Scientists from three joint research units (MARBEC, ENTROPIE and LIRMM) have just published a study using the latest technological advances to identify charismatic species of the marine megafauna of New Caledonia: dugongs, turtles and sharks. This work, entitled “Leveraging social media and deep learning to detect rare megafauna in video surveys” and published in the international journal Conservation Biology, is partly the result of the Pelagic research project financed by the Foundation for Research on Biodiversity (FRB) within its Centre for Biodiversity Synthesis and Analysis (Cesab), and is based on the collection of aerial videos financed by the Explorations de Monaco.
