20th May 2021

Green Rebel Marine in Crosshaven is set to undertake a geophysical survey operation in the Celtic Sea from next week.

The survey from next Wednesday 26 May to 23 June, weather permitting, will be conducted by the Roman Rebel (callsign 2ICA5) using hull-mounted multibeam and sub-bottom profiling systems.

In addition, the vessel will be towing side-scan sonars and magnetometers using dedicated winches at cable lengths dictated by the water depth. Typically, the cable lengths will be about four times the water depth while acquiring data.

The Roman Rebel will display appropriate lights and signals and all survey operations will be conducted 24 hours a day, continuous over day and night.

Full details of coordinates of the survey areas are included in Marine Notice No 32 of 2021, which can be downloaded 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.
