Deepwater renewal in Lake Geneva in light of climate change

EPFL scientists have studied two mechanisms that can help bring oxygen to the depths of a lake—essential for preserving the lake's ecosystem. The classical deepwater renewal caused by surface cooling during winter is becoming ...

Red Sea may have a nursery for oceanic manta rays

The endangered oceanic manta ray Mobula birostris is an iconic marine creature, and yet surprisingly little is known about them. Now, a study led by KAUST researchers has provided insights into population demographics and ...
