Shannon Estuary Dolphins at Risk From Green Energy Projects, Warns IWDG

The Shannon Estuary’s resident population of bottlenose dolphins could be under threat from plans to transform the area into a green energy hub, a conservation group fears.

Plans revealed last month in the final report of the Shannon Estuary Economic Taskforce envisage the delivery of up to 30GW of power from offshore wind energy projects in the estuary by the year 2015.

But according to the Irish Examiner, the news has prompted concern from the Irish Whale and Dolphin Group (IWDG) for the status of the estuary’s protected and unique dolphins.

Marine wildlife such as dolphins are especially sensitive to noise from human activity, such as that which would be involved in the construction and maintenance of offshore wind farms and other green energy infrastructure.

“We are lucky to have these dolphins, they are unique and it would be a tragedy if they were not there anymore in 30 years,” said the IWDG’s Dr Simon Berrow — who added that he has yet to receive a response after reaching out to Taoiseach Leo Varadkar, Environment Minister Eamon Ryan and the taskforce.

We've got a favour to ask

More people are reading Afloat.ie than ever thanks to the power of the internet but we're in stormy seas because advertising revenues across the media are falling fast. Unlike many news sites, we haven’t put up a paywall because we want to keep our marine journalism open.

Afloat.ie is Ireland's only full–time marine journalism team and it takes time, money and hard work to produce our content.

So you can see why we need to ask for your help.

If everyone chipped in, we can enhance our coverage and our future would be more secure. You can help us through a small donation. Thank you.

Marine Wildlife Around Ireland One of the greatest memories of any day spent boating around the Irish coast is an encounter with marine wildlife.  It's a thrill for young and old to witness seabirds, seals, dolphins and whales right there in their own habitat. As boaters fortunate enough to have experienced it will testify even spotting a distant dorsal fin can be the highlight of any day afloat.  Was that a porpoise? Was it a whale? No matter how brief the glimpse it's a privilege to share the seas with Irish marine wildlife.

Thanks to the location of our beautiful little island, perched in the North Atlantic Ocean there appears to be no shortage of marine life to observe.

From whales to dolphins, seals, sharks and other ocean animals this page documents the most interesting accounts of marine wildlife around our shores. We're keen to receive your observations, your photos, links and youtube clips.

Boaters have a unique perspective and all those who go afloat, from inshore kayaking to offshore yacht racing that what they encounter can be of real value to specialist organisations such as the Irish Whale and Dolphin Group (IWDG) who compile a list of sightings and strandings. The IWDG knowledge base has increased over the past 21 years thanks in part at least to the observations of sailors, anglers, kayakers and boaters.

Thanks to the IWDG work we now know we share the seas with dozens of species who also call Ireland home. Here's the current list: Atlantic white-sided dolphin, beluga whale, blue whale, bottlenose dolphin, common dolphin, Cuvier's beaked whale, false killer whale, fin whale, Gervais' beaked whale, harbour porpoise, humpback whale, killer whale, minke whale, northern bottlenose whale, northern right whale, pilot whale, pygmy sperm whale, Risso's dolphin, sei whale, Sowerby's beaked whale, sperm whale, striped dolphin, True's beaked whale and white-beaked dolphin.

But as impressive as the species list is the IWDG believe there are still gaps in our knowledge. Next time you are out on the ocean waves keep a sharp look out!
