https://bigthink.com/the-present/ocean-rescue-traps/Researchers at MIT, the Swiss Federal Institute of Technology (ETH), the Woods Hole Oceanographic Institution (WHOI), and Virginia Tech recently announced the first successful trials of their new TRAPS system, a system they hope will provide faster, more accurate insights into the floating locations of missing objects and people by identifying the watery traps into which theyre likely to be attracted. The teams TRAPS research is published in the journal Nature Communications.
According to Thomas Peacock, professor of mechanical engineering at MIT, This new tool weve provided can be run on various models to see where these traps are predicted to be, and thus the most likely locations for a stranded vessel or missing person. He adds that, This method uses data in a way that it hasnt been used before, so it provides first responders with a new perspective.
The TRAPS acronym stands for TRansient Attracting Profiles. Its an algorithm based on a Eulerian mathematical system developed by lead study author Mattia Serra and corresponding author George Haller of ETH Zurich. Its designed to discover hidden attracting fluidic structures in an onrush of changing data.
The traps the researchers seek are regions of water that temporarily converge and pull in objects or people. The key thing is, says Peacock, the traps may not have any signature in the ocean current field. If you do this processing for the traps, they might pop up in very different places from where youre seeing the ocean current projecting where you might go. So you have to do this other level of processing to pull out these structures. Theyre not immediately visible.
