An Irish artist is part of an international expedition that’s dropping hydrophones into the waters off Greenland to record the sounds of melting icebergs.

According to the Guardian, Siobhán McDonald will use the recordings from the underwater microphones in a mixed-media installation to explore human impact on the world’s oceans.

Over the next two years, the hydrophones will capture the sounds of melting Arctic sea ice and under subaquatic audio every hour — with the results being used both in scientific research and as part of a musical score McDonald will create with a composer.

“I’m interested in hearing the acoustic pollution,” the artist says. “The sea levels are rising and that will have an impact I’d imagine on the sound range and on all the biodiversity.

“Sound is fundamental in the ocean and Arctic animals. Hearing is fundamental to communication, breeding, feeding and ultimately survival. It speaks of the necessity of paying attention to the pollution we are causing to the ecosystems around us.”

#DALKEY ISLAND PROSPECT - The Irish Whale and Dolphin Group (IWDG) has joined the chorus of opposition to the proposed oil and gas exploration off Dalkey Island in Co Dublin.

As previously reported on Afloat.ie, Providence Resources has applied for a foreshore licence to search for oil or gas about 6km out to sea on the Kish Bank Basin.

But the prospect has provoked a split in the local community over the potential risks and benefits, with many calling for a public enquiry into the licence before it is granted.

This evening an urgent meeting in Dun Laoghaire will address the public's concerns, which have been echoed by the IWDG.

"The Kish Bank and adjacent waters are important for cetaceans," said the group in a statement. "In addition, sightings of bottlenose dolphins have increased dramatically in the area following the presence of a group of three individuals since August 2010."

The IWDG is concerned about the potential effects on dolphins and porpoises that "could due to noise generated from the drilling process", noting that "there is little published data on the intensity and effects of sound generated by drilling".

Protest group Protect Our Coast has launched a online petition against the Dalkey Island Prospect citing concerns over the proximity of the drilling area to the mainland as well as the Special Protection Area of Dalkey Island, which is a haven for marine wildlife.

Naval Visits focuses on forthcoming courtesy visits by foreign navies from our nearest neighbours, to navies from European Union and perhaps even those navies from far-flung distant shores.

In covering these Naval Visits, the range of nationality arising from these vessels can also be broad in terms of the variety of ships docking in our ports.

The list of naval ship types is long and they perform many tasks. These naval ships can include coastal patrol vessels, mine-sweepers, mine-hunters, frigates, destroyers, amphibious dock-landing vessels, helicopter-carriers, submarine support ships and the rarer sighting of submarines.

When Naval Visits are made, it is those that are open to the public to come on board, provide an excellent opportunity to demonstrate up close and personal, what these look like and what they can do and a chance to discuss with the crew.

It can make even more interesting for visitors when a flotilla arrives, particularly comprising an international fleet, adding to the sense of curiosity and adding a greater mix to the type of vessels boarded.

All of this makes Naval Visits a fascinating and intriguing insight into the role of navies from abroad, as they spend time in our ports, mostly for a weekend-long call, having completed exercises at sea.

These naval exercises can involve joint co-operation between other naval fleets off Ireland, in the approaches of the Atlantic, and way offshore of the coasts of western European countries.

In certain circumstances, Naval Visits involve vessels which are making repositioning voyages over long distances between continents, having completed a tour of duty in zones of conflict.

Joint naval fleet exercises bring an increased integration of navies within Europe and beyond. These exercises improve greater co-operation at EU level but also internationally, not just on a political front, but these exercises enable shared training skills in carrying out naval skills and also knowledge.

Naval Visits are also reciprocal, in that the Irish Naval Service, has over the decades, visited major gatherings overseas, while also carrying out specific operations on many fronts.

Ireland can, therefore, be represented through these ships that also act as floating ambassadorial platforms, supporting our national interests.

These interests are not exclusively political in terms of foreign policy, through humanitarian commitments, but are also to assist existing trade and tourism links and also develop further.

Equally important is our relationship with the Irish diaspora, and to share this sense of identity with the rest of the World.
