Ice Cover and Extreme Events determine Dissolved Oxygen in a Placid Mountain Lake

Abstract A decrease in hypolimnetic dissolved oxygen (DO) is a commonly seen effect of climate change. However in oligotrophic Lake Tovel (Italy), a deep mountain lake, annual mean DO (% saturation) has increased from near anoxia to > 20% in the bottom layer (35‐39 m) from 1937 to 2019. We analyzed long‐term patterns of DO […]
