Waterways Ireland advises users of the Royal Canal in Dublin city between Locks 1 and 5 (North Strand Road to Phibsborough) that cycleway upgrade works have recently commenced on this stretch of the canal.

This work will require closures of the canal towpaths in the area over the upcoming period throughout the year, in order to facilitate the upgrading works. Diversion signage will be erected on site where applicable.

Any effects on planned navigation passage will be advised but navigation passage will continue to be possible to arrange during works, though some additional restrictions may apply.

The cross-border body for Ireland’s inland waterways will issue further updates if appropriate, and says it thanks its users for their understanding in this matter.

Waterways Ireland advises masters of vessels on the Shannon Navigation that in-river works for the construction of the Killaloe Bypass upper bridge superstructure are progressing as planned and will continue until October 2024.

As previously reported on Afloat.ie, the bridge is being constructed around 1km downstream of the current Killaloe–Ballina bridge.

A buoyed navigational channel continues to be provided for 100 metres either side of the in-river works.

The following plant and equipment will be operating on or overhead the navigation during the upper bridge works:

  • 600t crawler crane set up on the east shore
  • Stabilising crane barge (30m x 23m x 1.88m)
  • 100t crawler crane
  • Tugboat/pusher boat
  • Dumb barge (23m x 9m) and mobile elevated work platforms
  • Safety boat
  • Landing pontoon and gangways

From next Tuesday 2 to Friday 19 April, the final steel girders will be lifted into position in the central spans of the bridge.

This is a heavy lift operation and deemed high-risk work, requiring calm waters for operation of mobile elevated work platforms (MEWP) on barges.

Masters of vessels are requested to proceed at slow speed (5 knots, no wash) with additional caution in the vicinity of the works, and to follow the instructions of the safety boat crew as there are hazards such as bridge piers, steel piles and mooring lines to navigate.

The cross-border body for Ireland’s inland waterways thanks its customers for their cooperation in relation to these works.

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.
