PhD student Catherine Jordan will bring her research on phytoplankton blooms to the third annual Soapbox Science even in Galway tomorrow afternoon (Saturday 29 June).

She will be among 12 female scientists standing on their soapboxes to talk about their groundbreaking research in the areas of science, technology, engineering, mathematics and medicine at the city’s Spanish Arch from noon to 3pm.

Jordan, a PhD candidate through the Marine Institute’s Cullen Fellowship Programme and NUI Galway, will discuss her research on using satellite technology to observe and identify phytoplankton blooms in North-East Atlantic waters.

“When conditions are right, phytoplankton appear in high numbers and produce green and dark red hues in the water and are known as ‘algal blooms’,” she explains.

“As these blooms can sometimes be visible from space, satellites provide a useful tool in monitoring the location and extent of these blooms.

“In most cases phytoplankton blooms are of benefit to the ecosystem, but a small proportion of phytoplankton species produce toxins which may affect other marine life.

“Satellites may be able to assist in providing early wide-scale warnings of the presence of algal blooms, by using ocean colour sensors. A lot of my research focuses on measuring optical properties of light by using different instruments and methods, as well as validating satellite measurements.”

Jordan recently joined the Marine Institute’s annual ocean climate research survey on the RV Celtic Explorer to collect plankton samples and hyperspectral radiometer data as part of her PhD research.

Speaking about the Soapbox Science even, Jordan said: “I am very passionate about my field of science and also promoting how women can work on marine research vessels and spend weeks at sea.

“It is very important to engage the public in learning about marine science in interactive ways in order to explain very complex matters. Soapbox Science is an excellent platform for promoting women in science and encouraging the public to discuss topics they may not have encountered before.”

Soapbox Science Galway began two years ago, and talks this year will cover a diverse range of topics such as enhancing farming using insects, the marvels of human milk, the internet as a force for good, and statistical thinking for real-life questions.

The event will also be held in Dublin and Cork, as well as in several countries around the world including the UK, US, Canada, Australia, Sweden, Germany, Brazil and South Africa.

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.
