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.

Marine Protected Areas (MPAs) - FAQS

Marine protected areas (MPAs) are geographically defined maritime areas where human activities are managed to protect important natural or cultural resources. In addition to conserving marine species and habitats, MPAs can support maritime economic activity and reduce the effects of climate change and ocean acidification.

MPAs can be found across a range of marine habitats, from the open ocean to coastal areas, intertidal zones, bays and estuaries. Marine protected areas are defined areas where human activities are managed to protect important natural or cultural resources.

The world's first MPA is said to have been the Fort Jefferson National Monument in Florida, North America, which covered 18,850 hectares of sea and 35 hectares of coastal land. This location was designated in 1935, but the main drive for MPAs came much later. The current global movement can be traced to the first World Congress on National Parks in 1962, and initiation in 1976 of a process to deliver exclusive rights to sovereign states over waters up to 200 nautical miles out then began to provide new focus

The Rio ‘Earth Summit’ on climate change in 1992 saw a global MPA area target of 10% by the 2010 deadline. When this was not met, an “Aichi target 11” was set requiring 10% coverage by 2020. There has been repeated efforts since then to tighten up MPA requirements.

Marae Moana is a multiple-use marine protected area created on July 13th 2017 by the government of the Cook islands in the south Pacific, north- east of New Zealand. The area extends across over 1.9 million square kilometres. However, In September 2019, Jacqueline Evans, a prominent marine biologist and Goldman environmental award winner who was openly critical of the government's plans for seabed mining, was replaced as director of the park by the Cook Islands prime minister’s office. The move attracted local media criticism, as Evans was responsible for developing the Marae Moana policy and the Marae Moana Act, She had worked on raising funding for the park, expanding policy and regulations and developing a plan that designates permitted areas for industrial activities.

Criteria for identifying and selecting MPAs depends on the overall objective or direction of the programme identified by the coastal state. For example, if the objective is to safeguard ecological habitats, the criteria will emphasise habitat diversity and the unique nature of the particular area.

Permanence of MPAs can vary internationally. Some are established under legislative action or under a different regulatory mechanism to exist permanently into the future. Others are intended to last only a few months or years.

Yes, Ireland has MPA cover in about 2.13 per cent of our waters. Although much of Ireland’s marine environment is regarded as in “generally good condition”, according to an expert group report for Government published in January 2021, it says that biodiversity loss and ecosystem degradation are of “wide concern due to increasing pressures such as overexploitation, habitat loss, pollution, and climate change”.

The Government has set a target of 30 per cent MPA coverage by 2030, and moves are already being made in that direction. However, environmentalists are dubious, pointing out that a previous target of ten per cent by 2020 was not met.

Conservation and sustainable management of the marine environment has been mandated by a number of international agreements and legal obligations, as an expert group report to government has pointed out. There are specific requirements for area-based protection in the EU Marine Strategy Framework Directive (MSFD), the OSPAR Convention, the UN Convention on Biological Diversity and the UN Sustainable Development Goals. 

Yes, the Marine Strategy Framework directive (2008/56/EC) required member states to put measures in place to achieve or maintain good environmental status in their waters by 2020. Under the directive a coherent and representative network of MPAs had to be created by 2016.

Ireland was about halfway up the EU table in designating protected areas under existing habitats and bird directives in a comparison published by the European Commission in 2009. However, the Fair Seas campaign, an environmental coalition formed in 2022, points out that Ireland is “lagging behind “ even our closest neighbours, such as Scotland which has 37 per cent. The Fair Seas campaign wants at least 10 per cent of Irish waters to be designated as “fully protected” by 2025, and “at least” 30 per cent by 2030.

Nearly a quarter of Britain’s territorial waters are covered by MPAs, set up to protect vital ecosystems and species. However, a conservation NGO, Oceana, said that analysis of fishing vessel tracking data published in The Guardian in October 2020 found that more than 97% of British MPAs created to safeguard ocean habitats, are being dredged and bottom trawled. 

There’s the rub. Currently, there is no definition of an MPA in Irish law, and environment protections under the Wildlife Acts only apply to the foreshore.

Current protection in marine areas beyond 12 nautical miles is limited to measures taken under the EU Birds and Habitats Directives or the OSPAR Convention. This means that habitats and species that are not listed in the EU Directives, but which may be locally, nationally or internationally important, cannot currently be afforded the necessary protection

Yes. In late March 2022, Minister for Housing Darragh O’Brien said that the Government had begun developing “stand-alone legislation” to enable identification, designation and management of MPAs to meet Ireland’s national and international commitments.

Yes. Environmental groups are not happy, as they have pointed out that legislation on marine planning took precedence over legislation on MPAs, due to the push to develop offshore renewable energy.

No, but some activities may be banned or restricted. Extraction is the main activity affected as in oil and gas activities; mining; dumping; and bottom trawling

The Government’s expert group report noted that MPA designations are likely to have the greatest influence on the “capture fisheries, marine tourism and aquaculture sectors”. It said research suggests that the net impacts on fisheries could ultimately be either positive or negative and will depend on the type of fishery involved and a wide array of other factors.

The same report noted that marine tourism and recreation sector can substantially benefit from MPA designation. However, it said that the “magnitude of the benefits” will depend to a large extent on the location of the MPA sites within the network and the management measures put in place.
