Turbulent mixing and heat fluxes under lake ice: the role of seiche oscillations
2018
Hydrology and Earth System Sciences Discussions
<p><strong>Abstract.</strong> We performed a field study on mixing and vertical heat transport under ice cover of an Arctic lake. Mixing intensities were estimated from small-scale oscillations of water temperature and turbulent kinetic energy dissipation rates derived from current velocity fluctuations. Well-developed turbulent conditions prevailed in the stably stratified interfacial layer separating the ice base from the warmer deep waters. The source of turbulent mixing was identified as
