Iceland has selected Galway as the European landing location for international telecommunications cables.

Farice, a company fully owned by the Icelandic Government, currently owns and operates two submarine cables linking Iceland to Northern Europe.

It has been undertaking preparatory work for a new submarine fibre cable from Iceland to Europe since early 2019.

A survey ship named Ridley is now exploring suitable seabed approaches from Galway out to the boundary of the Irish exclusive economic zone (EEZ).

Farice chief executive officer Thorvardur Sveinsson said that “after careful consideration of many factors, Galway was selected by Farice as the European cable landing location”.

“The Icelandic landing site will be on the Reykjanes peninsula with the final location to be decided during the winter 2020/2021,” he said.

“ This coupled with Galway’s reputation for business, education and hospitality will lead to a win-win situation. The enhanced global activity provided by the system will be a catalyst for attracting high tech business to the city and the regions,” he said.

The company said the project could result in a new submarine fibre cable between Iceland and Ireland becoming operational within two years from financing being secured.

“Ireland has many important attributes that make it attractive as a destination for this new cable from Iceland, over and above the relatively short distance between the two countries,” Mr Sveinsson explained.

“Ireland is at the nexus of new trans-Atlantic connections, is a centre of choice for European operations for many international businesses and has a rich and diverse pool of skilled labour in its workforce. Ireland has thus firmly established itself at the forefront of the development of Europe’s digital infrastructure and as such is an important connection point for a new submarine cable between Iceland and Europe,” he said.

“It is often perceived that international telecommunications are carried out by satellite. This is a common misconception and in reality, the vast majority of global communications is carried on fibre optic cables and particularly sub-sea cables,” he explained.

“The capacity of such cables is quite incredible and a single pair of fibre strands could satisfy the demands of most of Galway city,” he said.

“Due to the very high capacity of modern systems, subsea fibre cables are incredibly small in size (approx. 25mm diameter) and are very fast and non-intrusive to install. The overall benefits greatly outweigh the short-term inconvenience during the installation,” he said.

“The presence of the Farice system landing in Galway will provide direct high capacity links to Iceland but also to Northern Europe via Denmark and the UK and will greatly increase capacity and connectivity in Galway city and the regions,” he added.

The company currently operates the FARICE-1 cable between Iceland and Scotland with a branch connection to the Faroe Islands and the DANICE submarine cable between Iceland and Denmark.

A third submarine cable Greenland-Connect links Iceland to Canada and US. The Icelandic government said the fourth cable would “increase further the security and resiliency of Iceland’s international telecommunications.”

The new cable could cost up to €2 million during the research phase, with the actual laying estimated last year at around 32 million US dollars.

#Subsea - The Irish Times has more details on the new transatlantic subsea internet cable Hibernia Express, work on which got underway this past March.

Clearance and pre-laying work continued this month in the Celtic Sea to prepare for the arrival of the 4,600km fibre optic cable in Cork Harbour in the coming weeks.

Once connected to the new Cork Internet Exchange (CIX), it will be the first modern telecommunications cable of its kind to link North America and Europe in well over a decade.

And its speed and capacity – offering the lowest latency between New York and London – will be a boon for businesses that depend on the fastest possible and most robust data connections.

Combined with the shorter Ireland-France Subsea Cable, it's also set to make Cork a leading global internet switching centre, eliminating the need for Ireland's internet traffic to go through the UK before the rest of the world, as TechCentral reports.

#HiberniaExpress - The Department of Transport, Tourism and Sport advises that TE SubCom, on behalf of Hibernia Express, is carrying out a route clearance operation and a pre-lay grapnel run along the Hibernia Express cable route using the M/V Ile d’Aix (Callsign FICI) and M/V Atlantic Guardian (Callsign HO6566.

The operations, which follow earlier work on the same subsea cable route in March, commenced on 17 and 13 May 2015 respectively are expected to last until the end of June 2015, weather permitting.

The vessels will be towing grapnels astern at a distance depending on water depth, and as such, will be restricted in their ability to manoeuvre.

All vessels are requested to give these operation a wide berth. The project vessels will be listening on VHF Channel 16 throughout the project.

Details of co-ordinates for both vessels' work areas are included in Marine Notices Nos 18 and 19 of 2015, available to read or download HERE and HERE.

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.
