#lusitania – Minister of State with responsibility for Natural Resources at the Department of Communications, Energy & Natural Resources, Joe McHugh T.D., and Minister for Arts, Heritage and the Gaeltacht, Heather Humphreys T.D, today welcomed the publication of new state-of-the-art sonar imagery of the RMS Lusitania. Members of the INFOMAR (INtegrated Mapping FOr the Sustainable Development of Ireland's MARine Resource) team from the Geological Survey of Ireland (GSI) and the National Monuments Service of the Department of Arts, Heritage and the Gaeltacht have recently produced and assessed this brand new sonar imagery of the wreck of the RMS Lusitania.

The current condition of the RMS Lusitania on the seafloor, 100-years after its sinking on May 7th 1915, is revealed in greater detail than ever before. The imagery provides a sense of the scale and history of the site, a tangible connection to the wreck and to the dramatic and tragic events that surrounded its sinking. The 240m long vessel is clearly defined on the sea floor, lying on its starboard side and standing over 14m high above the seabed.

Minister McHugh said that "The new imagery of the Lusitania provides the most detailed information and overview of the wreck site compiled to date and provides a solid framework upon which new research and analysis can be based".

Minister for Arts, Heritage and the Gaeltacht, Ms Humphreys, added "It is fitting that these images are being in the centenary year of the sinking of the Lusitania. The imagery will provide important information on how the shipwreck has changed over the last 100 years."

This new survey data is extremely important from a site protection point of view. It will add to our knowledge and understanding of the wreck site on the seabed, its current condition and how the site has changed or degraded over the years. Additionally, the data, in tandem with previous information from individual divers to the site, will be very beneficial in developing our understanding of the physical processes at play at the wreck site and in the surrounding seabed and should help inform long term management strategies for protecting, investigating and conserving the wreck .

One hundred years on, the Lusitania is beginning to reveal its wounds, scars and perhaps its secrets, and may continue to do so for many years to come.

#MarineScience - A subsea cable laid from the RV Celtic Explorer in Galway Bay this week marks a major milestone in the development of Ireland's national marine research and development infrastructure.

The four-kilometre cable and a frame to which sensors and monitoring equipment will be attached are part of the development of an ocean observatory in Galway Bay connecting the Galway Bay Ocean Energy Test Site to the shore at Spiddal, Co Galway.

The cable will supply power to the site and allow unlimited data transfer from the site for researchers testing innovative marine technology including renewable ocean energy devices.

The Marine Institute and the Sustainable Energy Authority of Ireland (SEAI) have been working together to promote and develop Ireland's ocean energy potential, and this project – with partners SmartBay Ltd, UCC (MarEI - Marine Renewable Energy Ireland), and Dublin City University – is part of a programme to enhance the Galway Bay Ocean Energy Test Site.

A suite of sensors and environmental monitoring equipment will be installed on the cable end frame this summer, as well a floating 'sea station' which will give developers real-time data on how their devices are performing in the ocean.

"Ireland's sea area is around 10 times the size of our land area and with one of the best offshore renewable energy resources in the world, the opportunities to harness the power of the ocean are immense," says Marine Minister Simon Coveney.

"The new facilities at the Galway Bay Ocean Energy Test site will attract companies and researchers developing marine technology and renewable ocean energy equipment, and will position Ireland at the forefront of these emerging sectors by developing an expert indigenous supply chain that will expand as these sectors grow.

"The ocean observatory will also enhance our ability to monitor the ocean and better understand how it works, which is critical to tackling issues such as climate change."

Energy Minister Alex White adds that "offshore renewable energy has the potential to be a major component of Ireland's future energy mix and it is vital that we facilitate developments like this one in Galway Bay.

"Over time, the introduction of ocean energy into Ireland's renewables portfolio will enhance the security of Ireland's energy supply, deliver green growth, and add to the 47,000 jobs already supported by our energy sector.

"Government support for ocean research, development and demonstration has been increasing with €16.8 million added to my department's multi-annual ocean energy development budget between 2013 and 2016, bringing the total cumulative funding to over €26 million."

Instrument nodes and sensor packages to be installed at the Galway Bay Ocean Energy Test Site this summer will contribute to marine sectors including environmental monitoring, shipping, maritime security and education.

Extensive historical wave and weather data is also available for this site since 2008 and is available to potential device developers.

The new research infrastructure is expected to position Galway Bay as a unique world-class ocean energy test site.

The addition of a cabled ocean observatory means Ireland will also play an important role in the Atlantic Ocean Research Alliance between Europe, the USA and Canada under the Galway Statement signed at the Marine Institute Galway in May 2013 – and under which the RV Celtic Explorer will undertake the first transatlantic mapping survey between Galway and Newfoundland this coming June.

The cable project is funded in part by Science Foundation Ireland (SFI) under its Research Infrastructure Call 2012 which contributed €2.2m to the project. The Department of Agriculture, Food and the Marine contributed an additional €600,000 to the project in 2014. The Department of Communications, Energy and Natural Resources will fund additional infrastructure and the ongoing operations of the Galway Bay test site through the SEAI Ocean Energy Programme.


More information on the project will be available at www.marine.ie and www.oceanenergyireland.com.

#mapping – The Minister for Agriculture, Food and the Marine, Simon Coveney TD today joined with Carlos Moedas, European Commissioner for Research, Science and Innovation, and Karmenu Vella, Commissioner for Environment, Maritime Affairs and Fisheries in Brussels, along with Canada's Minister of Fisheries and Oceans Gail Shea, to announce the first trans-Atlantic mapping survey to take place under the Atlantic Ocean Research Alliance.

The Irish research vessel, RV Celtic Explorer will undertake a mapping expedition between St. John's, Newfoundland, Canada and Galway in Ireland in June of this year, as scientists from the Marine Institute, Ireland will be joined by a multi-national team made up of USA, Canadian and European ocean mapping experts. This is an important step following the agreement reached at Galway in May 2013 and is an example of scientific diplomacy in action.

Speaking from Brussels, Minister Coveney said "Information from the sea-floor is vital to the sustainable management of the Atlantic as well as to important industries such as fisheries, aquaculture and tourism. Ireland has developed a world-leading reputation for sea-bed mapping and is also very committed to the implementation of the Galway Statement and so I am delighted to put at the disposal of the team, Ireland' state-of the art research vessel-RV Celtic Explorer."

Commissioner Moedas stated "I am committed to harnessing the societal and economic value of our oceans, while protecting fragile marine ecosystems. Under Horizon 2020 we have invested just under €70 million to support the Galway Statement follow-up. The first calls delivered excellent project proposals involving international teams. I am glad that this investment is being leveraged to make our transatlantic vision a reality."

Commissioner Vella welcomed the announcement, stating. "One of the priorities of my mandate is Ocean Governance. Our wish is that the EU continues to be fully engaged on this subject. The sea-bed mapping expedition announced today illustrates the EU's capacity as a global leader and partner. The 'Celtic Explorer's' mission across the north Atlantic will be undertaken by crew from 'both sides of the pond'. This embodies the spirit of cooperation that we need in the field of Ocean Governance. Their work will help inform the mapping of the European seabed, which is set to be completed by 2020. I congratulate all those involved".

Welcoming the initiative, the Honourable Gail Shea, Canada's Minister of Fisheries and Oceans said "Canada recognizes the importance and complexity of Atlantic Ocean science. Our nations' cooperation is key to broadening our scientific understanding of the Atlantic Ocean and helping to ensure it remains healthy, resilient and productive. This is why our scientists are collaborating through the Galway Statement to pool resources, share expertise and advance our science goals."

The announcement was made at the European Commission hosted event, 'The Atlantic- Our Shared resource. Making the Vision Reality' which was a follow up to the May 2013 signing of the Galway Statement on Atlantic Ocean Research Cooperation between the EU, Canada and the United States of America.

This event is the launch pad for all the Galway Statement follow-up projects funded with the first Horizon 2020 Blue Growth calls - the main financial instrument on the EU side implementing the Galway Statement commitments.

With a view to translating commitments into investments, the European Commission has earmarked around € 70 million in calls under Horizon 2020, the EU Research and Innovation Programme for the period 2014-2015.

Background:
The Galway Statement – The Atlantic Ocean Research Alliance
In May 2013, an Atlantic Ocean Research Alliance between Canada, the European Union and the United States of America was launched in Galway, Ireland, with the high level signature of the Galway Statement on Atlantic Ocean Cooperation.
The goals are to join forces to better understand the North Atlantic Ocean and to promote the sustainable management of its resources. Together we can build a capacity to understand and predict major Atlantic and Arctic processes, as well as the changes and risks they carry in relation to human activities and climate change.

The Galway Statement contributes to the implementation of the EU's Atlantic Strategy and its related Atlantic Action Plan. The Action Plan considers responses to the challenges of delivering growth, reducing the carbon footprint, using the sea's natural resources sustainably, responding effectively to threats and emergencies and implementing an "ecosystem" management approach in Atlantic waters.

The lead on the side of the Commission for the Ocean Research Alliance lies with DG RTD – the Directorate-General for Research and Innovation, in close coordination with DG MARE -the Directorate General for Maritime Affairs and Fisheries, which leads on the overall Atlantic Strategy.
Areas identified for cooperation under the agreement include:
· Ocean Stressors (e.g. ocean acidification)

· Aquaculture

· Interoperability and coordination of observing systems and infrastructures, including vessels

· Seabed and benthic habitat mapping

· Marine Microbial Ecology and

· Ocean Literacy

A series of regular Stakeholder Meetings to operationalise the Galway Statement started in Brussels in April and June 2014 with high level participation from Europe, US and Canada, bringing together a variety of existing networks already active on both sides of the Atlantic. Other Stakeholder Meetings were organised in 2014 in Washington D.C. and Ottawa. In December 2014 the first seabed mapping event took place in Dublin (Ireland), which was followed by another meeting in February 2015 in Brussels.

The Atlantic Ocean Research Alliance has been recognised as an example of how we can join efforts in research and innovation in the Joint Statement of the EU-US Summit on 26 March 2014, during President Obama's visit to Brussels. Also, the importance of this initiative was acknowledged in the EU-Canada Summit Declaration from September 2014, as a contribution to the strategic partnership in the field of research and innovation.
Since the signature of the Galway Statement, the expansion of this cooperation to the Southern part of the Atlantic, particularly towards Brazil and South Africa, has been evoked regularly. Brazilian and South African partners have been invited to several Atlantic Ocean Alliance events.

The event "The Atlantic – our Shared Resource: Making the Vision Reality" to launch research projects which constitute a clear follow-up of the Galway Statement and which were selected under the first Blue Growth call for proposals of Horizon 2020, takes place on 16-17 April 2015 in Brussels. Representatives from Brazil and South Africa are partners in some projects and will join representatives from Europe, the US and Canada in order to celebrate the translation of the political commitments taken in Galway into real investments which will boost the Atlantic Ocean Research Cooperation initiative.

#MarineWildlife - How do whales, dolphins and porpoises hunt for fish? By using 'sound searchlights', according to Danish marine researchers.

As BBC News reports, the team of marine scientists at Aarhus University used underwater microphones to study the hunting behaviour of porpoises.

And they sound that the nimble cetaceans were able to adjust their echolocation abilities – using clicks and buzzes to navigate their surroundings – by switching from a narrow focus to a wide beam of sound as they closed in on their prey.

Scientists believe that other species of dolphins and whales also share this "exceptional" ability – which could provide the key to solutions that would prevent them getting trapped in commercial fishing gear.

#MarineScience - Three Transition Year students recently completed placements hosted by INFOMAR at the Marine Institute.

Jack Lillis, Aoife Muldoon and Emily Egan learned how seabed mapping can improve safety at sea, how it relates to the fishing industry, and how it can help the development of sectors like ocean energy.

Each student spent a week visiting the various Marine Institute facilities and learning about the different activities of the institute.

At the end of their experience, each created a 'story map' and PowerPoint presentation to show what they achieved during their placements.

"We really enjoyed our week at the Marine Institute and we now know a lot more about what a career in marine science really means," said Muldoon and Egan, from St Brigid's Vocational School in Loughrea. "It's a hugely interesting area of science that we don't learn about in school.

"We especially enjoyed our visit to the Celtic Explorer, seeing the multibeam system, learning about seabed mapping and how this information improves the admiralty charts so that vessels like the Celtic Explorer can safely visit ports. We also learnt about how seabed mapping relates to the fishing industry and helps sectors like ccean energy, this was of particular interest to us.

"We would like to thank Vera and all the Advanced Mapping Services and Marine Institute staff for teaching us so much about seabed mapping, fisheries, the laboratories and how all the different areas interlink. We now have a much better idea of what subjects to pick for the Leaving Cert."

Lillis, of Gort Community School, also had "a fantastic week, all the areas I worked in were really enjoyable. I was particularly interested with the laboratory work. Everybody knew what they were talking about and nobody shied away from any questions in fact they encouraged them. Everybody had something lined up for me to do so I was kept really busy, which was great.

"Overall I really enjoyed my week in the Marine Institute and I'm a glad I chose it for my first week of work experience. It was both a good way to see a working environment but also has encouraged me to pursue a career in marine related chemistry. Thanks so much to Tommy, Vera, the Advanced Mapping Services team and staff at the Marine Institute for taking time out of their busy day to facilitate me."


The Marine Institute will run its Transition Year course placements on a pilot basis at the end of April for up to 20 students.

#MarineScience - Over 900 primary school students got to experience the wonders of the Irish marine environment at the Lifetime Lab in Cork where they participated in the Explorers Education Programme workshops from 2 to 13 March.

The pupils learned about marine animals and plants living in Irish waters. They also took part in water experiments involving water pressure, the power of the sea, making submarines and periscopes, as well as learning about the Real Map of Ireland, showing Ireland's marine territory and resources.

Lifetime Lab manager Mervyn Horgan said: "We are delighted to partner with the Marine Institute for the Explorers series of workshops, as we are always looking for new and innovative ways of engaging students in science education. Raising the awareness of marine science to Cork classrooms can only bring long-term benefits.

"We perceive the Lifetime Lab as an extra classroom for every school in the city and county, a science nursery for institutions whose high level graduates ensure that Cork has a well educated and highly skilled workforce long into the future."

Cushla Dromgool-Regan of the Marine Institite added that the Explorers programme "focuses on Ireland's two greatest resources – our young people and our vast marine territory.

"Inspiring students' interest in marine through the Explorers programme, teachers are able to easily include marine themed lessons based on the Irish curriculum already taught in national schools.

"Ireland is on its journey of realising the benefits of a thriving marine sector, and by engaging students interest in marine at a young age, we hope it will encourage them to consider some of the exciting wide range of careers in the marine - especially through some of Ireland's modern marine research centres around the country."

The Explorers Education Programme brings the excitement of the sea into the classroom and has already been successfully rolled out to some 12 schools in the greater Dublin and Wicklow area as well as reaching 90 primary schools in the West of Ireland in Mayo, Galway, Clare and Sligo during the 2014/15 school year. The Cork project is a collaborative effort between the Marine Institute, Galway Atlantaquaria and Lifetime Lab.

Further information and lesson plans are available at website at www.explorers.ie. For information about Explorers workshops, contact Lifetime Lab 021 494 1500 or www.lifetimelab.ie.

#warmlkake – A lake in county Mayo is among a number of lakes around the world that are 'warming' and Irish Marine Scientists are part of a global research project examining the trend. 

Data for Lough Feeagh, situated in the Burrishoole catchment in Co. Mayoforms part of the data, and is one of a small number of lakes worldwide for which long-term temperature data are available.

A temperature recorder on Lough Feeagh was originally installed in 1960, when the Salmon Research Trust of Ireland began investigations into the movement of salmon, trout and eel through the catchment. 

The magnitude and uniformity of the worldwide trend remains unclear but to facilitate research on this topic, a global database of summer temperatures for 291 lakes from 1859-2009 has been compiled, complemented by data on local climatic drivers and lake geomorphology.

The paper describing lakes as sentinels of climate change is published in the Journal of Scientific Data, by Nature (http://www.nature.com/sdata/) on the 17th March 2015. Dr Elvira de Eyto, Marine Institute and co author on the paper along with Marine Institute scientists are part of the Global Lake Temperature Collaboration (GLTC), an international group assembled to provide increased access to global lake temperature records.

The GLTC project recognised that a new global database of lake surface temperatures was needed, including not only satellite data, but also "on the ground" measurements from in situ data collection programs. Since its
inception in 2010, the GLTC initiative has grown to a database of 291 lakes and reservoirs worldwide, providing summer-mean lake surface temperatures from 1985-2009, and roughly doubling the amount of data previously available from satellites alone. This new dataset represents the first publicly available global compilation of in situ and satellite-based lake surface temperature data. The GLTC database also provides information on climatic drivers (air temperature, solar radiation, cloud cover), as well as geomorphometric characteristics that may affect lake temperature (latitude, longitude, elevation, lake surface area, maximum depth, mean depth, volume).
This unique, global dataset will offer an invaluable baseline perspective on lake thermal conditions for ongoing and future studies of environmental change. The Marine Institute continues this work, and maintains an extensive environmental monitoring programme in the catchment which is used to record climate and land use changes that may impact fish stocks.

#MarineScience - Inland Fisheries Ireland (IFI) and Queens University Belfast (QUB) jointly sealed a Memorandum of Understanding (MOU) at QUB’s Medical Biological Centre on Wednesday 11 March, expressing their commitment to a continued rich and productive liaison in research and education.

Over a number of years, scientists from QUB and IFI have worked in collaboration to produce high-quality research covering an extraordinary range of projects, species and topics. Current areas of joint research include fish population genetics, aquatic invasive species and fish telemetry. 

Speaking at the announcement, IFI’s head of research Dr Cathal Gallagher said: “IFI and QUB look forward to building on our existing relationship to produce the highest quality research outputs and publications to support the conservation and management on the inland fisheries resource.”

The organisations are also seeking to collaborate in encouraging and supporting the development of the next generation of fisheries scientists and technologists.

Dr Gallagher continued: “I am confident that the memorandum of understanding signed here today will act as an impetus to move forward with future research collaboration to support our shared goals. I see this collaboration as vital in supporting the development and education of the next generation of scientists into whose hands the future of this resource will be placed.


“I’m also extremely impressed by the expertise and quality of the joint research currently being undertaken and I look forward with anticipation to reviewing the outputs of these projects."

Prof Christine Maggs, head of the School of Biological Sciences at QUB also welcomed the announcement. “We are delighted that there is now formal recognition of the long and productive collaboration between QUB and IFI," she said.

“The school’s expertise in fish genetics, fish biology and aquatic ecology has been successfully applied to answering significant research questions for the IFI for more than a decade.”

#Fishing - The Marine Institute and Bord Iascaigh Mhara (BIM) convened an information meeting on the Aran Grounds Nephrops fishery and recent gear trials at the institute's headquarters in Oranmore this week.

The meeting on Tuesday 24 February was attended by more than 30 active skippers together with representatives from the IFPO, IS&WPO, IS&EPO and the KFO.

Marine Institute port-based and BIM gear technology personnel, as well as a Department of Agriculture, Food and Marine official were also in attendance.

Dr Paul Connolly, director of fisheries and ecosystem services at the Marine Institute, opened the meeting by saying that Nephrops (better known as Dublin Bay prawns or langoustines) are "a key resource for Irish fishermen, as over the last five years the value of the landings at first sale has doubled to almost €50m in 2014. Sustaining the stocks and the quota is a key management priority for the industry and the department."

He also noted that it was positive to see scientists and so many active fishermen discussing issues together.

The group heard presentations on the methodology and results of Marine Institute Nephrops Underwater Television Surveys (UWTV) on the Aran Grounds and other areas by Jennifer Doyle of the Marine Institute.

The latest ICES assessments and management advice for Nephrops on the Aran Grounds was also presented by Dr Colm Lordan from the Marine Institute, who chaired the discussions by the group.

Dr Lordan highlighted that "the assessments indicate that the stock size has declined to the lowest in the time series in 2014.

"Although fishing effort in terms of number of boat and days fished on the Aran Grounds shows no long-term trend since 1995, there has been an increase in both fishing power and efficiency with the increased uptake of quad rigs in the fishery".

According to Dr Lordan, a combination of high landings and reduced recruitment has resulted in harvest rates in 2012-2013 being twice that recommended by ICES.

He further advocated "national measures to reduce catches and effort in the short term in advance of the 2015 UWTV survey were required. This would demonstrate responsible management and give the best chance for increased stock size in June."

In response to this, Francis O'Donnell of the IFPO proposed that effort on vessels less than 20m would be limited to less than 20 days and effort for vessels larger than 20m would be limited to less than 10 days for the months of April and May. This was going to severely have an impact on some of his members, he said.

David Kirwan of the IS&EPO suggested that effort for all vessels be limited to less than 40 days for the three-month period April to June.

These proposals will be investigated by the Marine Institute to assess if they would be likely to deliver significant catch and effort reductions.

#MarineScience - The Atlantic Ocean: Our Unknown Treasure was on the agenda at the annual meeting of the American Association for the Advancement of Science (AAAS) in San Jose, California on Saturday 14 February.

Marine Institute chief executive Dr Peter Heffernan joined European Commission officials and leading scientists from the USA, Europe and Canada to discuss how to explore the largely unknown Atlantic Ocean; how new technologies can help us to challenge our understanding of the planet; and how new observation and visualisation tools can improve what we know about the seabed and inform science to help shape future marine policy.

The event built on the Galway Statement on Atlantic Ocean Research Co-operation signed at the Marine Institute in May 2013 by representatives from the EU, Canada and the US, launching an Atlantic Ocean Research Alliance.

Its goals are to better understand the Atlantic and the Arctic, to study the interplay between them, particularly relating to climate change, and to promote sustainable management of their resources.

Speaking about the event, Dr Heffernan said: "It's an exciting time, as all sides - European, US and Canadian - have shown engagement, planning and commitment to driving the Atlantic Ocean Research Alliance forward and preparing joint actions.

"There are very real global challenges to be tackled, and there is strong momentum now to create significant benefits such as better ecosystem assessments and forecasts and deeper understandings of vulnerabilities and risks.

"These transatlantic collaborations will also help to generate new tools to increase resilience and adaptation and to conserve our rich biodiversity. We also really need to foster public understanding of how ocean science and observation will address pressing issues for citizens and for the environment."

Dr Heffernan concluded: "The AAAS meeting gave an opportunity to see some of the collaborations that are undertaken in the Atlantic Ocean and discuss challenges for future research, technological developments, mapping and imaging as well as research co-operation across the Atlantic."

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.
