An artificial intelligence system developed at EPFL can produce 3D maps of coral reefs from camera footage in just a few minutes. It marks a major leap forward in deep-sea exploration and conservation capabilities for organizations like the Transnational Red Sea Center (TRSC).

Ecological communities in rivers and lakes are responding to climate change in a similar way to communities on land. This is shown by the first comprehensive comparison of freshwater and terrestrial ecosystems around the globe, co-led by Eawag and WSL. When temperatures rise, warm-loving species are the main beneficiaries. One surprising exception may be the plankton.

Engineers from EPFL and partner organizations have developed a method for classifying lacustrine deltas based on morphological parameters, in order to determine which of the deltas severely altered by human activity are best suited for restoration to their natural state.

Glacier-fed streams are undergoing a process of profound change, according to EPFL scientists in a paper appearing in Nature Geoscience. This conclusion is based on the expeditions to the world’s major mountain ranges by members of the Vanishing Glaciers project.

As part of the Ice Memory initiative, PSI researchers, with colleagues from the University of Fribourg and Ca’ Foscari University of Venice as well as the Institute of Polar Sciences of the Italian National Research Council (CNR), analysed ice cores drilled in 2018 and 2020 from the Corbassière glacier at Grand Combin in the canton of Valais. A comparison of the two sets of ice cores published in Nature Geoscience shows: Global warming has made at least this glacier unusable as a climate archive.
