主　　题：underwater enable visibility 

摘      要：The deep ocean,characterized by its immense depths and absence of global positioning system(GPS)functionality,presents considerable challenges for search and rescue *** by the geolocalization capabilities of migratory marine animals,Bai et *** a novel method for underwater geolocalization using the polarization patterns of light in the underwater *** a sextant using these underwater polarization patterns,the study determines geolocation in underwater *** prior skepticism,even in low-visibility waters,these patterns,learned through a deep neural network,provide geolocation accuracies of 55 km at 8m and 255 km at 50 *** pioneering approach offers implications for search and rescue and hints at navigation mechanisms in marine animals.
