands is just over 2,600 people, according to the Department of Housing.

Dublin Bay Sailing Club (DBSC) commissioned the boat to encourage inexpensive one-design racing to recognise the success of the Water Wag one-design dinghy of 1887 and the Colleen keelboat class of 1897.

Estelle built by Hollwey, 1903; Garavogue built by Kelly, 1903; Innisfallen built by Hollwey, 1903.; Maureen built by Hollwey, 1903.; Oola built by Kelly, 1905; Naneen built by Clancy, 1905.

Overall length- 32'-6', Beam- 7'-6", Keel lead- 2 tons Sail area - 600sq.ft

The first race took place on 19 June 1903 in Dublin Bay.

They may be the oldest intact class of racing keelboat yacht in the world. Sailing together in a fleet, they are one of the loveliest sights to be seen on any sailing waters in the world, according to many Dublin Bay aficionados.

In 1964, some of the owners thought that the boats were outdated, and needed a new breath of fresh air. After extensive discussions between all the owners, the gaff rig and timber mast was abandoned in favour of a more fashionable Bermudan rig with an aluminium mast. Unfortunately, this rig put previously unseen loads on the hulls, resulting in some permanent damage.

The fleet was taken out of the water in 1986 after Hurricane Charlie ruined active Dublin Bay 21 fleet racing in August of that year. Two 21s sank in the storm, suffering the same fate as their sister ship Estelle four years earlier. The class then became defunct. In 1988, master shipwright Jack Tyrrell of Arklow inspected the fleet and considered the state of the hulls as vulnerable, describing them as 'still restorable even if some would need a virtual rebuild'. The fleet then lay rotting in a farmyard in Arklow until 2019 and the pioneering project of Dun Laoghaire sailors Fionan De Barra and Hal Sisk who decided to bring them back to their former glory.

Hurricane Charlie finally ruined active Dublin Bay 21 fleet racing in August 1986. Two 21s sank in the storm, suffering the same fate as a sister ship four years earlier; Estelle sank twice, once on her moorings and once in a near-tragic downwind capsize. Despite their collective salvage from the sea bed, the class decided the ancient boats should not be allowed suffer anymore. To avoid further deterioration and risk to the rare craft all seven 21s were put into storage in 1989 under the direction of the naval architect Jack Tyrrell at his yard in Arklow.

While two of the fleet, Garavogue and Geraldine sailed to their current home, the other five, in various states of disrepair, were carried the 50-odd miles to Arklow by road.

To revive the legendary Dublin Bay 21 class, the famous Mylne design of 1902-03. Hal Sisk and Fionan de Barra are developing ideas to retain the class's spirit while making the boats more appropriate to today's needs in Dun Laoghaire harbour, with its many other rival sailing attractions. The Dublin Bay 21-foot class's fate represents far more than the loss of a single class; it is bad news for the Bay's yachting heritage at large. Although Dún Laoghaire turned a blind eye to the plight of the oldest intact one-design keelboat fleet in the world for 30 years or more they are now fully restored.

The Dublin Bay 21 Restoration team includes Steve Morris, James Madigan, Hal Sisk, Fionan de Barra, Fintan Ryan and Dan Mill.

Retaining the pure Mylne-designed hull was essential, but the project has new laminated cold-moulded hulls which are being built inverted but will, when finished and upright, be fitted on the original ballast keels, thereby maintaining the boat’s continuity of existence, the presence of the true spirit of the ship.

It will be a gunter-rigged sloop. It was decided a simpler yet clearly vintage rig was needed for the time-constrained sailors of the 21st Century. So, far from bringing the original and almost-mythical gaff cutter rig with jackyard topsail back to life above a traditionally-constructed hull, the project is content to have an attractive gunter-rigged sloop – “American gaff” some would call it.

The first DB 21 to get the treatment was Naneen, originally built in 1905 by Clancy of Dun Laoghaire for T. Cosby Burrowes, a serial boat owner from Cavan.

On Dublin Bay. Dublin Bay Sailing Club granted a racing start for 2020 Tuesday evening racing starting in 2020, but it was deferred due to COVID-19.
Initially, two Dublin Bay 21s will race then three as the boat building project based in Kilrush on the Shannon Estuary completes the six-boat project.
The restored boats will be welcomed back to the Bay in a special DBSC gun salute from committee boat Mac Lir at the start of the season.
In a recollection for Afloat, well known Dun Laoghaire one-design sailor Roger Bannon said: "They were complete bitches of boats to sail, over-canvassed and fundamentally badly balanced. Their construction and design was also seriously flawed which meant that they constantly leaked and required endless expensive maintenance. They suffered from unbelievable lee helm which led to regular swamping's and indeed several sinkings.
