Satellite Tracking Software Helps Manage "Pongy" Seaweed and Algal Build-up on Dublin Coast

Satellite tracking of “pongy” seaweed and algal build up has been developed by University of Galway scientists.

As The Irish Times reports, local authorities can receive complaints of seaweed accumulation, particularly from Dublin residents who may confuse it with sewage discharge.

Scientists studying the patterns of these “golden tides” – named after the colour of ascophyllum nodosum, one of the most common seaweeds on the Irish coastline - have offered their tracking software to the local authorities to help manage the issue.

The researchers from the School of Natural Sciences and Ryan Institute at the University of Galway have been studying these tides in Dublin over a seven-year period.

Led by Dr Liam Morrison and Dr Sara Harro, the University of Galway team monitored seaweed coverage at Dollymount Strand in Dublin Bay between 2016 and 2022 in relation to tides and weather.

Their BioIntertidal Mapper software analyses images from a European Space Agency satellite to help map habitats along the coastline.

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!
