Volunteer coastal cleaners in East Cork have gained the support of the joint venture behind a new proposed offshore wind farm project to boost their efforts in tackling the scourge of marine litter on the Irish coast.

As the Irish Examiner reports, Clean Coasts Ballynamona have inked a sponsorship deal with the Inis Ealga Marine Energy Park which will enable them to purchase a boat and other equipment to expand their abilities to clean and protect some 80km of coastline.

Clean Coasts Ballynamon comprise more than 300 volunteers who do regular beach cleans — and also manage 34 acres of coastal habitat to promote biodiversity in East Cork.

DP Energy Ireland Ltd is undertaking geophysical surveys at the proposed Inis Ealga Marine Energy Park off Cork and Waterford, outside the 12-nautical-mile limit.

Works were set to begin on Friday 2 September and last for five days, subject to weather, carried out from the ILV Granuaile (callsign EIPT) on a 24-hour basis.

The reconnaissance geophysical survey is being performed using a hull-mounted multibeam echosounder (MBES) and towed seismic system (maximum towed length 60m), running widely spaced lines across the array investigation area.

Communication on marine band radio VHF Channel 16 will be conducted with other ships and vessels to notify them of the operations.

In addition, ILV Granuaile is restricted in its ability to manoeuvre during this operations and will display appropriate shapes and lights. All other vessels operating within this area are requested to keep their distance and pass at a minimum speed to reduce vessel wash.

Coordinates and a map of the survey area as well as contact details are included in Marine Notice No 60 of 2022, attached below.

DP Energy, one of Ireland’s leading developers of renewable energy projects, is planning to carry out a geophysical survey beyond the 12 nautical mile limit at their proposed Inis Ealga Marine Energy Park off the coasts of Cork and Waterford.

The survey, which will cover approximately 900 Km2, will begin on 8th September and will take place for a period of five days. The work will be undertaken by Hydrographic Surveys of Crosshaven onboard the Commissioners of Irish Lights vessel, ILV Granuaile, a multifunctional ship which is equipped to operate in difficult sea conditions.

The Inis Ealga Marine Energy Park is a 1,000 MW (1GW) offshore wind project which will use floating platform technology anchored to the seabed. Once operational, the proposed wind farm will generate enough clean renewable energy to power the equivalent of nearly one million homes. Delivery of this scheme, planned to be operational by 2030, will significantly contribute to Ireland’s Climate Action Plan target of 7 Gigawatts of offshore wind energy by 2030 and the longer-term target of net-zero emissions by 2050.

To develop the Inis Ealga Marine Energy Park project, DP Energy has partnered with global energy leader Iberdrola, one of the world’s largest renewable energy producers. Iberdrola has substantial experience in offshore wind development and, importantly, shares DP Energy’s commitment to a sustainable and ethical approach to development.

The upcoming survey of the Inis Ealga Marine Park location will provide valuable information on the make-up of the seabed and this will be used to inform the project design, siting of turbines and construction methods for the proposed park. The results will also assist in the preparation of specifications for additional future geophysical and geotechnical surveys.

Adam Cronin, Head of Offshore at DP Energy, outlines the processes that will be used:

“The equipment we are planning to use includes a hull mounted multibeam sonar and sub bottom profiler. This survey will provide information about the seabed make-up at various depths. We will be able to image the sediment and rock layers beneath the surface of the seabed giving us crucial information on sediment layers for design. The data obtained from the surveys will be utilised in the design of the project and the design will be in the public domain as part of the Development Consenting process.”

Commenting on the announcement Dave Ward, Commercial Manager at Commissioner of Irish Lights said: “Granuaile is a key asset of Irish Lights in delivery of its navigation safety service around the coast of Ireland. Irish Lights can provide a range of services, statutory and commercial to support local partners in the transition to offshore renewable energy. We are pleased to support DP Energy to enable and harness Irish natural resources in offshore wind, in order to drive the establishment of an indigenous Irish supply chain while underpinning marine based employment.”

Headquartered in Buttevant in North Cork and operating across the world, DP Energy is committed to using the most sustainable and environmentally responsible methods in all of their energy developments. Currently, DP Energy has a 5,000+ megawatt (MW) portfolio of wind, ocean and solar energy projects in development stages across Ireland, Australia, the UK and Canada.

In addition to the Inis Ealga project, DP Energy, in conjunction with Iberdrola, has also submitted Foreshore Licence applications for Clarus Offshore Wind Farm, off the coasts of Clare and Kerry (floating) and Shelmalere Offshore Wind Farm, off the coasts of Wicklow and Wexford (fixed).

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.
