#MarineScience - The Marine Institute and the Fulbright Commission are once again offering a unique opportunity for an Irish PhD candidate or scholar to travel to the USA to research in the fields of marine science or a marine-related business sector.

The Fulbright Commission is seeking applicants with academic and personal excellence, strong leadership potential and a commitment to being a Fulbrighter. The commission is particularly interested in receiving applications for this award from candidates who are exploring:

  • Marine Sensor Technologies and Observation Systems
  • Maritime Economics
  • Marine Spatial Planning
  • Maritime Law and Security
  • Renewable Ocean Energy
  • Marine Biotechnology (including Functional Foods)
  • Marine Environment
  • Oceanographic Modelling
  • Shipping
  • Seafood Safety
  • Ecosystems-based Fisheries Management
  • Big Data, and Sustainable Development

The 2018-2019 Fulbright Irish Awards supporting Irish and EU citizens to study, research or teach in the USA are now open for application. All applications are due by 4pm on Tuesday 31 October.

These globally-recognised and prestigious awards, operating between the United States and 155 countries, were founded by Senator J William Fulbright in 1946 “to expand the boundaries of human wisdom, empathy and perception” through educational and cultural exchange.

As a Fulbright Scholar, Dr Triona McGrath — a post-doctoral researcher at NUI Galway — visited Scripps Institution of Oceanography in San Diego in 2013 on a trip funded by the Marine Institute to develop her analytical skills in ocean carbon chemistry.

Dr McGrath has been researching ocean climate change since 2008 and highlights the value of her experience in the USA, saying: “The opportunity provided me with a wealth of information of how others work and increasing my knowledge at an international level.”

Dr McGrath’s team continues to monitor levels of carbon dioxide in Irish marine waters to determine the level of carbon in the ocean and subsequent increase in ocean acidity.

Along with her colleagues, Dr McGrath published the first rates of ocean acidification for Irish offshore waters and the first baseline dataset of carbon parameters in Irish coastal waters.

This data is crucial for our understanding of the future health of our oceans, and can provide information to determine the impacts of ocean acidification on marine ecosystems.

The Fulbright Commission in Ireland recently launched its new website and a promotional video called ‘Across the Water’ created by IADT student Gary Boyd, which also features Dr McGrath.

#MarineScience - A talk on how pollution is changing the chemistry of the seas around Ireland has been selected as a featured video by TED.com.

The talk by Irish marine scientist and Fulbright Scholar Dr Triona McGrath discusses the process of ocean acidification, caused by the absorption of carbon dioxide in the atmosphere into the world’s oceans.

A post-doctorate researcher at NUI Galway, Dr McGrath presented her talk on 6 February last year to a local audience at TEDxFulbrightDublin, organised by the Fulbright Commission in Ireland and Fulbright alumnus Dr Lorcan Walsh.

Dr McGrath’s team monitors levels of carbon dioxide in Irish marine waters to determine the level of carbon in the ocean and subsequent increase in ocean acidity.

Along with her colleagues, she published the first rates of ocean acidification for Irish offshore waters and the first baseline dataset of carbon parameters in Irish coastal waters.

This data is crucial for our understanding of the future health of our oceans, and can provide information to determine the impacts of ocean acidification on marine ecosystems.

In her talk, Dr McGrath states: “Ocean acidification is a global threat ... The rate of acidification is ten times faster than any acidification in our oceans for over 55 million years, our marine life has never experienced such a fast rate of change before ... There was a natural acidification event millions of years ago, it was much slower than what we're seeing today, this coincided with the mass extinction of many marine species.”

She also warns: “We will see acidification, we have already put too much carbon dioxide into the atmosphere ... but we can slow this down, we can prevent the worst case scenario. The only way of doing that is by reducing our carbon dioxide emissions.”

As a Fulbright Scholar, Dr McGrath visited the Scripps Institution of Oceanography in San Diego in 2013 to develop her analytical skills in ocean carbon chemistry.

A researcher in ocean climate change since 2008, her latest research project started in February 2017 and for the next four years she will work with colleagues to further develop ocean acidification research through the continuation of an ongoing time series in the Rockall Trough and the determination of seasonal and inter-annual variability of the carbon system in coastal waters.

Dr McGrath has a PhD in Chemical Oceanography and a BSc in Marine Science from NUI Galway.

About the TP52 Racing Yacht

The TP52 racing yacht is a remarkable example of cutting-edge technology in the world of competitive yachting. Measuring 52 feet (15.85 metres) in length, this vessel is constructed entirely from carbon fibre, making it an incredibly light and agile craft.

The TP52 features a 6.25-metre high rig, complete with a fractional asymmetrical spinnaker and a self-tacking jib. This design reduces the workload of the crew, allowing for more efficient manoeuvres and freeing up the crew to focus on the mainsheet upwind and on two-sail reaches.

The spinnaker rigging set-up, measuring 15.00 m2, presents a challenge to even the most experienced crews, requiring them to be fit and perfectly coordinated. Maneuvering the boat requires athleticism due to the vessel's lack of inherent stability and the high speed generated by the fully battened mainsail and jib.

The TP52's hull is constructed of fibreglass-reinforced polyester in a foam sandwich layout, resulting in a weight of just 74kg. The fully battened mainsail and jib are made from a transparent Mylar laminate with orange or red Dacron trimming, while the spinnaker is manufactured from ripstop Nylon.

The mast is made up of three parts, featuring an aluminium bottom and middle section, with a polyester-fibreglass composite tip to increase mast bend and decrease overall weight. The capsizing moment, which can be generated by a heavy mast tip, is also reduced through this design. The TP52's foils are constructed from either aluminium or fibreglass, depending on the specific requirements of the vessel.

Overall, the TP52 racing yacht is an exceptional example of the latest advancements in yacht design and technology. Its lightweight construction, advanced rigging, and high-speed capabilities make it a top contender in the world of competitive yachting, challenging even the most skilled and experienced crews.
