#MarineScience - Over 300 Transition Year students from Galway and further afield visited the Marine Institute yesterday (Thursday 20 November) as part of the Galway Science & Technology Festival.

The students met scientists and staff, discovered the wide ranging work of the Marine Institute and got a glimpse of what it would be like to work in marine research.

“We’re delighted to open our doors to students today and we hope they’ll be inspired by the people they meet here and by the work that we’re doing to understand our unique ocean resources," said Marine Institute chief executive Dr Peter Heffernan.

"Some of the students may even go on to become ocean explorers as marine biologists, oceanographers, geographers, mapping the seabed or as engineers, developing novel marine renewable energy devices."

Dr Heffernan also hailed the "many opportunities, particularly with a national and EU focus on the potential of the ‘blue economy’ with the Government plan Harnessing Our Ocean Wealth and the European Commission’s Atlantic Strategy.”

The visit included a talk by Helen McCormick of the Fisheries Ecosystem Advisory Services on the work of the Marine Institute, a 'Sea for Society' video showing the importance of our ocean resource, and an exhibition on marine careers and training opportunities, including the institute's own annual bursar programme for third level students.

Staff and scientists demonstrated their work using touchscreen interactive seabed maps, fish samples and even a mini submarine. They answered well thought-out questions on their work in fisheries science, seabed mapping, seafood safety, oceanography, ocean chemistry and research vessel operations.

#Fishing - Illegal fishing may have just got a little more difficult thanks to a new marine science project backed by Google that aims to map commercial fishing activity around the globe in near real time.

According to The Verge, the Global Fishing Watch system – launched at the IUCN World Parks Congress in Sydney, Australia last week – uses satellite mapping data from SpaceQuest plugged into specialised software from SkyTruth that allows users to track the activity of thousands of fishing boats across the world's oceans.

Wired goes into greater detail on the revolutionary system, which employs complex algorithms to find the most likely patterns of behaviour, from movement to radio usage, that identify a boat as being engaged in fishing.

Using data from 2012 to 2013, the system filtered billions of AIS radio messages sent by over 100,000 ocean-going vessels down to some 25,000 boats that bore the strongest signs of fishing activity - and determined that over 3,000 of those were indeed fishing vessels.

Marine conservation group Oceana, which has led the Global Fishing Watch initiative, says that once the system is ready to handle live data, it will be able to track fishing fleets and individual ships to within a few days – allowing for law enforcement to act if potentially harmful activity is detected.

And the public at large will be able to view the maps in their web browsers, and contribute towards identifying the most likely culprits of illegal fishing.

Wired has much more on the story HERE.

#Fishing - The Marine Institute intends to obtain samples of spawning herring at the Bills of Achill this month, and the Glen Head/Aranmore area in December.

The samples will be taken during spawning time. These samples are urgently required to assess the extent of mixing of Irish-spawned herring in VIa, particularly VIaN (West of Scotland).

They will be used in a discriminant analysis of herring caught during the summer acoustic survey, taking place West of Scotland and Ireland. The analysis is a matter of urgency because the stocks are subject to a new ICES assessment in 2015.

Currently, herring in VIaN are considered to be part of a separate stock. However preliminary analysis by the Marine Institute suggests a component of herring in VIaN in summer belong to the NW Irish stock.

Authorisation has been received to allow two pairs of pelagic RSW vessels to enter the 12-mile territorial limits, and to fish herring on these known spawning grounds, on one occasion off Mayo and one off Donegal.

The vessels are the FV Olgarry and FV Pacelli, and the FV Felucca and FV Genesis II. These vessels will be fishing against their existing NW herring quotas, and are not being awarded any additional scientific quota for the exercise.

#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.

#MarineScience - Seabed mapping activity and developments during 2014 will be showcased at the annual seminar of Ireland’s national marine mapping initiative, INFOMAR, was opened yesterday (Wednesday 22 October) at the Tower Hotel in Waterford.

The INFOMAR programme, dedicated to increasing awareness of Ireland’s marine landscape, carries out hydrographic and geophysical surveys of Irish territorial waters.

It is a co-operative research programme between the Geological Survey of Ireland (GSI) and the Marine Institute (MI) and is funded by the Department of Communications, Energy and Natural Resources.

This ambitious mapping initiative began in 2006, and in its first 10 years will successfully map 26 priority bays and three priority offshore areas.

Using INFOMAR resources, skilled experts based at the GSI and MI develop data products, primarily hydrographic and geological maps that detail the Irish marine territory. These maps are now available for scrutiny HERE.

Minister of State Joe McHugh TD, who was present at the opening, said: “The Government has been strongly supportive of this project, committing €15 million for the five-year period from 2014 to 2018.

"With this continued funding support, Ireland is at the leading edge of European work in marine mapping and in laying the foundations for the sustainable management of our ocean space."

The minster added that “this year a further €3 million is being invested under the INFOMAR project in surveying the gateways to our ports, mapping our fish spawning grounds, finding routes for marine telecommunications cables and selecting the best sites for ocean energy generation. All rely on accurate seabed mapping capability, which Ireland now possesses.”

The 2014 INFOMAR annual seminar will provide an update on progress and plans, and focus on the downstream value and application of the data to underpin development and growth across the marine sector.

New INFOMAR products and services are continuously evolving, and the event will see the launch of a new education programme, a prototype dive tourism mobile app, and INFOMAR Story Maps.

Welcoming the launch, GSI director Koen Verbruggen said that the long-term benefits to Ireland as a result of INFOMAR’s offshore mapping are significant, and include:

  • Datasets that feed directly into updated nautical charts via the United Kingdom Hydroghaphic Office.
  • Up-to-date advanced mapping facilitates greater awareness of Irish marine opportunities.
  • The data are used in planning of protection and development offshore Ireland.
  • This project is also highlighting data and knowledge gaps for further exploration and research.
  • New international research links have been forged between the surveys and agencies, which is resulting in related projects and employment.

Dr Peter Heffernan, chief executive of the Marine Institute, said: "The Government has prioritised the marine as an area for further growth under the Harnessing Our Ocean Wealth Strategy and the information on Ireland’s vast seabed territory that INFOMAR is capturing and making available will provide a solid platform for sustainable development and growth."

Over 130 attendees are expected to attend the over the day-and-a-half seminar. The work of INFOMAR is also showcased in the latest episode of TV3's maritime documentary series Our Island, broadcast last night and which will be available to stream via the TV3 Player.

#MarineScience - George Hanna, a student of the Benthic Acoustic Mapping and Survey (BEAMS) programme in the USA, recently joined the Irish INFOMAR team on the research vessel RV Celtic Voyager during an inshore survey of Mizen Head, Co Cork.

The INFOMAR team provided fieldwork training on board the RV Celtic Voyager using the newly installed EM2040 state-of-the-art multibeam technology to develop detailed maps of the seafloor, as well as a sub-bottom profiler to identify and characterise layers of sediment and rock and surrounding habitat.

Training support is hugely beneficial in developing academic and career opportunities in bathymetric and seafloor habitat mapping on both sides of the Atlantic.

“With the rapid growth of new technologies used in ocean surveying, it is important that undergraduate students get fieldwork experience which focuses on strengthening their skills that can be used in the workforce,” said Thomas Furey, manager of Advanced Mapping Services at the Marine Institute and joint INFOMAR programme manager with the Geological Survey of Ireland.

Collaboration with the College of Charleston and University of Washington’s BEAMS programme came about after focussed development of international INFOMAR industry and research relations in recent years.

This was instigated following the transatlantic co-operation agreement, the 'Galway Statement', signed at the Marine Institute in 2013.

INFOMAR, which hosts its annual seminar in Waterford next week, also supported the nomination of Jay Calvert, University of Ulster, who was recently awarded a Fulbright-Marine Institute Scholarship to attend three months each at Alaska Pacific University in Anchorage, and Northeastern University in Boston.

The BEAMS programme is widely recognised internationally for the output of many academically qualified ocean surveyors, however gaining vessel experience can be challenging. 

Volunteering as a survey technician through the programme, George Hanna highlighted the benefits of working with INFOMAR onboard the RV Celtic Voyager, stating: “I was extremely lucky to come to Ireland to get hands on experience on the Voyager and to work with some of the best sonar technology equipment out there.

"Getting real experience during survey operations and deploying numerous ocean-survey related instruments certainly helps support me in expanding my academic opportunities and also getting future work in the area of seabed mapping”.

Dublin Bay

Dublin Bay on the east coast of Ireland stretches over seven kilometres, from Howth Head on its northern tip to Dalkey Island in the south. It's a place most Dubliners simply take for granted, and one of the capital's least visited places. But there's more going on out there than you'd imagine.

The biggest boating centre is at Dun Laoghaire Harbour on the Bay's south shore that is home to over 1,500 pleasure craft, four waterfront yacht clubs and Ireland's largest marina.

The bay is rather shallow with many sandbanks and rocky outcrops, and was notorious in the past for shipwrecks, especially when the wind was from the east. Until modern times, many ships and their passengers were lost along the treacherous coastline from Howth to Dun Laoghaire, less than a kilometre from shore.

The Bay is a C-shaped inlet of the Irish Sea and is about 10 kilometres wide along its north-south base, and 7 km in length to its apex at the centre of the city of Dublin; stretching from Howth Head in the north to Dalkey Point in the south. North Bull Island is situated in the northwest part of the bay, where one of two major inshore sandbanks lie, and features a 5 km long sandy beach, Dollymount Strand, fronting an internationally recognised wildfowl reserve. Many of the rivers of Dublin reach the Irish Sea at Dublin Bay: the River Liffey, with the River Dodder flow received less than 1 km inland, River Tolka, and various smaller rivers and streams.

Dublin Bay FAQs

There are approximately ten beaches and bathing spots around Dublin Bay: Dollymount Strand; Forty Foot Bathing Place; Half Moon bathing spot; Merrion Strand; Bull Wall; Sandycove Beach; Sandymount Strand; Seapoint; Shelley Banks; Sutton, Burrow Beach

There are slipways on the north side of Dublin Bay at Clontarf, Sutton and on the southside at Dun Laoghaire Harbour, and in Dalkey at Coliemore and Bulloch Harbours.

Dublin Bay is administered by a number of Government Departments, three local authorities and several statutory agencies. Dublin Port Company is in charge of navigation on the Bay.

Dublin Bay is approximately 70 sq kilometres or 7,000 hectares. The Bay is about 10 kilometres wide along its north-south base, and seven km in length east-west to its peak at the centre of the city of Dublin; stretching from Howth Head in the north to Dalkey Point in the south.

Dun Laoghaire Harbour on the southside of the Bay has an East and West Pier, each one kilometre long; this is one of the largest human-made harbours in the world. There also piers or walls at the entrance to the River Liffey at Dublin city known as the Great North and South Walls. Other harbours on the Bay include Bulloch Harbour and Coliemore Harbours both at Dalkey.

There are two marinas on Dublin Bay. Ireland's largest marina with over 800 berths is on the southern shore at Dun Laoghaire Harbour. The other is at Poolbeg Yacht and Boat Club on the River Liffey close to Dublin City.

Car and passenger Ferries operate from Dublin Port to the UK, Isle of Man and France. A passenger ferry operates from Dun Laoghaire Harbour to Howth as well as providing tourist voyages around the bay.

Dublin Bay has two Islands. Bull Island at Clontarf and Dalkey Island on the southern shore of the Bay.

The River Liffey flows through Dublin city and into the Bay. Its tributaries include the River Dodder, the River Poddle and the River Camac.

Dollymount, Burrow and Seapoint beaches

Approximately 1,500 boats from small dinghies to motorboats to ocean-going yachts. The vast majority, over 1,000, are moored at Dun Laoghaire Harbour which is Ireland's boating capital.

In 1981, UNESCO recognised the importance of Dublin Bay by designating North Bull Island as a Biosphere because of its rare and internationally important habitats and species of wildlife. To support sustainable development, UNESCO’s concept of a Biosphere has evolved to include not just areas of ecological value but also the areas around them and the communities that live and work within these areas. There have since been additional international and national designations, covering much of Dublin Bay, to ensure the protection of its water quality and biodiversity. To fulfil these broader management aims for the ecosystem, the Biosphere was expanded in 2015. The Biosphere now covers Dublin Bay, reflecting its significant environmental, economic, cultural and tourism importance, and extends to over 300km² to include the bay, the shore and nearby residential areas.

On the Southside at Dun Laoghaire, there is the National Yacht Club, Royal St. George Yacht Club, Royal Irish Yacht Club and Dun Laoghaire Motor Yacht Club as well as Dublin Bay Sailing Club. In the city centre, there is Poolbeg Yacht and Boat Club. On the Northside of Dublin, there is Clontarf Yacht and Boat Club and Sutton Dinghy Club. While not on Dublin Bay, Howth Yacht Club is the major north Dublin Sailing centre.
