#MarineNotice - Marine Notice No 11 of 2017 advises that a geophysical research survey will be undertaken off the South and East Coasts of Ireland for 16 days from Tuesday 28 March.

The survey is a collaborative effort by researchers in iCRAG, the Irish Centre for Research in Applied Geosciences at University College Cork and the University of Bremen (Germany).

The aim of the survey is to collect geophysical acoustic data in the Irish sector of the Irish Sea and the northern Celtic Sea (including the Dungarvan/Waterford area). The data set will be primarily used to improve knowledge on the nature and formation of recent seabed sediments that were influenced by the Irish Ice Sheet during the last glaciation.

The survey data will help create a 3D geological model and revise existing sub-seabed models of the seabed sediments in the Irish Sea and the northern Celtic Sea.

The RV Celtic Voyager (Callsign EIQN) is scheduled to carry out the survey operations using relatively low amplitude sound sources to image into the seabed including an echosounder, a sparker and a micro air gun seismic system.

The vessel will on occasion be towing a hydrophone cable and other equipment up to a maximum of 250 metres behind the vessel. The vessel will be restricted in its movements when towing a cable astern.

There will be a regular safety message broadcasting on VHF Channel 16 throughout the project.

All vessels, particularly those engaged in fishing, are requested to give the RV Celtic Voyager and towed equipment a wide berth, and keep a sharp lookout in the relevant areas.

A map and co-ordinates of the survey areas are included in Marine Notice No 11 of 2017, a PDF of which is available to read or download HERE.

#MarineNotice - The latest Marine Notice from the Department of Transport, Tourism and Sport (DTTAS) advises that Osiris Projects were last week scheduled to begin marine survey operations off the south coast in the Celtic Sea.

The marine surveys will extend from the shoreline at two locations in Co Cork across the sea to the shoreline at two locations in northern France.

The survey was set to start on Monday 1 June 2015 to last for approximately three weeks, weather permitting. The survey will be conducted by the MV Proteus (Callsign 2HBL7).

The marine surveys will extend from the shoreline at Ballinwilling Strand (main route) and Ballycroneen Beach (alternative route), across the Celtic Sea, passing the Isles of Scilly, to the French coast west of Roscoff at Moguériec (main route) and Pontusval (alternative route).

The corridor width for each landing will be 250 metres from the high water mark to the 10-metre contour, then the corridor will widen to 500m as the route moves to France.

The survey vessel may be found running both along the corridor, and in the general vicinity of the survey corridor. The survey areas are small boxes which are shown in the detail plan HERE.

Survey operations will involve towing survey equipment on and below the water surface, up to 300m behind the vessel. All vessels, particularly those engaged in fishing, are requested to give the MV Proteus and her towed equipment a wide berth and keep a sharp lookout in the relevant areas.

Full co-ordinates for the relevant work areas are detailed in Marine Notice No 25 of 2015, a PDF of which is available to read or download HERE.

#MarineNotice - The latest Marine Notice from the Department of Transport, Tourism and Sport (DTTAS) advises that TE SubCom, on behalf of Hibernia Express, is scheduled to carry out a geophysical cable route survey extending south from Ballinspittle.

The survey involves multibeam echo-sounder bathymetry, side-scan sonar, magnetometer and sub-bottom profiling off the Irish coast from Ballinspittle, Co Cork, heading south to the 12nm limit and then into Ireland’s EEZ.

The survey will start on 21 July 2014 and will last for approximately four days, weather permitting. Works will be carried out by the vessel RV Ridley Thomas (Callsign V7JK2).

Inshore at Ballinspittle, shallow water survey operations will be carried out by RV Wessex Explorer (Callsign 2WWE).

Both vessels will be towing survey equipment up to 200m astern and will be restricted in their ability to manoeuvre while carrying out the survey. They will also be listening on VHF Channel 16 throughout the project.

All other vessels, particularly those engaged in fishing, are requested to give the RV Ridley Thomas and her towed equipment and the RV Wessex Explorer a wide berth, and keep a sharp lookout in the relevant areas.

Full details of co-ordinates and maps of the survey area are included in Marine Notice No 39 of 2014, a PDF of which is available to read or download HERE.

#MarineNotice - EGS International Ltd is scheduled today (13 June) to begin a two-day geophysical cable route survey involving multibeam echo-sounder bathymetry, side-scan sonar, magnetometer and sub-bottom profiling off the Irish coast at Killala Bay.

The survey follows from a longer exercise carried out in January this year, and will be focused inshore along a route into Killala Bay detailed by co-ordinates listed in Marine Notice No 34 of 2014, a PDF of which is available to read or download HERE.

The vessel SMS Coastal Cat (call sign EIJD6) is scheduled to carry out the work on a 12-hour operation basis and will display appropriate shapes during daylight operations and lights during night time operations and periods of reduced visibility.

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.
