Sonar-MASt3R is a new underwater mapping technique developed at MIT and the Woods Hole Oceanographic Institution (WHOI) that may allow vehicles to see through murky, low-visibility waters.

This study reviews ecological operation practices in China's Tarim and Irtysh River Basins, focusing on innovations such as multiscale reservoir ecological operations, ecological infiltration irrigation, and ecological water conveyance strategies. These approaches have effectively restored riparian vegetation, enhanced groundwater recharge, and improved biodiversity while balancing socioeconomic demands. The paper also discusses persisting challenges like climate variability and competing water demands. Lastly, the paper proposes an integrated framework combining reservoir regulation, ecological flow reconstruction, and targeted water delivery technologies to enhance sustainable water management in arid regions.
