Climate Warming Improves Oxygen Mixing in a High-Altitude Lake

by D. Scott Mackay 10 September 202020 April 2022

Long term weather and lake data from a high elevation lake in the Alps demonstrate that climate warming may actually improve the ability of high-altitude deep lakes to mix their waters.

Hydropower and Bugs

by E. Wohl 16 December 201911 January 2022

Alpine hydropower plants commonly flush sediment that accumulates at intakes, but the associated rapid rise in discharge, turbidity, and streambed instability put aquatic insects at risk.
