Summary: The distribution of sedimentary organic carbon and nutrients in endorheic lakes is influenced by water flow, external sources, and environmental factors, and water circulation favors the accumulation of these substances in the northwestern part of the lake.

Summary: By comparing the bacterial communities of free-living (FL) and particle-associated (PA) in Lake Baikal, it was found that there were differences in the composition and diversity of these communities across different nutrient intake areas and seasons. The microeukaryotic communities also showed increased diversity in summer, possibly contributing to the increase in bacterial diversity. The co-occurrence network analysis revealed that FL communities had more interconnected bacterial OTUs than PA communities.

Summary: The study monitored the seasonal cycle of ice formation and breakup in Lake Hanzhang, China, during the winter of 2020-2021. The research categorized the ice season into growth, equilibrium, and melting stages. It found that the thickness of ice increased during the growth stage, remained stable during the equilibrium stage, and decreased during the melting stage. The study also explored the heat balance and heat fluxes in ice-covered lakes in mid-latitude dry climates, which have rarely been studied before.

Summary: This study investigated the effects of snow and remineralization processes on nutrient distributions in multi-year landfast sea ice in Lutzow-Holm Bay, East Antarctica. It was found that the upward growth of the multi-year fast ice was attributed to the accumulation of snow over the years. Nutrient concentrations were lower in the shallow ice due to the replacement by clean and fresh snow, while remineralization dominated in the deeper ice from seawater origin. Additionally, the biological uptake was more dominant in relatively young ice, whereas older ice was more prone to remineralization under the physical process of brine drainage.

Summary: This study investigated nitrogen metabolism pathways and microorganisms involved in these pathways in seasonally frozen lakes during the ice-covered period. The results showed that ammonia assimilation was the most important nitrogen transformation pathway, and Bacteria and Proteobacteria were the dominant microorganisms involved in nitrogen metabolism. Gene sequences related to nitrogen fixation, nitrification, denitrification, dissimilatory nitrate reduction to ammonium, and ammonia assimilation were significantly higher in sediment compared to surface and subsurface water. Furthermore, 15 biomarkers of nitrogen-converting microorganisms exhibited significant variation between sampling levels. The findings of this study contribute to our understanding of the nitrogen cycle in seasonally frozen lakes.

Summary: This study evaluates the relative importance of different environmental factors on the diversity and stability of plankton communities in shallow eutrophic lakes in China. The results show that physical and chemical indicators, nutritional parameters, and light effects have a significant impact on zooplankton community dynamics, while physical and chemical parameters have the greatest influence on phytoplankton community composition.

Summary: The authors utilize electron diffraction to characterize supercooled water in the no man's land for the first time, narrowing down possible explanations for its anomalies. Systematic characterization of deeply supercooled water has been elusive due to rapid crystallization, but their experimental approach allows for rapid preparation and analysis. The study shows that as water is cooled, its structure evolves smoothly towards amorphous ice, providing new insights into the origin of water anomalies.

Summary: The study conducted in Lake Ulansuhai, a shallow eutrophic lake in Northern China, found that eutrophication significantly decreased CO2 emissions from the lake, while increasing CH4 emissions, resulting in a CH4 and CO2 emission ratio of approximately 2 in terms of global warming potential.

Summary: Understanding the impact of lake ice on microplastics (MPs) in lake waters is crucial for addressing plastic pollution. This study found that ice formation reduced the abundance of MPs in lake waters, while increasing their concentration in the ice. Additionally, MPs showed a distinct spatial pattern during the ice-covered period compared to the ice-free period.

Summary: The study estimated the net exchange of nitrogen and phosphorus species in estuarine lakes, revealing high efflux of NH4+ in dark conditions and significantly decreased efflux in light conditions. The presence of Chara hornemannii Wallman was found to have a large impact on NH4+ efflux, and it is expected that increased freshwater flow from the Everglades will influence NH4+ release in lakes.

Summary: This Special Issue focuses on research articles that examine glacier and lake ice variations at the geographical scale, as well as ice properties and their practical applications at the engineering scale through laboratory tests and numerical modeling. It also includes research on ecosystems under lake ice. The main goal of the issue has been achieved through the collaborative efforts of authors, anonymous reviewers, and editorial managers. Contributions from researchers in different parts of China and international cooperation partners have resulted in 1 review article and 15 research articles being included in this Special Issue. These articles cover a wide range of topics, including water resources from Chinese mountain glacier variation, lake ice phenology at different latitudes and altitudes worldwide, ice properties from laboratory experiments and numerical modeling, ice engineering in China and the Arctic, and ecosystems under lake ice at different temporal and spatial scales. The Special Issue is significant in promoting research on ice properties and their applications in various environments, particularly in water ecosystems under ice during seasonal ice periods.

Summary: First-principles MD simulations demonstrate the spontaneous freezing transition of 2D liquid water within hydrophobic nanoslits, leading to the observation of various 2D ices under different pressure and temperature conditions. The study reveals the formation of a monolayer ice with zigzag water chains and a bilayer ice resembling double surface layers of bulk ice-VII in different width nanoslits at specific pressure and temperature conditions. These 2D crystalline ices do not obey the ice rule, highlighting the unique phase space accessible through first-principles simulations.
