TL;DR: In this article, a review of the present advances in understanding the governing physical processes in seasonally ice-covered lakes is presented, focusing on the general description of the main physical mechanisms that distinguish the ice covered season from open water conditions.

TL;DR: How under-ice conditions alter lake physics and the ways that this can affect the distribution and metabolism of auto- and heterotrophic microorganisms are highlighted.

TL;DR: In this article, the authors argue that current understanding of physical and biogeochemical processes in freshwater systems is sufficient to begin to construct such models, and a path forward is proposed, arguing that the largest impediment to fully representing lakes in the climate system lies in the handling of lakes that are too small to be explicitly resolved by the climate model, and that make up the majority of the lake covered area at the resolutions currently used by global and regional climate models.

TL;DR: Investigation of the fluxes of these two gases across the surface of oligotrophic Lake Stechlin using a floating chamber approach determined that an average of 145 L m(–2) d(–1) of gas is required to exit the surface layer via microbubbles to produce the observed elevated k600,CH4.

TL;DR: In this paper, the Richardson number was used to distinguish thermally stratified during a large portion of the year from those that stratify seasonally based on lake water transparency, lake length, and an annual mean estimate for the Monin-Obukhov length.
