The Department of Transport has been advised by Uisce Éireann (formerly Irish Water) that it will carry out a benthic survey from Wednesday 20 to Friday 22 September, subject to weather and operational constraints.

The survey will take place in the vicinity of the proposed Greater Dublin Drainage (GDD) outfall route and diffuser location, east of Portmarnock Beach and north of Ireland’s Eye.

Survey operations will be undertaken at eight sampling locations using the local work vessel Ros Áine (callsign EIZG5). The vessel will mobilise the scientific equipment from Howth and will operate onsite daily during daylight hours only.

Each sample site will be subjected to a seabed investigation where a sampler or dropdown camera will be in momentary contact with the seabed. Neither the equipment nor the vessel will be anchored to the seabed at any time.

The work vessel will display appropriate shapes and lights during operations and can be contacted via VHF Channel 16. All other marine traffic is requested to maintain a wide berth whilst operations are under way.

Coordinates and a map of the survey areas as well as contact details can be found in Marine Notice No 56 of 2023, attached below.

Coastal Notes Coastal Notes covers a broad spectrum of stories, events and developments in which some can be quirky and local in nature, while other stories are of national importance and are on-going, but whatever they are about, they need to be told.

Stories can be diverse and they can be influential, albeit some are more subtle than others in nature, while other events can be immediately felt. No more so felt, is firstly to those living along the coastal rim and rural isolated communities. Here the impact poses is increased to those directly linked with the sea, where daily lives are made from earning an income ashore and within coastal waters.

The topics in Coastal Notes can also be about the rare finding of sea-life creatures, a historic shipwreck lost to the passage of time and which has yet many a secret to tell. A trawler's net caught hauling more than fish but cannon balls dating to the Napoleonic era.

Also focusing the attention of Coastal Notes, are the maritime museums which are of national importance to maintaining access and knowledge of historical exhibits for future generations.

Equally to keep an eye on the present day, with activities of existing and planned projects in the pipeline from the wind and wave renewables sector and those of the energy exploration industry.

In addition Coastal Notes has many more angles to cover, be it the weekend boat leisure user taking a sedate cruise off a long straight beach on the coast beach and making a friend with a feathered companion along the way.

In complete contrast is to those who harvest the sea, using small boats based in harbours where infrastructure and safety poses an issue, before they set off to ply their trade at the foot of our highest sea cliffs along the rugged wild western seaboard.

It's all there, as Coastal Notes tells the stories that are arguably as varied to the environment from which they came from and indeed which shape people's interaction with the surrounding environment that is the natural world and our relationship with the sea.
