Ice Cover Redirects Currents: Swedish dye studies track hidden flows; lakes keep layered beneath ice
In Sweden, hydrologist Lars Bengtsson undertook winter tracer experiments in lakes to understand dye dispersion beneath ice cover. These studies revealed how wind-induced tilting of ice creates seiche currents below, although these currents are notably less vigorous than the summer mixing that typically occurs in lakes. Consequently, the presence of…
