Seasonal overturn and stratification changes drive deep-water warming in one of Earth's largest lakes

E. J. Anderson, C. A. Stow, et al.

This groundbreaking study by Eric J. Anderson and colleagues dives into three decades of high-frequency subsurface water temperature data in Lake Michigan, uncovering alarming trends in deep-water winter warming. These shifts not only signal changes in fall overturn and stratification but also carry significant consequences for the lake's ecosystem.

Abstract

This study investigates deep-water warming trends in Lake Michigan using three decades of high-frequency subsurface water temperature data. The results show that deep water temperatures are rising in the winter and that this warming is linked to changes in the timing of fall overturn and stratification. These shifts in thermal regimes have profound implications for the lake's ecosystem.
