#NEW IRISH LIGHTHOUSE – The first lighthouse of a new generation to dot the Irish coastline was officially 'switched-on' at Roancarrigmore, a small island marking the eastern entrance to Castletownbere Co. Cork, writes Jehan Ashmore.

The ceremony was performed by Minister for Agriculture, Food and Marine, Simon Coveney, T.D. Constructed of stainless steel the new structure stands only 8.5m high and is sited at the foot of the original lighthouse that towers above, where there has a light since 1847 to warn shipping to the dangers of the rocky island.

The Commissioners of Irish Lights have taken an international lead in developing this new state of the art lighthouse, which beyond technical advances is also geared to make significant cost savings due to very low maintenance requirements.

In addition there will be environment benefits from the replacement of diesel generation by renewable energy and the ending of waste-water and refuse disposal.

The lighthouse has a low-voltage LED Light and provides a clearer quality of light and is far more reliable than traditional filament lamps. The new lighting system is powered using 12 x 50W solar panels to replace the masonry tower which had a 100 Volt, 1,500 Watt filament lamp and diesel generators.

The sectored light will be supplemented and monitored by Automatic Identification System (AIS) functionality which advises the mariner directly on their bridge of the status and position of the light.

AIS is a key component of the International Maritime Organisation e-Navigation project and will ensure Roancarrig is equipped to take advantage of this initiative.

In addition there are proposals to examine possible new uses for the older lighthouse which is adjoined by a former lighthouse-house keeper dwelling used by previous generations before automation took over.

#MARINE RESCUE EXERCISE-By coincidence two separate emergency exercise practise drills took place yesterday off Dalkey Island, the first involved a 12,921dwt tanker in broad daylight while the second exercise involved lifeboats under pitch-dark conditions, writes Jehan Ashmore.
The tanker Cumbrian Fisher (PHOTO) had arrived in the afternoon, anchoring unusually close to the island, to the south-east off The Muglins Lighthouse (to read more click HERE). While waiting for a berth in Dublin Port, she engaged in a lifeboat-drill practice which involved launching an orange-coloured fully enclosed lifeboat which was lowered into the water from the vessels' stern cradle-crane.

Crew kitted in similarly bright orange coloured sea safety-survival suits entered the lifeboat before it plunged into the water. The activity was observed through the binocular-scope which overlooks Coliemore Harbour with excellent views across the sound to Dalkey Island, Dublin Bay and Howth Peninsula.

The binocular-scope does not require payment to operate and was unveiled in 2008 in memory of local resident the late Dr. John de Courcy Ireland, the 'father' of maritime Ireland (to read more click HERE). He was for 26 years a honorary secretary of the local RNLI station in Dun Laoghaire and a staunch campaigner of Irish maritime affairs.

Each Monday a routine lifeboat practice is conducted by the 47ft Trent class ALB (all-weather lifeboat) RNLB Anna Livia (info and PHOTO). Last night's drill also involved the new D-class ILB (inshore lifeboat) RNLB Réalt na Mara which was named earlier this year by Kathy Kenny, wife of RTE presenter Pat Kenny.

Under the cover of darkness the crew of the ILB Realt na Mara simulated an 'injured casualty' on the island where the casualty was prepared to be taken off by stretcher from the island's small harbour. From there the casualty was transferred to the larger RNLB Anna Livia which lay offshore. During the exercise, powerful searchlight beams from the ALB provided essential light to assist in the transfer operation.

Asides the lifeboats, there is plenty of wildlife to observe on the rocky outcrops at Maiden Rock, Clare Rock and Lamb Island, which forms the second largest island after the main island of 22-acres, where a resident herd of goats have been part of the local community for over 200 years.

As for the South Korean built Cumbrian Fisher, she too has close connections with these waters as she was named in Dublin Port in 2005. She is a frequent caller to Dublin bringing bulk liquid products from the oil refinery in Milford Haven, Pembrokeshire which is a major supplier, serving the demands of the capital.

Dublin Port has two oil jetties which cater for four tankers, where bitumen, chemicals, liquid petroleum gases, molasses and oil are handled on a 41-hectare zone with storage for 330,000 product tonnes to include 6,000 tonnes of LPG. In addition aviation fuel is frequently delivered to the terminal to satisfy the constant demand for aircraft using Dublin Airport.

Cumbrian Fisher alongside her sister Clyde Fisher where built for James Fisher & Sons and in recent years they have tended to take anchorage off Dalkey Island and off the Nose of Howth. In comparison the vast majority of vessels anchor in Dublin Bay which is divided into quadrants for the purposes of anchorage allocation.

Before the completion of the South Wall in Dublin Port, which considerably improved safer access of vessels entering the River Liffey, it was the relative deeper and sheltered waters of Dalkey Sound which were used instead as Dalkey acted as the principle port for Dublin between 14-17th centuries.

Vessels would convey cargoes which were taken to and fro by lighter to the coast where it was carried by horse and cart to nearby Dalkey before onward travel across the exposed plains to Dublin City.

Ambitious plans to introduce load-on load-off (Lo-Lo) facilities at Rosslare Europort have been announced, according to a report in yesterday's Wexford People.

 
John Lynch, manager of the port talked about the expansion of the ports current role which is exclusively for roll-on roll-off (Ro-Ro) ferry business into Lo-Lo traffic and the eventual development of a rail-freight terminal.

However, to facilitate all these developments, Mr Lynch said they will need the reclamation of up to 20 hectares of additional land and the deepening of part, or all, of the port from the current 7.2m to 9m and perhaps, eventually, 11m.

Mr Lynch said these developments would be facilitated, and accelerated, by of a port centric logistics zone (a grouping of activities dealing with freight transportation) on lands beside the south-eastern port.

Mr Breen said he recognises the 'fundamental and strategic importance of Rosslare Europort to the economic development of the county'.

The county manager said he will recommend that 'appropriate policies, objectives and development management standards are included in the draft plan to facilitate the development of the port', subject to the appropriate technical and environmental assessments.

As part of his submission, Mr Lynch also requested that the '1902 Lighthouse' at the port, which is recognised on the National Inventory of Architectural Services, not be included on the Record of Protected Structures.

Mr Breen said he would give further consideration as to whether it would be appropriate to de-list the lighthouse in advance of the draft plan.

Next month the port will host the annual Irish Ports Conference in the Ferrycarrig Hotel, Wexford on Friday 30 September.

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.
