Special Issue Information

Dear Colleagues,

Climate warming is changing the physical regime of seasonally frozen lakes, especially the duration of freeze-up, water temperature, mixing regime and gas regime. These factors have a significant impact on the functioning of aquatic ecosystems in the annual cycle. Despite the increased interest in the winter period, we still know very little about how hydrophysical processes and ecological cycles in ice-covered lakes are changing as the climate warms. It is extremely important to fill this gap in order to understand the prospects for the development of aquatic ecosystems in the new conditions.

The main purpose of this Special Issue is to attract articles devoted to assessments of changes in the thermohydrodynamics and gas regimes of ice-covered lakes against the backdrop of climate warming.

The general topics of this Special Issue of Water are as follows:

1) Climatic factors that determine the evolution of the gas regime and thermohydrodynamic processes and phenomena in lakes covered with ice—reduction of the ice period, increased under-ice mixing, earlier onset of radiatively driven convection, under-ice oxygen production, etc.

2) Hydrophysical processes and phenomena that affect heat and gas fluxes at the water–ice and water–bottom boundaries, as well as inside the water column—internal waves, seiches, currents, eddies, heat and mass transfer with the bottom sediments, etc.

3) Formation and expansion of sub-lake taliks—influence on gas fluxes and thermal regime of ice-covered lakes.

4) Fluxes of gases in ice-covered lakes and the formation of seeps in ice.

5) Modeling of heat and mass transfer processes in ice-covered lakes.

6) Modern methods and approaches to the study of hydrophysical processes and gas regime in ice-covered lakes.

7) Ice and hydrochemical regime of meromictic and saline lakes.

8) Ice and hydrochemical regime of artificial water bodies (reservoirs).

9) Dynamics of aquatic ecosystems under the influence of the reduction of the freezing period; ecosystem modeling.

Therefore, this Special Issue aims to highlight the latest cutting-edge findings that may reveal trends in aquatic ecosystems under observed and expected climate and human impacts.

The calculation of the turbulent stress matrix using acoustic Doppler current profiler (ADCP) data remains a challenging problem in the study of geophysical flows. One of the ways to overcome the problem is to use a system of two coupled ADCP with pairs of beams intersecting at a certain depth. When device configuration is symmetric in horizontal, this setting makes it possible to estimate the stresses only for a small range of depths, close to the depth of beam intersection point. To overcome this restriction, in this paper the modified setting is proposed, when both devices are symmetrically turned in the horizontal plane. The X axes of the devices are not collinear for such setting, and two pairs of beams intersect at two different depths, which depend on the distance between the emitters and devices’ rotation angle, and can be chosen in advance. At each of these depths, six beam velocity variances can be directly calculated, as well as the correlation of those velocity components, which correspond to the intersecting beams. As a result, an overdetermined system of equations is derived for unknown stresses, for both depths. The method was approbated during the processing of two series of field data obtained in lakes during open water and ice-covered periods. In most cases, calculations lead to physically consistent results; in particular, the stress matrix turns out to be positive definite. The method’s limitations and perspectives of its development are discussed. Full article

Until now, the phenomenon of radiatively driven convection (RDC) in ice-covered lakes has not been sufficiently studied, despite its important role in the functioning of aquatic ecosystems. There have been very few attempts to numerically simulate RDC due to the complexity of this process and the need to use powerful computing resources. The article presents the results of Large Eddy Simulations (LES) of RDC with periodic external energy pumping, which imitates the diurnal variations in solar radiation in the subglacial layer of lakes in spring. The research is aimed at numerically studying the initial stages in the formation and development of a convective mixed layer (CML). A numerical calculation was carried out for three variants of external energy pumping that differed in intensity. A diurnal acceleration and suppression of RDC due to a change in external pumping was revealed for all three variants. The results of numerical simulations provide estimates of such integral parameters of RDC development as the rate of deepening of the lower boundary of the CML, and the rate of water temperature rise within this layer. It was shown that as the cumulative heating of the CML increases over several days, daily increments in temperature and depth slowed down; that is, the dependence of the integral RDC parameters on external pumping was nonlinear. The LES results on RDC parameters were in good agreement with our observational data. Full article
