by Irène Mopin (Lab-STICC UMR 6285, ENSTA) and Noémie Favennec (MUSIDANSE Université Paris 8, ENSTA) Noise pollution is one of the least understood forms of pollution. Invisible to the naked eye and difficult to detect without specialised listening equipment, it nevertheless profoundly disrupts marine ecosystems. In her PhD thesis, Noémie Favennec explores this issue. Her research, supervised by Makis Solomos (University of Paris 8) and Irène Mopin (ENSTA), lies at the inters

Satellite view of small ocean eddies off Cape Town, South Africa. For decades, it has been assumed that motions smaller than the mesoscale would decay into turbulence, draining energy from the mean ocean circulation. From limited-area observations and new numerical modelling studies, it is now evident that energy can also transfer to larger scales — the inverse energy cascade —strengthening the circulation and enhancing vertical fluxes, as well as driving mixing. WHIRLS will

Written by Sabrina Speich, John Abraham, Kevin Trenberth, Lijing Cheng Published on 9 June 2026 from The Conversation The world relies on a modest number of countries to keep watch over the ocean. That arrangement is starting to fail. Europe and Asia must now decide whether to let the system unravel, or to take it up together. Right now, in every ocean basin on Earth, a global network of instruments measures the state of the sea. Research ships steam along oceanographic trans

A vast network of marine sensors is being dismantled by the Trump administration, and other programs are threatened. This will result in a loss of data essential for understanding global warming or predicting extreme events, according to researchers. By Audrey Garric.
