The latest Marine Notice from the Department of Transport gives advance notice of the discontinuation of the Differential Global Positioning System (DGPS) service around the coast of the island of Ireland from 31 March 2022.

DGPS has been provided as an augmentation service of the GPS signal by the General Lighthouse Authorities in Ireland and the UK since 1997.

The Commissioners of Irish Lights, in consultation with the Department of Transport, have resolved that the DGPS service has now become redundant and has decided to discontinue the service in waters around the coast of the island of Ireland after 31 March 2022.

Further information and guidance for maritime users is available on the Irish Lights website. This explains the background, consultation with the wider DGPS user group and guidance for maintaining the safety of navigation after the DGPS service ceases next spring.

#Lifejackets - The Sunday Independent writes on Donegal firm Mullion Survival Technology's new innovative lifejackets that come with the latest tech to ensure help comes quickly.

The compact design sits like a collar around the user, with plenty of room for movement, but most important is the built-in GPS beacon that pinpoints the location of the user to rescuers, and a bright light that activates automatically once they hit the water.

What's more, each Mullion lifejacket is registered to a particular user, so that emergency services can know exactly who they're searching for when the alarm is raised.

Mullion's devices have already been credited with saving the life of a fisherman off Co Down, as previously reported on Afloat.ie, and as of this year will be the standard personal flotation device (PFD) for the Irish fishing fleet.

#Navigation - Marine navigation systems in yachting and shipping are 'primitive' compared to the standard in air travel, according to an electronics expert.

As Yachting Monthly reports, Martin Bransby of the UK's General Lighthouse Authorities said that "demands on marine navigation are only getting tighter, yet electronic systems at sea a primitive compared to those used in air travel. This needs to change."

Bransby made his comments following a trial to tackle the problem of rogue GPS jammers in the North Sea by the lighthouse authorities at Trinity House.

The new PNT (positioning, navigation and timing) method uses new technology to transmit critical data in the even of the loss or failure of GPS, which is vulnerable to interference from a variety of sources, both environmental and deliberate.

"The more dependent we become on electronic systems, the more resilient they must be," said Bransby. "Otherwise, we face a scenario where technology is actually reducing safety rather than enhancing it."

These new trials come after news that the Irish Coast Guard is collaborating on a new system of marine monitoring that will help detect drifting or rogue vessels in international waters before they become a problem for individual states - such as the 'ghost ship' MV Lyubov Orlova which as of last week was still adrift heading eastwards somewhere in the North Atlantic.

The Irish GPS Speedsailing record fell again last Friday in Dungarvan when Oisin Van Gelderen broke all previous speeds, becoming the fastest sailor ever to sail on Irish waters.

The speed is ratified by the WGPSSRC (World GPS Speedsailing Records Council):  
http://www.gps-speedsurfing.com/default.aspx?mnu=records, who issue GPS records based on the best 10 second run of 45.02 knots, and a distance travelled of around 270 metres in this time.

The 5 x 10second run average, currently puts him in fourth overall on the 2011 GPS speed ranking list and 23rd overall in the all time rankings.
Peak speed for the day was 46.32 knots (84 kmph), and 500m speed was 43.96knots.

Even though Van Gelderen broke the late John Kenny's 500m speed, he retains that title for now, as the WSSRC (World Speed sailing Records Council) issue National records for that distance, and do not yet recognize GPS.

The rise in popularity in GPS speedsailing has made the competition a worldwide phenomenon, as people from different countries compete year round to push their personal and international speeds. Over 4000 members subscribe to the gps-speedsurfing.com website.

Boating electronics provider Raymarine was saved from collapse over the weekend with a last-minute buyout.

Negotiations with a 'third party', which turned out to be the eventual purchaser, broke down momentarily, with GPS company Garmin making a last-ditch bid to buy the company. The bid would have been subject to receiving the green light by competition authorities.

Raymarine plc was forced to go into administration when its banking consortium withdrew finance on May 13, casting the future of the company into some turmoil.

As a result, Raymarine plc was put into administration on Friday, with all the working business elements of Raymarine Holdings then immediately sold out of adminstration to the original third party.

The eventual purchaser was Flir Systems, a US-based thermal imaging company, which bought Raymarine at a valuation of £124 million, making a 20-pence-per-share return to shareholders. The purchase price includes Raymarine's debt, which has been put at close to £100million, but the per-share return may diminish further once creditors claims come in.

Although Garmin's per-share bid was higher (£0.35 per share), the immediacy of the Flir bid made it more palatable to the administrators.

The transaction ensures business as usual for Raymarine customers and suppliers.

Raymarine is one of the world's leading radar, GPS and marine instrumentation brands. Flir are a major manufacturer of thermal imaging cameras

All documents relating to the sale can be viewed on Raymarine's investor relations page.

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.
