#MarineNotice - The latest Marine Notice from the Department of Transport, Tourism and Sport (DTTAS) advises of a previously uncharted rock outside the approaches to Dingle's Fishery Harbour Centre.

The rocky outcrop or shoal was identified by the Geological Survey of Ireland (GSI) vessel RV Geo recently, and appears to be part of the shoreward extension of the Crow and Colleen-oge Rocks.

Full details of its depth and position are included in Marine Notice No 37 of 2013, a PDF of which is available to read or download HERE.

In other news, the Marine Institute is conducting a pipeline and platform superstructure (or 'jacket') survey in the Celtic Sea.

The survey, on behalf of Kinsale Energy Limited, was scheduled to commence last Monday 22 July and will continue till Friday 30 August.

Works are being conducted by the MV Granuaile (Call sign EIPT) which is carrying out underwater operations using a remote operated vehicle (ROV) making 0.4 to 0.7 knots over the ground. The vessel is listening on VHF Channel 16 throughout the project.

All vessels, particularly those engaged in fishing, are requested to give the MC Granuaile a wide berth and keep a sharp lookout in the relevant areas. Full details of co-ordinates are included in Marine Notice No 36 of 2013.

#MarineNotice - Marine Notice No 9 of 2013 advise of preparatory works for the installation of an offshore umbilical at the Corrib Gas Field development off Co Mayo.

Works are set to commence in early March along the route of the existing Corrib offshore gas pipeline with a route survey and pre-cut trenching by the Normand Ranger (Call sign LAMT).

A trench will be constructed from the subsea facilities and well in the Corrib Gas Field to approximately 16km offshore using a subsea plough pulled by the trenching support vessel.

This plough could trail as far as 1,700m behind the support vessel, and so all vessels in the vicinity are requested to keep a wide berth clear of the works. All vessel involved in the operations will be listening on VHF Channel 16 throughout the project.

Full details including relevant co-ordinates are included in the Marine Notice, a PDF of which is available to read or download HERE.

#NEWS UPDATE - The latest Marine Notice from the Department of Transport, Tourism and Sport (DTTAS) advises on a pipeline survey in the Celtic Sea next month.

PSE Kinsale Energy Limited will be commencing the survey of the 24" Gas Export Pipeline on 6 March 2012 using the Marine Institute vessel RV Celtic Voyager (call sign EIQN). The survey is expected to last 1 to 2 days, depending on weather conditions.

The survey will take place along the existing pipeline route in the Celtic Sea, between the shoreline at Inch Beach in Co Cork and gas platform 'Alpha'.

The RV Celtic Voyager will display appropriate lights and signals, and will be towing side scan sonar with cables of up to 200m long. A Radio Navigation Warning will be issued via the Irish Coast Guard (schedule Bravo, four times a day) prior to the vessel's arrival at the survey area. The vessel will also keep a listening watch on VHF Channel 16.

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

Further details for seafarers, including relevant co-ordinates, are included in Marine Notice No 7 of 2012, a PDF of which is available to read and download HERE.

Dublin City Council is proposing a mammoth 9km sewage outfall pipe to help make Dublin Bay cleaner - at a cost of €220m.
Herald.ie reports that the 5m-wide pipe - longer than the Dublin Port Tunnel - would dump effluent from the Ringsend treatment plant far offshore, thereby avoiding pollution in the bay and sensitive areas such as Bull Island, which recently lost its EU Blue Flag status for Dollymount Strand.
Plans for the project, which DCC head of waste Pat Cronin described as the "greenest and most economic solution" will be open to public consultation in the near future, with a timetable for completion by 2015.
The pipeline and redeveloped treatment plant will be funded via the Department of the Environment's water services investment programme.

New Minister for the Environment Phil Hogan has signed off on a key foreshore licence to Shell Ireland, paving the way for the completion of the controversial Corrib gas project.
The Irish Times reports that the licence, subject to conditions, consents for the construction of the final 8km section of pipeline linking the Corrib gas field to Shell's onshore terminal at Ballinaboy. Co Mayo.
The scheme already has approval from An Bord Pleanála, and consents approved by former acting energy minister Pat Carey. But An Taisce has sought a judicial review of the planning decision, due before the High Court on Tuesday.
Still required by the developer before any work can begin are a revised emissions licence from the Environmental Protection Agency and a safety permit from the Commission for Energy Regulation under the Petroleum (Exploration and Extraction) Safety Act 2010.

Sharks in Irish waters

Irish waters are home to 71 species of shark, skates and rays, 58 of which have been studied in detail and listed on the Ireland Red List of Cartilaginous fish. Irish sharks range from small Sleeper sharks, Dogfish and Catsharks, to larger species like Frilled, Mackerel and Cow sharks, all the way to the second largest shark in the world, the Basking shark. 

Irish waters provide a refuge for an array of shark species. Tralee Bay, Co. Kerry provides a habitat for several rare and endangered sharks and their relatives, including the migratory tope shark, angel shark and undulate ray. This area is also the last European refuge for the extremely rare white skate. Through a European Maritime and Fisheries Fund (EMFF) project, Marine Institute scientists have been working with fishermen to assess the distribution, diversity, and monthly relative abundance of skates and rays in Tralee, Brandon and Dingle Bays.

“These areas off the southwest coast of Ireland are important internationally as they hold some of the last remaining refuges for angel shark and white skate,” said Dr Maurice Clarke of the Marine Institute. “This EMFF project has provided data confirming the critically endangered status of some species and provides up-to-date information for the development of fishery measures to eliminate by-catch.” 

Irish waters are also home to the Black Mouthed Catshark, Galeus melastomus, one of Ireland’s smallest shark species which can be found in the deep sea along the continental shelf. In 2018, Irish scientists discovered a very rare shark-nursery 200 nautical miles off the west coast by the Marine Institute’s ROV Holland 1 on a shelf sloping to 750 metres deep. 

There are two ways that sharks are born, either as live young or from egg casings. In the ‘case’ of Black Mouthed Catsharks, the nursery discovered in 2018, was notable by the abundance of egg casings or ‘mermaid’s purses’. Many sharks, rays and skate lay eggs, the cases of which often wash ashore. If you find an egg casing along the seashore, take a photo for Purse Search Ireland, a citizen science project focusing on monitoring the shark, ray and skate species around Ireland.

Another species also found by Irish scientists using the ROV Holland 1 in 2018 was a very rare type of dogfish, the Sail Fin Rough Shark, Oxynotus paradoxus. These sharks are named after their long fins which resemble the trailing sails of a boat, and live in the deep sea in waters up to 750m deep. Like all sharks, skates and rays, they have no bones. Their skeleton is composed of cartilage, much like what our noses and ears are made from! This material is much more flexible and lighter than bone which is perfect for these animals living without the weight of gravity.

Throughout history sharks have been portrayed as the monsters of the sea, a concept that science is continuously debunking. Basking sharks were named in 1765 as Cetorhinus maximus, roughly translated to the ‘big-nosed sea monster’. Basking sharks are filter feeders, often swimming with their mouths agape, they filter plankton from the water.

They are very slow moving and like to bask in the sun in shallow water and are often seen in Irish waters around Spring and early Summer. To help understand the migration of these animals to be better able to understand and conserve these species, the Irish Basking Shark Group have tagged and mapped their travels.

Remarkably, many sharks like the Angel Shark, Squatina squatina have the ability to sense electricity. They do this via small pores in their skin called the ‘Ampullae of Lorenzini’ which are able to detect the tiny electrical impulses of a fish breathing, moving or even its heartbeat from distances of over a kilometre! Angel sharks, often referred to as Monkfish have a distinctively angelic shape, with flattened, large fins appearing like the wings of an angel. They live on the seafloor in the coastal waters of Ireland and much like a cat are nocturnal, primarily active at night.

The intricate complexity of shark adaptations is particularly noticeable in the texture of their skin. Composed of miniscule, perfectly shaped overlapping scales, the skin of shark provides them with protection. Often shark scales have been compared to teeth due to their hard enamel structure. They are strong, but also due to their intricate shape, these scales reduce drag and allow water to glide past them so that the shark can swim more effortlessly and silently. This natural flawless design has been used as inspiration for new neoprene fabric designs to help swimmers glide through the water. Although all sharks have this feature, the Leafscale Gulper Shark, Centrophorus squamosus, found in Ireland are specifically named due to the ornate leaf-shape of their scales.
