Hydrophysical Parameters and Gases in Ice-Covered Lakes

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.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 250 words) can be sent to the Editorial Office for assessment.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Water is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2600 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
