Honeycomb Reef Discovered In Waterford Estuary Could Be World's Biggest

#Biodiversity - Coastwatch volunteers taking part in events for National Biodiversity Week have discovered a massive honeycomb reef as much as a kilometre long in the Waterford Estuary.

Members of the public began checking the shore between Hook Head in Co Wexford and Annestown in Co Waterford on Monday 18 May, an area that has previously shown signs of honeycomb reefs.

But volunteers were astounded to make this latest massive discovery, and Coastwatch members are working to ascertain if it might be the biggest reef of its kind in the world, a record currently held by Saint-Malo in Brittany.

Karen Dubsky of Coastwatch Europe said "first results look very encouraging. We are looking for more surveyors to give an hour and search their shore."

Events continue till Monday 1 June for Ireland's National Biodiversity Week 2015, with today (Friday 22 May) being International Day for Biological Diversity.

Upcoming flagship events include a marine wildlife-watching trip to Lambay Island next Wednesday 27 May, but the event calendar lists a whole host of activities both around the coast and inland throughout the country.

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!
