Ireland’s first Marine Notice of 2023 is out of this world — quite literally, as it advises of potential hazard at sea from a satellite rocket launch from Cornwall next week.

Virgin Orbit has designated a space launch hazard area off the South West Coast active from 10pm on Monday 9 to 1am on Tuesday 10 January, subject to weather and operational constraints.

Where the launch attempt proceeds as planned, no debris will enter this area. However, there is a low probability for the vehicle to produce dangerous debris if a mishap were to occur, Virgin Orbit says.

Mariners are advised to avoid the marine hazard area during and leading up to the launch period due to possible dangerous conditions from potential rocket debris.

More precise details of the launch will be promulgated though the MSI service by the Irish Coast Guard and UK;s HM Coastguard on VHF, MF and NAVTEX broadcasts, five days before the launch.

Virgin Orbit says it will be taking every step possible to monitor the area during the launch attempt. Mariners are advised to report any debris or pollution sightings in the event of a launch mishap.

Backup launch dates as well as relevant coordinates, a map and contact details can be found in Marine Notice No 1 of 2023, attached below.

#Fishing - Who's watching out for illegal fishing in the world's oceans? It could be anyone at the click of a mouse of the tap of a touchscreen – if a new satellite tracking programme takes off.

NPR's The Salt blog reports on the Eyes on the Seas project, that aims to help authorities the world over keep tabs on illegal fishing activity via a 'virtual watch room' that combines satellite imagery with real-time location data.

The inspiration for the project is the recently launched Global Fishing Watch system. As reported on Afloat.ie last November, this uses specialised software from a small start-up called SkyTruth, which maps AIS data onto satellite maps of the oceans to track the activity of fishing fleets around the world.

The project has the backing of internet giant Google, and now SkyTruth's John Amos has partnered with the Pew Charitable Trusts on the latest version of the initiative to use technology against the ocean's seafood pirates.

#MarineScience - Irish companies and researchers have distinguished themselves by developing innovative maritime services using satellite derived data in areas as diverse as marine renewables, fisheries protection, aquaculture and tourism.  

That was the message from Dr Volker Liebig, director of Earth observation programmes with the European Space Agency at the opening of a conference on 'Space Innovation - Powering Blue Growth' at the National Maritime College of Ireland in Cork last week.

Minister for Research and Innovation Sean Sherlock, who opened the two-day event, said: “There are over 40 Irish companies currently engaged in ESA programmes, many of which are directly addressing global challenges such as climate change, sea-level rise, maritime surveillance and marine environmental monitoring.

"This is a growing industry and one which will guarantee high-quality jobs for Irish people and benefit our economy into the future.”

The conference - jointly organised by the ESA, the European Commission (DG Maritime Affairs), Enterprise Ireland, University College Cork’s Coastal and Marine Research Centre, the Irish Coast Guard and the Irish Naval Service - focussed on the contribution of space to maritime policy implementation; showed how new scientific results and innovative services assist in achieving targets set by the Integrated Maritime Policy for the European Union (IMP); and assessed how the ESA space development activities and the IMP can contribute to economic growth in Europe.
   
Geoffrey O’Sullivan, representing Marine Institute CEO Dr Peter Heffernan, said that the conference "ably demonstrated that Space Remote Sensing had a very positive contribution to make towards developing our blue economy.”

Examples given included fisheries management (including illegal, unreported and unregulated fishing); environmental assessment; detection of oil spills and harmful algal blooms; site survey for offshore renewable energy and aquaculture platforms; search and rescue; and maritime domain awareness (MDA).

O'Sullivan added that the Conference "validated the SMARTOCEAN (ICT and the Sea) Strategy being promoted by the Marine Institute, in identifying clear opportunities for Irish researchers and SMEs to harness their significant ICT and marine research skills and drawing on 'Big Data' provided by satellite sensors to develop of range of new products, services and applications relevant to local and global markets.”

Closing the conference, Marine Minister Simon Coveney commented that “increasing maritime situational and domain awareness is paramount in promoting a more inclusive approach to maritime development in delivering both the EU Blue Growth Strategy (2012) and Ireland’s Integrated Marine Plan (Harnessing Our Ocean Wealth) launched in 2012.

"Space based systems,” he said, “are a key component of an integrated and sophisticated maritime surveillance network.”

#Coastguard - The Irish Coast Guard is collaborating on a new system of marine monitoring in the hopes of detecting a dead ship that may threaten to run aground on Ireland's shores.

The Newfoundland Shipping News blog details how the MV Lyubov Orlova, adrift somewhere in the North Atlantic, is being used to test the capabilities of a new system called Global Maritime Awareness.

The system is based on the idea that if the world's top satellite tracking technologies could be banded together, it could establish a much more comprehensive monitoring system for the marine environment.

Marine surveillance expert Guy Thomas, who devised the concept, said he had the idea that if a receiver akin to that used in the Automatic Identification System (AIS) for ship tracking and collision avoidance was put on a satellite in orbit, "you would now have the international identification system for ships that was lacking".

That was done, and a second accompanying system was added that provides radar information from space. The Global Maritime Awareness system combines those with detailed satellite imagery, and Long Range Identification and Tracking {LRIT) technology whereby ships can verify themselves to others and the systems tracking them.

Thomas says these four satellite systems working in tandem make for "a very effective tool in monitoring marine environments for illegal activity".

But it can also be used to prevent potential environmental catastrophes - which is where the MV Lyubov Orlova comes in.

The Irish Coast Guard's director Chris Reynolds contacted Thomas with its concerns that the dead ship might drift into Irish waters and become a burden on the State. Thomas suggested using his system to find it, almost like an ocean-wide version of the game Battleships: even when a ship isn't sending any signals, it can still be tracked, just by looking for ships that aren't transcending through AIS.

Thomas and the Irish Coast Guard are currently working hard at this, crossing off vessels that are communicating through satellite systems till they can narrow it down to the one they're looking for. And they may now have a hit south-southeast of Greenland, although it will be some days before they can confirm.

While it might be an exaggeration to say that all of the 21 crew members of Rambler 100 owe their lives to the Irish Search and Rescue service, there are certainly five people whose future prospects were greatly improved by the operation off the Fastnet Rock on August 15th. A lot of media focus has been on Coxswain Kieran Cotter and the crew of Baltimore Lifeboat as well as lifeboat mechanic Jerry Smith, whose dive boat, on charter to the media team of one of the competitors, was on hand to search and recover the five drifting crew. There is no question that this focus is appropriate. RNLI crews all over the UK and Ireland deserve the attention, not only because of their extraordinary voluntary dedication to the cause, but also because such publicity helps swell the coffers of the charity. The service could not operate without the generosity of the donors and incidents such as these help fill the blue boat-shaped boxes held by even more RNLI volunteers.

The dramatic stories and pictures dominating the media show the front line of a quite wonderful resource that is Search and Rescue in Ireland today. Baltimore Lifeboat was at the coal face of an intricate network of operations, triggered by the crew's EPIRBs. Irish Coast Guard radio officers in Valentia responded almost immediately tasking the rescue resources, working the phones and computers to confirm that this was not an accidentally triggered EPIRB, contacting RORC HQ, determining search patterns and relaying the information to the scene. It was the backroom contacts between RORC and the Coast Guard in endeavouring to contact Rambler 100 using satellite phones that confirmed the possibility of a catastrophic incident involving the Supermaxi. The subsequent tasking of the Shannon and Waterford based Sikorsky helicopters led to the medevac of crew member Wendy Touton and timely treatment of her hypothermic condition, initially by the on-board paramedics and later at Tralee General hospital. And Coast Guard involvement didn't end with the successful rescue – the shoreside operation to provide food and shelter in Baltimore was coordinated by Coast Guard personnel and the salvage operation of the hull of Rambler 100 was overseen by the Irish Coast Guard.

That Ireland has probably one of the best Search and Rescue services in the world goes back to the campaign initiated in 1988 by Joan McGinley, following the death, within sight of land of Donegal fisherman John Oglesby, whose leg was severed in a trawl winch. Eamon Doherty, the late former Garda Commissioner chaired the review group established in response to the campaign and his report led to the establishment of the Irish Marine Emergency Service, subsequently the Irish Coast Guard. Under the guidance of Director Capt Liam Kirwan, the new service moved quickly to become not only the central co-ordinating body for Search and Rescue, but developed its own resources, notably the helicopters, previously tasked in from Irish Air Corps and UK SAR.
Another element that will feature in the Rambler 100 incident is the Marine Casualty Investigation Board (MCIB), set up from recommendations arising from a review of the handling of investigations into marine casualties.

It might be thought that the incident is now closed, but there are many unanswered questions and the investigation will be looking at these and making recommendations that should improve safety in this sector. These questions will include EPIRB performance, liferaft deployment and grab bag usage, but perhaps the key issue yet to be determined is why the response from fellow competitors didn't appear to happen. Even if Channel 16 wasn't being actively monitored, and if not why not, shouldn't the Mayday set off by the Coast Guard have set off the DSC alerts on the radios of Rambler 100's fellow competitors? Had the incident occurred several hours later or earlier when Rambler 100 could have been up to 100 miles from the nearest land, when conditions worsened, we could be looking at much more serious consequences.

It is heartening to think that, in this small country of ours in troubled times, not only do we have a shining star in our search, rescue, recovery and restore system, involving professionals and volunteers cooperating for the greater good, we also have a system that determines the nature of incidents so that we can all learn from the experience.
And let us not forget those people and services, such as the Gardai, Navy, Army and the community of Baltimore who are outside the media spotlight who contributed to this happy ending.

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.
