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: 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: 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: This study reveals that increased sea-ice formation over winter leads to more intense phytoplankton blooms and higher carbon export in the Northeast Weddell Sea the following summer. However, carbon export beyond the winter mixed layer is not directly proportional to primary production, suggesting different mechanisms at play. The spatial variability in the response of phytoplankton blooms to sea-ice volume highlights the need to consider spatial heterogeneity in the biological carbon pump's response to future sea-ice changes.

Summary: The study found that temperate lakes are experiencing surface warming and deep water cooling, with surface warming correlated positively with air temperature and deep water cooling positively correlated with deep water temperature and spring mixing period length. Deep water cooling shows a lag effect and is correlated with global temperature anomaly and spring North Atlantic Oscillation index. Increasing summer stratification strength and duration may lead to changes in lake ecosystems.

Summary: The study found that the response of lake ecosystems to ice-off date varied across different latitudes and types of lakes. Northern lakes quickly stratified after ice-off, with early ice-off years resulting in significantly warmer deep water temperatures. However, in southern lakes, ice-off date was not correlated with the onset of stratification but was more influenced by control on deep water temperature and oxygen.

Summary: Lake ice phenology in Central Asia was studied using MODIS daily LST products from 2002 to 2020. The results showed regional differences in the trends of lake ice phenology, with lakes near Kunlun Mountains experiencing delayed freeze-up and lakes in southwestern Central Asia showing advancing freeze-up and breakup. Correlations with local and climatic factors indicated that heat was the main driver of the breakup process, while precipitation influenced freezing time and wind speed affected the time of complete ice freezing.

Summary: Analysis of the spatio-temporal dynamics of ice phenology in Qinghai Lake from 2000/2001 to 2019/2020 shows a decrease in freeze-up duration, full ice cover duration, and ice cover duration, while break-up duration has increased. The increase in temperature resulted in an increase in precipitation, leading to an increase in break-up duration and a decrease in freeze-up duration.

Summary: Understanding the dynamics of phytoplankton bloom phenology in the Atlantic sector of the Southern Ocean revealed the importance of sea ice retreat and zooplankton grazing in driving bloom initiation and termination, respectively. The study also highlighted the spatial correlation between primary productivity and topographic features, suggesting natural fertilization as a contributing factor. Further investigation into the identified bloom regimes in the area may help inform spatial management strategies and anticipate potential shifts in bloom timing due to environmental changes.

Summary: This study analyzed pond diatom communities collected during an Antarctic expedition a century ago and compared them with modern samples, finding historical samples to be almost identical to modern ones with no evidence of exotic introductions. However, a shift in diatom species dominance in the pond nearest to the expedition base was observed, potentially attributed to changing precipitation patterns affecting conductivity. These results provide important data for assessing human and climate impacts in Antarctic lacustrine habitats.

Summary: Land use within a watershed affects stream channel morphology, hydrology, and solute transport processes. This study compared two stream sites with different channel morphologies and land use conditions. The results showed that the forested stream had a wide range of transport mechanisms and substantial exchange with both surface and hyporheic transient storage. In contrast, the agricultural stream had a narrower range of solute transport behavior, with predominantly surface transient storage.

Summary: This study examines the relationship between DOC and stream discharge in the glacial meltwater streams of the McMurdo Dry Valleys in Antarctica. The findings suggest that the autochthonous organic matter pools have sufficient DOC generation rates to maintain chemostasis in these streams. A conceptual model is proposed to explain the key components that enable chemostatic DOC-q behavior in these streams.

Summary: This study presents 4 years of sensor data on dissolved organic carbon (DOC) and nitrate-nitrogen (NO3-N) from a snowmelt-dominated catchment in the Rocky Mountains. The results show that solute responses to melt pulses and rainfall pulses differ, and the responses to daily cycles and individual events are also different from longer-term seasonal behavior they combine to generate.

Summary: The study applies an unsupervised clustering method to analyze time-lapse electrical resistivity (ER) models in order to delimit the hyporheic extent and quantify changes in surface-groundwater exchange. The findings demonstrate that unsupervised clustering can effectively distinguish solute transport signals from noisy background inversions and identify functional zones with unique transport characteristics.

Summary: This study examines the dynamics of mountain ecoregions in the western United States by collecting hydrometric and geochemical data from a semi-arid headwater catchment in Colorado. The research finds that precipitation inputs in mountain catchments shift seasonally, resulting in spatiotemporal differences in source area contributions to streamflow. The results highlight the importance of understanding and managing these dynamic shifts in hydrologic connectivity for land and water resource management, particularly in the face of rapid climate changes.

Summary: The study focuses on the impact of changing sea ice seasons and meteoric water on phytoplankton community composition and cell size in coastal West Antarctic Peninsula waters. The research reveals that the variations in sea ice seasons have a significant effect on phytoplankton biomass and species composition, while cell diameter changes are related to precipitation. The tight coupling between sea ice, meltwater, and phytoplankton species composition suggests that continued warming in the area will have implications for seasonal dynamics in the ecosystem.

Summary: Stream solute tracers are commonly injected to study transport and transformation, but their results are biased towards shortest and fastest storage locations. This study demonstrates a novel approach to observe mass stored beyond traditional detection limits, explaining the fate of previously considered lost solute tracer mass. These unmeasured flowpaths lead to lower magnitudes of gains and losses in individual reaches, suggesting an upper limit on actual behavior inferred from solute tracers.

Summary: Glaciers play a critical role in supplying water to downstream systems, especially in arid polar environments. However, we have limited understanding of the patterns and processes that generate the geochemical signature of meltwater on glacier surfaces. Through studying glaciers in the McMurdo Dry Valleys of Antarctica, we found that the overall meltwater chemistry is influenced by local sediment sources and regional wind patterns. Additionally, the physical and geochemical processes occurring within the glaciers strongly influence the supra- and proglacial stream chemistry.

Summary: This study explores the long-term dynamics of dissolved oxygen (DO) in hyporheic zones and highlights the influence of hydrologic exchange and biogeochemical reactions on DO levels. Through continuous monitoring of temperature and DO at different depths, it is found that DO in the hyporheic zone exhibits regular daily fluctuations, but does not align with temperature patterns. Results suggest that antecedent snowpack conditions and microbial communities play a significant role in regulating hyporheic DO.

Summary: Healthy river ecosystems require a complex interaction of physical and biological processes, including hydrologic exchange flows (HEFs), to maintain their status. HEFs can act as nonpoint pollution sources, making it difficult to pinpoint the origin of pollutants in large rivers. This research in the Columbia River near Richland, WA found anomalies in temperature and electrical conductivity that indicate dynamic heat and solute transfer through HEFs, with inflows along agricultural land use areas showing increased nitrate concentrations.
