Scientific applications of marine data communication

Scientific applications of marine data communication

Belfield campus.
I was privileged today to deliver a short lecture to the students of Professor Dias in UCD. It was totally unprepared and probably I should not use the term lecture as presentation is probably more appropriate. The term presentation has a commercial connotation which was not intended in this case  . Beside, when a presentation is designed to educate, then it is a lecture in its own right. Belfield campus in Dublin is far from my dear Naval College in Cork, where a new Marine ICT lab is taking shape in preparation for next semester. When I say far I do not mean geographically far. I am used to speak to engineers but mathematicians are just as keen with technology. I could definitely get addicted to their curiosity. 


Scientists are consuming data like never before, the IoT revolution is promising enough data to help finding solutions to environmental issues that will eventually cause the extinction of our civilisation. Telecommunications are probably not up to the job and there is still a lot to be done to be able to deliver realtime data to scientists especially with ocean data.


Scientific applications of marine data communication is a vast topic, it was very ambitious of us to propose this discussion as an introduction to Instant Wave a project lead by Professor Dias for two years. Meteorologists are using mathematical forecast models to predict weather such as Numerical weather prediction (NWP). When it comes to rogue waves, there is no such thing, waves are observed, recorded, analysed. Crushing realtime numbers would help setting algorithms to predict the formation of environmental disasters if only proper marine coms were available. I remember reading an excellent paper on fast Fourier transform applied to estimate wave energy spectral density in random sea state (1). The real issue of wave realtime observation is data communications. Satellite communications are too expensive and cellular not available where it matters most from a wave observation perspective. The challenges of realtime marine data were discussed for over two hours followed by a well attended Q&A session... 


Looking into different case study (available on this website) we discussed about the different applications where marine data communications could pump data into algorithmic complex forecasting. For the past couple of years SEA-Tech has been funding the design of an open source realtime data capture platform until we get more substantial funding to deploy a real platform. Each year, students are contributing to the development of a cost effective data buoy. There names are Lorena, Isidoro, Robin, Jean Baptiste... they are contributing to world change...


I have always been a firm believer that education helps changing people and eventually impact the future through collective intelligence. By giving a bit of time today, I have made sure that a handful of researchers will consider alternative technology in their professional future instead of using commercial fame and public knowledge.

Merci Frederic...
