A seabed debris clearance, environmental baseline and habitat assessment site survey will take place in licence SEL 1/11 (Barryroe) from later this month.

Barryroe is located in the North Celtic Sea, some 50 kilometres south of the Port of Cork.

The project is scheduled to commence in mid-August 2019 with the survey vessel Kommandor (callsign MCJO2) anticipated to be working on location for 16 days, excluding transit and any weather delays

Survey operations will be conducted on a 24-hour basis in different phases to include towed and non-towed operations. A fisheries liaison Officer will be on board for the duration of the survey.

Throughout the survey operations, the vessel will be displaying appropriate shapes and lights to indicate that the survey vessel is restricted in its ability to manoeuvre.

All vessels are requested to give this operation a wide berth. A listening watch will be maintained on VHF Channel 16, and the vessel will actively transmit an AIS signal.

Full details of the site survey co-ordinates are included in Marine Notice No 27 of 2019, a PDF of which is available to read or download HERE.

A shark species previously unrecorded in Irish waters has been sighted in the Celtic Sea.

A smooth hammerhead shark was reported on the edge of the continental shelf, south-west of Ireland, during a recent fisheries survey on the Marine Institute’s RV Celtic Explorer.

The sighting was made by experienced marine mammal observer John Power and bird observer Paul Connaughton during the Marine Institute’s Western European Shelf Pelagic Acoustic Survey (WESPAS).

“While scanning the ocean surface, we sighted a dorsal fin unlike anything we had encountered before,” said Power.

“It was quite different to the fins seen on basking sharks and blue sharks. After consulting available ID keys, we agreed that the shark must be a smooth hammerhead.”

The large, tall and slender dorsal fin of the smooth hammerhead shark distinguishes it from other shark species. The smooth hammerhead also has a single-notch in the centre of its rounded head and is up to four metres in length.

The species gives birth to live young and the pups are usually found in the shallow sandy waters near Florida, the Caribbean and West Africa. However, the species has been recorded as far north as England and Wales.

The smooth hammerhead was sighted during the WESPAS survey, which surveys the waters from France to Scotland and the West of Ireland each year.

Marine scientists collect acoustic and biological data on herring, boarfish and horse mackerel, which is used to provide an independent measure of these fish stocks in Irish waters. Scientists also monitor plankton, sea birds and marine mammals during this survey.

This is an exciting encounter, especially since a rare deep-water shark nursery was discovered by Irish scientists last year

Dr Paul Connolly, director of fisheries and ecosystems services at the Marine Institute, said: “Our Irish waters support a range of marine life and diverse ecosystems, including 35 known species of sharks.

“This is an exciting encounter, especially since a rare deep-water shark nursery, 200 miles west of Ireland, was discovered by Irish scientists last year using the Marine Institute's Remotely Operated Vehicle [ROV Holland 1].”

He added: “This sighting of a new shark species shows the importance of our fishery surveys to monitor our marine environment, and to observe changes in our oceans and marine ecosystems.

“Observing and understanding a changing ocean, is essential for protecting and managing our marine ecosystems for the future.”

The hammerhead shark poses little risk to humans, and there have been no known fatalities from hammerhead sharks anywhere in the world to date.

The species is listed as Vulnerable on the International Union for Conservation of Nature (IUCN) Red List of Threatened Species, and is being increasingly targeted for the shark fin trade as its large fins are highly valued.

Thirty-five species of sharks have been recorded in Irish waters, including the blue shark, porbeagle shark, lesser spotted dogfish and the second-largest shark in the world, the basking shark — a regular visitor inshore during the summer months.

#MarineWildlife - Naval Service personnel on patrol with the LÉ Samuel Beckett encountered the carcass of a large whale some 50 nautical miles south-east of Ballycotton Lighthouse in the days after Christmas.

The “mystery whale” is neither a sighting (which only counts or living cetaceans) nor a stranding. But as the Irish Whale and Dolphin Group (IWDG) says, the encounter “serves to remind us that the animals that wash up on our shoreline may represent only a small percentage of the total number of cetaceans that expire at sea of presumably natural causes.”

IWDG sightings officer Pádraig Whooley said the location of these whale remains was “interesting as this area of the Celtic Sea has produced the most consistent large-whale sightings in recent months, with fairly regular sightings of fin whales from land-based sites between Ram Head, Ardmore extending east towards the Hook Head lighthouse.”

#MarineScience - Marine Institute's RV Celtic Explorer departed Galway yesterday for the first deepwater INFOMAR survey of 2018 to map the seabed in the region of the Labadie and Cockburn Banks, south of the Celtic Sea.

These areas are of ecological and economic value to the Irish fishing fleet and the data collected will allow better fisheries management decisions.

INFOMAR, the national seabed mapping programme, is a joint programme between the Geological Survey of Ireland (GSI) and Marine Institute. INFOMAR creates bathymetric charts and products for Ireland's coastal and deeper offshore waters using acoustic sonars called multi-beams. The survey team will be led by Vera Quinlan, and include four INFOMAR surveyors / scientists and four marine science students.

Three multi-beam echo sounders on the marine research vessel will transmit beams of sound towards the sea floor. These 'beams of sound' are reflected off the sea floor and both the time it takes to receive the returned signal and the intensity are captured by the on-board systems. This process provides a very clear picture of the shape and texture of the seafloor, such as the bathymetry, and the geological characteristics of the area.

Further studies include the analysis of the radiation patterns of the sonars resulting in increased precision and improved data. This is part of a long-running collaboration between INFOMAR and Professor John Hughes Clarke at the Centre for Coastal and Ocean Mapping at the University of NewINFOMAR survey to map the Celtic Sea seabed Hampshire.

The survey team includes two students from the United States of America, Alexandra Dawson and Treyson Gillespie, from the BEAMS (BEnthic Acoustic Mapping and Survey) Program. BEAMS is an undergraduate-focused training and research program from the College of Charleston's Department of Geology and Environmental Geosciences, and aims to develop a strong and qualified workforce of ocean surveyors in support of the academic, research and operational marine communities.

INFOMAR also welcomes Becky Cronin and Rachel O' Mahoney from the Training Through Research Surveys (TTRS), a collaboration with the Marine Institute. The programme aims to increase national capacity in offshore marine research by offering seagoing placements for students of marine related sciences and technologies on the national research vessels, RV Celtic Explorer and RV Celtic Voyager.

#MarineNotice - The latest Marine Notice from the Department of Transport, Tourism and Sport (DTTAS) advises that Osiris Projects were last week scheduled to begin marine survey operations off the south coast in the Celtic Sea.

The marine surveys will extend from the shoreline at two locations in Co Cork across the sea to the shoreline at two locations in northern France.

The survey was set to start on Monday 1 June 2015 to last for approximately three weeks, weather permitting. The survey will be conducted by the MV Proteus (Callsign 2HBL7).

The marine surveys will extend from the shoreline at Ballinwilling Strand (main route) and Ballycroneen Beach (alternative route), across the Celtic Sea, passing the Isles of Scilly, to the French coast west of Roscoff at Moguériec (main route) and Pontusval (alternative route).

The corridor width for each landing will be 250 metres from the high water mark to the 10-metre contour, then the corridor will widen to 500m as the route moves to France.

The survey vessel may be found running both along the corridor, and in the general vicinity of the survey corridor. The survey areas are small boxes which are shown in the detail plan HERE.

Survey operations will involve towing survey equipment on and below the water surface, up to 300m behind the vessel. All vessels, particularly those engaged in fishing, are requested to give the MV Proteus and her towed equipment a wide berth and keep a sharp lookout in the relevant areas.

Full co-ordinates for the relevant work areas are detailed in Marine Notice No 25 of 2015, a PDF of which is available to read or download HERE.

#Oil&Gas - Kinsale Energy will take an 80% stake in Landsdowne Oil and Gas's Midleton/East Kinsale gas prospect in the Celtic Sea, as The Irish Times reports.

The deal will see the Petronas subsidiary assume 100% of costs for drilling on the prospect and will fund Lansdowne's costs of testing for up to $2.5 million.

Kinsale Energy, which was formerly Marathon Oil, already holds an interest in the Deep Kinsale Prospect beneath the Kinsale Head Gas Field, thanks to its option agreement with Fastnet Oil & Gas last year.

The Irish Times has more on the story HERE.

#Fishing - Marine Minister Simon Coveney yesterday (10 November) held a bilateral meeting with the new French Fisheries Minister Alain Vidalies in Brussels.

The meeting was organised to prepare for negotiations on the 2015 fish quotas which will be decided at the Fisheries Council on 15 and 16 December.

This was the first meeting between Minister Coveney and Minister Vidalies.

“France and Ireland have important shared fisheries in the Celtic Sea," said Minister Coveney. "I met Minister Vidalies to discuss with him the issues of importance relating to the management of these fisheries.

"I pointed out that the Irish and French fishing industries have a strong working relationship and that I wanted to ensure that this relationship is fully reflected at political level.”

The minister added: “There are particular issues arising in the Celtic Sea and our industries have worked together to bring forward measures to increase selectivity and reduce discarding of young fish. The EU Commission has proposed very severe quota cuts to the key cod and haddock fisheries.

"I agreed with Minister Vidalies that we will work closely over the coming weeks to secure agreement to a package of measures involving improved selectivity measures and set quota levels that  take into account the most up to date scientific advice.“

The EU Commission has published its proposals for Total Allowable Catches and quotas for 2015. The commission has proposed a 64% quota cut for Celtic Sea cod for 2015 and a 41% cut for haddock in the Celtic Sea. The EU Commission has yet to make its proposal for the Celtic Sea whiting and prawn quotas for 2015.

Submissions from all stakeholders have been sought by 21 November to inform a Sustainability Impact Assessment which will be presented to the Oireachtas by Minister Coveney on 2 December.

#MarineNotice - The latest Marine Notice from the Department of Transport, Tourism and Sport advises that Osiris Projects will be carrying out two survey operations along the proposed interconnector route between Ireland and France.

The surveys will extend from the Shoreline at two locations in Co Cork (Ballinwilling Strand main route and Ballycroneen Beach alternative route) across the Celtic Sea to the shoreline at two locations in Northern France (Roscoff main route and Pontusval alternative route).

The first survey operation started on 17 August and is expected to run until 30 September, weather permitting. Survey works will be undertaken on the survey vessel RRS Ernest Shackleton (Callsign ZDLSI).

The vessel will operate on a 24-hour basis, will display appropriate day shapes and lights during survey operations and will actively transmit an AIS signal.

The RRS Ernest Shackleton will be towing survey equipment below the surface up to 600m behind the vessel. A wide berth is requested at all times as the vessel will be restricted in her ability to manoeuvre.

The second survey operation was expected to start on the Irish side yesterday (10 September) and will run until 20 September, weather permitting. Survey works will be undertaken on the survey vessel MV Proteus (Callsign 2HBL7).

The vessel will operate on a 12-hour basis, will display appropriate day shapes and lights during survey operations and will actively transmit an AIS signal.

The corridor width for each landing will be 250 metres from the high water mark to the 10-metre contour, then the corridor will widen to 500 metres as the route moves to France.

The survey vessel may be found running both along the corridor and in the general vicinity of the survey corridor. The vessel will be working between high water and 20 metre contour and in daylight hours only.

The MV Proteus will be towing survey equipment on and below the water surface up to 300m behind the vessel. A wide berth is requested at all times as the vessel will be restricted in her ability to manoeuvre.

Both vessels will be listening on VHF Channel 16 throughout the works. Full details of co-ordinates of the work areas are included in Marine Notice No 55 of 2014, a PDF of which is available to read or download HERE.

Meanwhile, a hydrographic and geophysical survey operation is presently being undertaken by INFOMAR on the RV Celtic Voyager off the southwest coast of Ireland, continuing till 17 September.

The vessel is towing a magnetometer sensor with a single cable of up to 100m in length. A wide berth is requested at all times as the vessel will be restricted in her ability to manoeuvre.

The vessel will display appropriate lights and markers, and will be listening on VHF Channel 16 throughout the project.

Co-ordinates for the bounding box of the survey area are detailed in Marine Notice No 54 of 2014, a PDF of which is available to read or download HERE.

#Oil - News that the Barryroe prospect off the south coast requires a new appraisal well at a cost of some €30 million sent shares in Providence Resources tumbling on the Dublin market as trading opened today.

But the Irish oil and gas firm says there has been no setback to its plans for the oil field and "no material change" to its status, as The Irish Times reports.

And the company says it remains in discussions with "major Asian, European and North American oil companies" to tap Barryroe as a collaborative venture that's expected to be worth billions to the Irish economy.

Shares fell 9% this morning following a Sunday Times article that suggested Providence would seek funds from shareholders for new drilling in the Celtic Sea prospect.

The Half Ton Class was created by the Offshore Racing Council for boats within the racing band not exceeding 22'-0". The ORC decided that the rule should "....permit the development of seaworthy offshore racing yachts...The Council will endeavour to protect the majority of the existing IOR fleet from rapid obsolescence caused by ....developments which produce increased performance without corresponding changes in ratings..."

When first introduced the IOR rule was perfectly adequate for rating boats in existence at that time. However yacht designers naturally examined the rule to seize upon any advantage they could find, the most noticeable of which has been a reduction in displacement and a return to fractional rigs.

After 1993, when the IOR Mk.III rule reached it termination due to lack of people building new boats, the rule was replaced by the CHS (Channel) Handicap system which in turn developed into the IRC system now used.

The IRC handicap system operates by a secret formula which tries to develop boats which are 'Cruising type' of relatively heavy boats with good internal accommodation. It tends to penalise boats with excessive stability or excessive sail area.

Competitions

The most significant events for the Half Ton Class has been the annual Half Ton Cup which was sailed under the IOR rules until 1993. More recently this has been replaced with the Half Ton Classics Cup. The venue of the event moved from continent to continent with over-representation on French or British ports. In later years the event is held biennially. Initially, it was proposed to hold events in Ireland, Britain and France by rotation. However, it was the Belgians who took the ball and ran with it. The Class is now managed from Belgium.
