Summary: The study analyzed the summer lake color phenology of over 26,000 lakes in the United States using a new remote sensing data set, LimnoSat-US, revealing five distinct phenology groups and patterns of phytoplankton succession. The frequency of transitions between phenology groups is linked to lake and landscape level characteristics, with lakes having high inflows and low seasonal surface area variation being more stable.

Summary: The study reveals that climate change is causing a decrease in ice cover in Northern Hemisphere lakes, with air temperature changes playing a significant role. Future projections suggest that lakes in Northern Poland will continue to experience reduced ice cover duration and thickness, with smaller and inland lakes being more severely affected. The probability of ice-free winters is expected to increase across all scenarios, particularly in smaller and deeper lakes exposed to wind.

Summary: Springtime in temperate lakes is characterized by a phytoplankton bloom, followed by a grazing crustacean zooplankton bloom. The timing and species composition of these events may be influenced by antecedent conditions and climate change. Winter conditions have a strong impact on the succession and species composition of both phytoplankton and zooplankton.

Summary: A remote sensing-derived lake ice phenology database covering all lakes in Alaska from 2000 to 2019 was constructed to analyze the trends of earlier breakup and later freezeup of lake ice in the region. The dataset showed significant trends towards earlier or later ice breakup and freezeup for various lakes, with most significant trends observed in lakes north of the Brooks Range. This dataset contributes to the understanding of interactions between lake processes and climate change, supporting research on biogeochemical, limnological, and ecological regimes in Alaska and pan-Arctic regions.

Summary: The study found that lake ice-on dates are getting later, ice-off dates are getting earlier, and ice duration is getting shorter on average over the past century. The trends in ice-on and ice duration have increased significantly in the last 25 years compared to previous periods, with more extreme events contributing to the loss of lake ice cover.

Summary: Research suggests that delaying ice cover onset can impact pelagic food web processes and phenologies, such as increasing algal resource and primary consumer densities in early winter, expanding winter-active consumer populations, and altering nutritional structure after ice-off.

Summary: Shallow lakes are important freshwater ecosystems that support biodiversity and ecosystem services, with sediment playing a key role in regulating the lake's ecosystem. Monitoring the sediment in the shallow coastal lake of Xuno has shown its impact on the water and macrophytes.

Summary: By monitoring the lake ice process of Chagan Lake, it was discovered that a large-scale fracture has been repeatedly observed on images since 1986, and a novel method for automatically extracting these fractures was proposed. A field campaign also confirmed the existence of the lake ice fractures and explained the development of fractures.

Summary: The study found significant relationships between air temperatures and ice phenology in boreal lakes, with both ice-on and ice-off dates being predictable from seasonal air temperatures. Despite non-significant trends in ice-off dates, ice-on dates were trending later over time, and both ice-off dates and duration of ice-cover were becoming increasingly variable. Additionally, regional variations in ice-phenology and snow and ice-thickness across different sized lakes displayed significant relationships to lake size.

Summary: Analytic methods are useful for studying lake ice climatology by considering ice phenology, thickness, and extent. Factors such as lake depth, size, water quality, solar radiation, air-lake interaction, and heat flux from bottom sediment can be compressed into a few forcing factors for analytic modeling. The use of a two-layer temperature structure and a non-inert conduction law allows for temperature and ice thickness solutions, while a time scale analysis determines the applicability of the equilibrium method for lake ice climatology. A non-steady solution is required for ice melting.

Summary: A new automated method was developed to extract lake ice phenology parameters by capturing the temporal pattern of the transitional water/ice phase using a parameterized time function. The method is based on MODIS daily temperature products, which have unique potential for monitoring lake ice cover. The study showed strong potential for estimating and monitoring ice phenology on different types of lakes.

Summary: Traditionally, lakes are classified based on their thermal regime and trophic status, but this classification method is not sufficient to understand seasonally ice-covered lakes. Research has found that differently sized and deep seasonally ice-covered lakes exhibit different thermal stratification characteristics, leading to the proposal of new classification terms.

Summary: Arctic lakes are experiencing decreased ice cover duration and thickness, which has implications for lake ecosystems. However, our understanding of the geochemical dynamics of nutrients and oxygen beneath ice cover in high Arctic lakes is limited. This study presents data from Immerk Lake on Devon Island, Canada, showing the importance of the extended winter season for the regeneration of silicate, a key nutrient for diatom populations in Arctic lakes.

Summary: Mounting evidence suggests that climate warming is significantly impacting lakes in the Tibetan Plateau. This study uses statistical models and simulations to demonstrate the future decrease in lake ice duration and increase in lake expansion due to warming. Additionally, the study finds that lake expansion is insensitive to glacier mass loss.

Summary: This study aims to simulate the lake ice conditions in Nam Co lake using a physics-based one-dimensional lake ice model. The air density schemes within the model were modified to improve the accuracy of the simulation. The process of lake ice sublimation and the effect of lake water salinity on the freezing point were also included. The results show that the improved model better reproduces the lake surface water temperature, lake ice thickness, and lake ice phenology at Nam Co.

Summary: Airborne electromagnetics is a useful geophysical tool for mapping glacial and hydrogeological structures in polar environments, providing significant spatial coverage and distinguishing geological units based on their electrical properties. Research has shown that induced polarization effects can disrupt traditional EM workflows, but workflows designed to handle IP effects can produce reliable geological interpretations.

Summary: The concentrations of solutes in seepage lakes are influenced by precipitation and groundwater inputs. Seepage lakes in areas where road salt is applied may face a high risk of salinization. Monitoring of Sparkling Lake over 40 years shows that chloride concentrations have steadily increased, indicating terrestrial retention as a factor. When modeling future chloride contamination risk, the retention of chloride on the landscape should be considered.
