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.

Howth 17 information

The oldest one-design keelboat racing class in the world is still competing today to its original 1897 design exclusively at Howth Yacht club.

Howth 17 FAQs

The Howth 17 is a type of keelboat. It is a 3-man single-design keelboat designed to race in the waters off Howth and Dublin Bay.

The Howth Seventeen is just 22ft 6ins in hull length.

The Howth 17 class is raced and maintained by the Association members preserving the unique heritage of the boats. Association Members maintain the vibrancy of the Class by racing and cruising together as a class and also encourage new participants to the Class in order to maintain succession. This philosophy is taken account of and explained when the boats are sold.

The boat is the oldest one-design keelboat racing class in the world and it is still racing today to its original design exclusively at Howth Yacht club. It has important historical and heritage value keep alive by a vibrant class of members who race and cruise the boats.

Although 21 boats are in existence, a full fleet rarely sails buy turnouts for the annual championships are regularly in the high teens.

The plans of the Howth 17 were originally drawn by Walter Herbert Boyd in 1897 for Howth Sailing Club. The boat was launched in Ireland in 1898.

They were originally built by John Hilditch at Carrickfergus, County Down. Initially, five boats were constructed by him and sailed the 90-mile passage to Howth in the spring of 1898. The latest Number 21 was built in France in 2017.

The Howth 17s were designed to combat local conditions in Howth that many of the keel-less boats of that era such as the 'Half-Rater' would have found difficult.

The original fleet of five, Rita, Leila, Silver Moon, Aura and Hera, was increased in 1900 with the addition of Pauline, Zaida and Anita. By 1913 the class had increased to fourteen boats. The extra nine were commissioned by Dublin Bay Sailing Club for racing from Kingstown (Dún Laoghaire) - Echo, Sylvia, Mimosa, Deilginis, Rosemary, Gladys, Bobolink, Eileen and Nautilus. Gradually the boats found their way to Howth from various places, including the Solent and by the latter part of the 20th century they were all based there. The class, however, was reduced to 15 due to mishaps and storm damage for a few short years but in May 1988 Isobel and Erica were launched at Howth Yacht Club, the boats having been built in a shed at Howth Castle - the first of the class actually built in Howth.

The basic wooden Howth 17 specification was for a stem and keel of oak and elm, deadwood and frames of oak, planking of yellow pine above the waterline and red pine below, a shelf of pitch pine and a topstrake of teak, larch deck-beams and yellow pine planking and Baltic spruce spars with a keel of lead. Other than the inclusion of teak, the boats were designed to be built of materials which at that time were readily available. However today yellow pine and pitch pine are scarce, their properties of endurance and longevity much appreciated and very much in evidence on the original five boats.

 

It is always a busy 60-race season of regular midweek evening and Saturday afternoon contests plus regattas and the Howth Autumn League.

In 2017, a new Howth 17 Orla, No 21, was built for Ian Malcolm. The construction of Orla began in September 2016 at Skol ar Mor, the boat-building school run by American Mike Newmeyer and his dedicated team of instructor-craftsmen at Mesquer in southern Brittany. In 2018, Storm Emma wrought extensive destruction through the seven Howth Seventeens stored in their much-damaged shed on Howth’s East Pier at the beginning of March 2018, it was feared that several of the boats – which since 1898 have been the very heart of Howth sailing – would be written off. But in the end only one – David O’Connell’s Anita built in 1900 by James Clancy of Dun Laoghaire – was assessed as needing a complete re-build. Anita was rebuilt by Paul Robert and his team at Les Ateliers de l’Enfer in Douarnenez in Brittany in 2019 and Brought home to Howth.

The Howth 17 has a gaff rig.

The total sail area is 305 sq ft (28.3 m2).
