IWDG Marks Another ‘Record’ Year For Cetacean Strandings

#MarineWildlife - The Irish Whale and Dolphin Group (IWDG) has expressed its dismay at another record year for cetacean standings around the Irish coast.

The first eight months of 2017 alone have seen 201 recorded strandings - up 30% compared to the same period in the last two years.

“As in recent years, the numbers of dead common dolphins recorded are very high, with 78 records for this species to the end of August 2017 accounting for 39% of all strandings,” says IWDG strandings officer Mick O’Connell, who notes that the numbers of dead dolphins washing ashore in late winter and spring has grown unusually high.

“Even in a series of years with particularly high numbers of this species stranding since 2011, 2017 is well ahead of the previous two ‘record’ years by the end of August — 66 in 2016 and 53 in 2013.

“These are, of course, minimum numbers as we don't know how many dead animals go unrecorded and also many unidentified dolphins which aren't identifiable to species level are likely to be common dolphins,” he adds.

The IWDG is currently working with the Marine Institute, Department of Agriculture and National Parks and Wildlife service on a post-mortem scheme for common dolphins, striped dolphins and harbour porpoises which is hoped will shed new light on what might be causing this alarming rise in cetacean deaths.

Meanwhile, there was more positive news from the recent all-Ireland whale watch at the end of August, where three-quarters of the 20 sites around the island recorded sightings.

Around 1,300 whale watchers and wildlife enthusiasts spotted eight species of cetacean between them — with the busiest site at Loop Head in Co Kerry, where 120 lucky visitors got to see two humpback whales, five minke whales, six bottlenose and a whopping 50 common dolphins.

Other marine wildlife species spotted around the coast included Risso’s dolphins, blue fin tuna, ocean sunfish and grey seals.

More recently, the IWDG’s Celtic Mist embarked on a week-long survey of the waters around North and West Kerry, and its crew shared a video of some of their sightings.

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.

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!
