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.

Forty Foot Swimming Spot on Dublin Bay

The 'Forty Foot' is a rocky outcrop located at the southern tip of Dublin Bay at Sandycove, County Dublin from which people have been swimming in the Irish Sea all year round for 300 years or more. It is popular because it is one of few spots between Dublin city and Greystones in County Wicklow that allows for swimming at all stages of the tide, subject to the sea state.

Forty Foot History

Traditionally, the bathing spot was exclusively a men's bathing spot and the gentlemen's swimming club was established to help conserve the area.

Owing to its relative isolation and gender-specific nature it became a popular spot for nudists, but in the 1970s, during the women's liberation movement, a group of female equal-rights activists plunged into the waters and now it is also open to everyone and it is in the control of Dun Laoghaire Rathdown County Council.

Many people believe that swimming in extremely cold water is healthy and good for the immune system.

Is it safe to swim at the Forty Foot?

The Forty-Foot is a great place to swim because there is always enough water to get a dip but like all sea swimming, there are always hazards you need to be aware of.   For example, a lot of people like to dive into to the pool at the Forty-foot but there are submerged rocks that can be hazardous especially at low water.  The Council have erected signs to warn people of the underwater dangers. Other hazards include slippy granite cut stone steps that can often be covered with seaweed and of course marine wildlife including jellyfish that make their presence felt in the summer months as do an inquisitive nearby Sandycove seal colony.
