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.

The Half Ton Class was created by the Offshore Racing Council for boats within the racing band not exceeding 22'-0". The ORC decided that the rule should "....permit the development of seaworthy offshore racing yachts...The Council will endeavour to protect the majority of the existing IOR fleet from rapid obsolescence caused by ....developments which produce increased performance without corresponding changes in ratings..."

When first introduced the IOR rule was perfectly adequate for rating boats in existence at that time. However yacht designers naturally examined the rule to seize upon any advantage they could find, the most noticeable of which has been a reduction in displacement and a return to fractional rigs.

After 1993, when the IOR Mk.III rule reached it termination due to lack of people building new boats, the rule was replaced by the CHS (Channel) Handicap system which in turn developed into the IRC system now used.

The IRC handicap system operates by a secret formula which tries to develop boats which are 'Cruising type' of relatively heavy boats with good internal accommodation. It tends to penalise boats with excessive stability or excessive sail area.

Competitions

The most significant events for the Half Ton Class has been the annual Half Ton Cup which was sailed under the IOR rules until 1993. More recently this has been replaced with the Half Ton Classics Cup. The venue of the event moved from continent to continent with over-representation on French or British ports. In later years the event is held biennially. Initially, it was proposed to hold events in Ireland, Britain and France by rotation. However, it was the Belgians who took the ball and ran with it. The Class is now managed from Belgium.
