IWDG Proposes Seismic Survey Restrictions To Protect Migrating Whales

IWDG Proposes Seismic Survey Restrictions To Protect Migrating Whales

#MarineWildlife - The Irish Whale and Dolphin Group (IWDG) has proposed a restriction of seismic survey activity on the slopes of the Irish continental shelf and the Porcupine Seablight.

The IWDG says its move "stems from an increasing body of evidence which indicates that the Irish Shelf Slopes and Porcupine Seablight are an important migration route and opportunistic foraging area for blue whales and fin whales from August to March each year.

"Humpback whales are also known to migrate along a similar route in the winter and early spring," it added in a statement.

The cetacean conservation charity as expressed concern at what it perceives as "a large increase in seismic survey activity in the Porpcupine Seablight during the main migration period and recent evidence of disturbance to these migrating whales by seismic surveys."

As a result, the IWDG has proposed to the Petroleum Affairs Division of the Department of Natural Resources that seismic surveys – such as that scheduled to be conducted in the Porcupine Basin this September – be "restricted to the months March to August, outside of the migration period, in order to minimise disturbance to these highly endangered whale species."

According to the group "similar measures" have been successful in other parts of the world, such as off South Africa, where whales "seasonally occur in large numbers".

The IWDG's proposal is available as a PDF to download HERE.

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!
