#Fishing - The Marine Institute is inviting tenders for the supply of a commercial fishing vessel to conduct a boarfish acoustic survey in ICES divisions VII b, c, g, h, j & k (west of Ireland, Celtic Sea and northern Biscay).

The vessel would be chartered for a period of 21 days to survey spawning aggregations of boarfish – a big seller for Ireland in the Chinese market – using hydro-acoustic techniques.

Vessels are invited to tender on the basis of their ability to undertake the survey schedule. This comprises following a pre-determined cruise track in the order of 3,200 nautical miles carried out over 21 days with 20hr operations (4am-midnight) and with directed trawl stations on fish schools of interest as and when required.

A single pelagic midwater trawl with a vertical opening of greater than 40m and contain a 20mm codend liner and/or sprat brailer will be a requirement for the survey. A liner can be provided if required but all other associated fishing equipment must be provided by the vessel.

The survey will be timed to coincide with the southerly end point of the RV Celtic Explorer on 10 July 2015 and this survey will act as a continuation. It is therefore essential that the charter vessel is out on the water and ready to begin surveying no later than midnight on 9 July 2015.

Detailed information of the track and survey plan will be provided by the Marine Institute. The successful applicant will be selected based on technical suitability, cost of charter, pelagic fishing track record and previous experience in scientific research and surveys.

The closing date for tenders is this Friday 29 May 2015 at 12 noon. Full details of the tender are available in a PDF to read or download HERE.

#SwanCensus - Only a handful of Bewick's swans have been recorded in Ireland this winter ahead of a major international survey of migratory swans this weekend.

As RTÉ News reports, just three of the visiting waterfowl species have been sighted in Wexford so far, amid concerns that climate change is seeing them stay put in their Siberian homeland.

Whooper swans will also be counted in the latest edition of the five-yearly survey across a thousand coastal and waterside sites in Ireland this weekend, to see how numbers stand now against the 15,000 birds recorded in 2010 - half of the entire breeding population in their Icelandic home.

#MarineScience - The first underwater TV (UWTV) survey of the Bay of Biscay Nephrops grounds was carried out on the RV Celtic Voyager from 20-29 September.

This survey involved collaboration between the fishing industry and IFREMER, the French equivalent of the Marine Institute. The Celtic Voyager was chartered for this survey by the French fishing industry (CNPMEM).

The team of French scientists from Lorient were trained in the UWTV survey methodology by Jennifer Doyle, an expert from the Marine Institute. A fishing industry observer also participated in the survey.

This was the furthest south that the Irish Celtic Voyager research vessel has been to at 45°55′N 2°22′W.


The Bay of Biscay Nephrops grounds, known locally as 'la Grande Vasière', have an area of approximately 11,600 sqkm and support landings of Neprophs (better known as Dublin Bay prawns or langoustines) of around 4,000 tonnes annually.

During the 10-day survey, 160 UWTV stations were successfully completed with an average depth of 100 metres. At each station a sled-mounted camera system is towed at 1 knot. This allows for the detailed examination of the sea bed. The Nephrops burrows on the video footage collected are identified and counted by trained and experienced scientists.

Weather conditions throughout were perfect for TV operations with light winds, little or no swell and sea surface temperature around 20 degrees C. The visibility at the seabed was also excellent. The results from this survey will be analysed by IFREMER scientists to determine stock abundance.

The Marine Institute have been developing UWTV survey methods and technology since 2002. Since then, survey coverage has been expanded: in 2014 the main Nephrops stocks fished in Irish waters are have all been fully surveyed – Aran Grounds, Porcupine Bank, Western Irish Sea, Eastern Irish Sea, South Coast, Smalls, Labadie, Jones and Cockburn Banks.

These UWTV surveys form the cornerstone of the ICES assessments and management advice. The results of the TV surveys directly form the basis of the catch options.

All UWTV Marine Institute surveys reports are available online in the Marine Institute's open access repository.

#CoastalNotes - The new Foreshore Bill is set to "radically change" Ireland's relationship with our coast, according to Coastwatch Ireland co-ordinator Karin Dubsky.

As The Irish Times reports, Dubsky was speaking at the launch of the 2014 Coastwatch Survey, welcoming the new bill that will see responsibilities for coastal management transferred to local authorities.

Previously, the Foreshore and Dumping at Sea (Amendment) Bill 2009 had transferred all foreshore licensing functions not associated with aquaculture and sea fishing from the then Department of Agriculture, Fisheries and Food to the erstwhile Department of the Environment, Heritage and Local Government.

Dubsky said the new legislation would give ordinary citizens a chance to shape Ireland's coastal policy via public audits such as the annual month-long Coastwatch Survey.

#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.

#Angling - Inland Fisheries Ireland (IFI) wants your help to improve fish habitats and make your angling experience better.

Anglers across Ireland are being invited to take part in a survey as part of an international report on anglers' habits and how they rate the fisheries they frequent.

"Great fishing is about the prospect of lots of quality fish while spending time enjoying the outdoors," says IFI. "Quality fish come from healthy populations enjoying good water, plenty of food and access to habitat.

"When we have dams, denuded riverbanks, culverts, dredged gravel beds and poor water quality we don’t have healthy fish and we certainly don’t have great fishing experiences."

The survey should take no more than five minutes to complete. All information collected is anonymous and not related to your email address.

IFI is also offering a prize draw liked at the end of the survey where you could win a €300 tackle voucher.

#MarineNotice - Marine Notice No 29 of 2014 calls on all ship managers, shipmasters, sailors, operators of fixed platforms and operators of non-SOLAS vessels to participate in the 2014 Marine Meteorological Monitoring Survey, which is available HERE.

The World Meteorological Organization (WMO) conducts the Marine Meteorological Monitoring Survey (MMMS) on a regular basis.

This is a tool to improve the level of meteorological support co-ordinated by the Joint WMO-IOC Technical Commission for Oceanography and Marine Meteorology (JCOMM), providing invaluable information to understand and reflect the needs and requirements of all marine communities in order to improve Marine Meteorological Information Services, as part of the Global Maritime Distress and Safety System (GMDSS).

The survey will continue until 30 June 2014. Any questions or enquiries should be made directly to the WMO Marine Meteorology and Oceanography Programme by email to [email protected] and not to the Department of Transport, Tourism and Sport.

#Angling - Inland Fisheries Ireland (IFI) is currently carrying out a complete fish stock survey on Lough Ree in the Midlands to assess the current status of coarse, pike and game fish populations in the lake.

The survey, which began on Monday 24 February and continues till Friday 14 March 2014, involves netting of 200 sites throughout Lough Ree performed by IFI staff from the Shannon River Basin Districts (ShRBD) and research staff in Swords, and comprising a total of five boat crews, two safety crews and processing crews based around Lough Ree.

The time of year of the survey is comparable with netting surveys on other major lakes in Ireland over the last 30 years or so. The type of information gleaned from the survey will include catch per unit effort (CPUE) for each fish species, size distributions of fish caught, aging for all species and microsatellite (DNA) analysis (for brown trout).

Sampling to assess the distribution of introduced (invasive) species will be carried out, with particular reference to the invasive ‘Asian clam’ Corbicula fluminea.

The genetic analysis of the brown trout will contribute the survey work carried out in 2013, with participation from anglers on Lough Ree, Lough Derravaragh, Lough Owel and the River Suck. In 2013 anglers sampled scales from adult trout caught in these areas and submitted these samples to IFI for DNA analysis.

In addition, all the major sub-catchments around Lough Ree, River Inny and River Suck were electro-fished in 2013 to help build up a baseline by which adult trout caught in these waterways can be attributed to the rivers in which they were spawned.

IFI describes this as very exciting work that will help build up a picture of what rivers (or parts of river sub-catchments) are contributing to the adult brown trout populations on these major lakes.

Similar work on the major western lakes have shown that the native brown trout can undertake extensive feeding and spawning migrations and has also shown (for example the ‘Croneen’ trout of the Camcor/Little Brosna system) that there are genetically distinct populations of trout which undergo large migrations from specific river systems to feed in large lakes like Lough Derg and Lough Ree.

Another aspect of this current netting survey will involve floy tagging of pike. Floy tags will be inserted below the dorsal fin of the pike and each fish will be released. Each tag will have a unique reference number which can easily be identified on later recapture of the pike.

Anglers will again be asked to record these tag numbers and potentially the length of fish, particularly during the major pike angling tournaments on Lough Ree in 2014. This will work as a mark-recapture method for estimating pike numbers in the lake, and it could potentially provide information on the growth rate of pike.

The survey crews will be very visible on Lough Ree over the next few weeks and all sets of nets will be marked with distinctive buoys labeled ‘IFI Survey’. Any anglers or other lake users are asked to be vigilant if out and about on the lake over the next few weeks and to avoid snagging in the nets.

#Angling - Almost one in every 10 people in Northern Ireland went fishing in the last 12 months - but 70% of NI residents said they had no interest in the sport.

These statistics were among the key findings in a new report on attitudes to angling by adults in Northern Ireland, using data from the Northern Ireland Omnibus Survey conducted this past April.

As the Belfast Telegraph reports, among the other findings were that almost a fifth of the population used to go fishing but no longer so do, while some 4% of the populace have never fished before and would like to try.

Most respondents cited their lack of interest in putting them off angling as a pastime, while 19% said they did not have enough free time.

But 12% said better information on how to fish would encourage them to take out a rod and reel.

For all you need on the Marine Environment - covering the latest news and updates on marine science and wildlife, weather and climate, power from the sea and Ireland's coastal regions and communities - the place to be is Afloat.ie.

Coastal Notes

The Coastal Notes category covers a broad range of stories, events and developments that have an impact on Ireland's coastal regions and communities, whose lives and livelihoods are directly linked with the sea and Ireland's coastal waters.

Topics covered in Coastal Notes can be as varied as the rare finding of sea-life creatures, an historic shipwreck with secrets to tell, or even a trawler's net caught hauling much more than just fish.

Other angles focusing the attention of Coastal Notes are Ireland's maritime museums, which are of national importance to maintaining access and knowledge of our nautical heritage, and those who harvest the sea using small boats based in harbours where infrastructure and safety pose an issue, plying their trade along the rugged wild western seaboard.

Coastal Notes tells the stories that are arguably as varied as the environment they come from, and which shape people's interaction with the natural world and our relationship with the sea.

Marine Wildlife

One of the greatest memories of any day spent boating around the Irish coast is an encounter with Marine Wildlife. It's a thrill for young and old to witness seabirds, seals, dolphins and whales right there in their own habitat. And as boaters fortunate enough to have experienced it will testify, even spotting a distant dorsal fin can be the highlight of any day afloat. Was that a porpoise? Was it a whale? No matter how brief the glimpse, it's a privilege to share the seas with Irish marine wildlife.

Thanks to our location in the North Atlantic, there appears to be no shortage of marine life to observe. From whales to dolphins, seals, sharks and other ocean animals, the Marine Wildlife category documents the most interesting accounts around our shores. And we're keen to receive your observations, your photos, links and video clips, too!

Also valuable is the unique perspective of all those who go afloat, from coastal sailing to sea angling to inshore kayaking to offshore yacht racing, as what they encounter can be of great importance to organisations such as the Irish Whale and Dolphin Group (IWDG). Thanks to their work we now know we share the seas with dozens of species who also call Ireland home. But as impressive as the list is, the experts believe there are still gaps in our knowledge. Next time you are out on the ocean waves, keep a sharp look out!

Weather

As an island in the North Atlantic, Ireland's fate is decided by Weather more so than many other European countries. When storm-force winds race across the Irish Sea, ferry and shipping services are cut off, disrupting our economy. When swollen waves crash on our shores, communities are flooded and fishermen brace for impact - both to their vessels and to their livelihoods.

Keeping abreast of the weather, therefore, is as important to leisure cruisers and fishing crews alike - for whom a small craft warning can mean the difference between life and death - as it is to the communities lining the coast, where timely weather alerts can help protect homes and lives.

Weather affects us all, and Afloat.ie will keep you informed on the hows and the whys.

Marine Science

Perhaps it's the work of the Irish research vessels RV Celtic Explorer and RV Celtic Voyager out in the Atlantic Ocean that best highlights the essential nature of Marine Science for the future growth of Ireland's emerging 'blue economy'.

From marine research to development and sustainable management, Ireland is developing a strong and well-deserved reputation as an emerging centre of excellence. Whether it's Wavebob ocean energy technology to aquaculture to weather buoys and oil exploration, the Marine Science category documents the work of Irish marine scientists and researchers and how they have secured prominent roles in many European and international marine science bodies.

Power From The Sea

The message from the experts is clear: offshore wind and wave energy is the future. And as Ireland looks towards the potential of the renewable energy sector, generating Power From The Sea will become a greater priority in the State's 'blue growth' strategy.

Developments and activities in existing and planned projects in the pipeline from the wind and wave renewables sector, and those of the energy exploration industry, point to the future of energy requirements for the whole world, not just in Ireland. And that's not to mention the supplementary industries that sea power projects can support in coastal communities.

Irish ports are already in a good position to capitalise on investments in offshore renewable energy services. And Power From The Sea can even be good for marine wildlife if done properly.

Aside from the green sector, our coastal waters also hold a wealth of oil and gas resources that numerous prospectors are hoping to exploit, even if people in coastal and island areas are as yet unsure of the potential benefits or pitfalls for their communities.

Changing Ocean Climate

Our ocean and climate are inextricably linked - the ocean plays a crucial role in the global climate system in a number of ways. These include absorbing excess heat from the atmosphere and absorbing 30 per cent of the carbon dioxide added to the atmosphere by human activity. But our marine ecosystems are coming under increasing pressure due to climate change.

The Marine Institute, with its national and international partners, works to observe and understand how our ocean is changing and analyses, models and projects the impacts of our changing oceans. Advice and forecasting projections of our changing oceans and climate are essential to create effective policies and management decisions to safeguard our ocean.

Dr Paul Connolly, CEO of the Marine Institute, said, “Our ocean is fundamental to life on earth and affects so many facets of our everyday activities. One of the greatest challenges we face as a society is that of our changing climate. The strong international collaborations that the Marine Institute has built up over decades facilitates a shared focusing on our changing ocean climate and developing new and enhanced ways of monitoring it and tracking changes over time.

“Our knowledge and services help us to observe these patterns of change and identify the steps to safeguard our marine ecosystems for future generations.”

The Marine Institute’s annual ocean climate research survey, which has been running since 2004, facilitates long term monitoring of the deep water environment to the west of Ireland. This repeat survey, which takes place on board RV Celtic Explorer, enables scientists to establish baseline oceanic conditions in Irish waters that can be used as a benchmark for future changes.

Scientists collect data on temperature, salinity, water currents, oxygen and carbon dioxide in the Atlantic Ocean. This high quality oceanographic data contributes to the Atlantic Ocean Observing System. Physical oceanographic data from the survey is submitted to the International Council for the Exploration of the Seas (ICES) and, in addition, the survey contributes to national research such as the VOCAB ocean acidification and biogeochemistry project, the ‘Clean Atlantic’ project on marine litter and the A4 marine climate change project.

Dr Caroline Cusack, who co-ordinates scientific activities on board the RV Celtic Explorer for the annual survey, said, “The generation of long-term series to monitor ocean climate is vital to allow us understand the likely impact of future changes in ocean climate on ecosystems and other marine resources.”

Other activities during the survey in 2019 included the deployment of oceanographic gliders, two Argo floats (Ireland’s contribution to EuroArgo) and four surface drifters (Interreg Atlantic Area Clean Atlantic project). The new Argo floats have the capacity to measure dissolved ocean and biogeochemical parameters from the ocean surface down to a depth of 2,000 metres continuously for up to four years, providing important information as to the health of our oceans.

During the 2019 survey, the RV Celtic Explorer retrieved a string of oceanographic sensors from the deep ocean at an adjacent subsurface moored station and deployed a replacement M6 weather buoy, as part of the Irish Marine Data Buoy Observation Network (IMDBON).

Funded by the Department of Agriculture, Food and the Marine, the IMDBON is managed by the Marine Institute in collaboration with Met Éireann and is designed to improve weather forecasts and safety at sea around Ireland. The data buoys have instruments which collect weather and ocean data including wind speed and direction, pressure, air and sea surface temperature and wave statistics. This data provides vital information for weather forecasts, shipping bulletins, gale and swell warnings as well as data for general public information and research.

“It is only in the last 20 years, meteorologists and climatologists have really began to understood the pivotal role the ocean plays in determining our climate and weather,” said Evelyn Cusack, Head of Forecasting at Met Éireann. “The real-time information provided by the Irish data buoy network is particularly important for our mariners and rescue services. The M6 data buoy in the Atlantic provides vital information on swell waves generated by Atlantic storms. Even though the weather and winds may be calm around our shores, there could be some very high swells coming in from Atlantic storms.”
