World Record Challenge

Do you remember the time of the dial-up internet? If you do, I bet you have this "Eeeee-aww-eeee-aww-eeee-aww-eeee-aww" sound in your head. And you think these days are long gone, with fibre optic and 4G available almost everywhere. However, this is really not the case once you leave the shore and set to the ocean. After a few nautical miles, cellular data becomes incidental and gradually using satellite communication is inevitable. A mostly unknown but large population of men and women are working at sea for eight to ten months of the year, only seeing their families on rare occasions. Consider also fishermen and all those who defend our coasts against the multiple kinds of trafficking, including any type of goods, and even human trafficking, and who are fighting to protect the marine ecosystem. And all they have in terms of communications are two possibilities: satellite, or cellular systems such as the 3G used by your mobile phone. SeaFi offers a new third option. SeaFi facilitates the creation of private networks in ports and coastal areas by establishing connections between lighthouses, maritime wind turbines, or offshore drilling platforms and vessels at sea. These networks are used to connect the ships and their crews, as well as the data collection buoys (weather, tides) for example. 

In 2018, using the SeaFi technology invented by Arnaud Disant, a scientific world record for the longest wireless internet communication at sea was established: 19.4 nautical miles (35.92 km). This year we are challenging this record. You might ask - why do you want to challenge your own record? Well, competing with yourself is the ultimate form of self-improvement and the one challenge that never ends. When we compete with ourselves, we focus on our own progress and growth, and we set our own standards of excellence. While striving to be better than we were yesterday, we push ourselves to new heights and achieve things we never thought possible. We have already been asked how to contribute to our effort. A fundraiser has been set up. Your contribution will go directly towards chartering the local cargo supply vessel that is essential to venture offshore beyond 19.4 nautical miles, thus making a positive impact on our community.

Online Short Seminars: Dan Giles on Tsunami Warning Tools

Online Short Seminars: Dan Giles on Tsunami Warning Tools

My first task as the newly elected Vice President of the SIAM-IMA Dublin area student chapter was to produce a short video detailing my research. My research focuses on the development of operational tools for tsunami warning centres. As this video was aimed at introducing my research to a wide audience, it simply provides a brief introduction. So if you would like to learn more about the fascinating dynamics of tsunamis and how warning centres try to mitigate their damages, please check out the quick 4 min video here:

Making this short video doubled as great practice for the Flash Talk series run by UCD's Earth Institute. This series was organised to mark the 50th anniversary of Earth Day.  I gave a quick 2 min talk detailing my research to a wide audience from across UCD and I was fortunate enough to win the audience prize! I would like to take this opportunity to thank all those involved in organising this event. It was a great way to see the huge scope of research which is carried out within the Earth Institute.

Finally, if you are undergraduate/postgraduate applied mathematician in the Dublin area and would like to get involved with the student chapter please check out our new website:
