Summary: The study revealed that the plastic particles trapped in Arctic sea ice are comparable to those in other Arctic basins, suggesting a strong linkage between the Western Arctic Ocean and the Arctic Central Basin. Additionally, it highlighted the role of the Western Arctic Ocean ice zone as a sink for global microplastics and a potential source for Arctic microplastics.

Summary: This paper introduces a sea ice prognostic model that successfully simulates the physical properties of snow and ice over the Arctic Ocean during the winter season. The model utilizes a one-dimensional thermodynamic diffusion model, satellite data, and Lagrangian ice tracking, with high correlations between simulated variables and in situ measurements. The nudging of satellite-derived temperature data significantly improves the thermal structure of the model, serving as a key element for successful simulation of other variables.

Summary: The biogenic substance E-indigo can form supramolecular, hydrophobic structures that act as a gliding layer with low friction coefficient against polar surfaces. By utilizing directed friction, high pressure, and tempering techniques, structures with excellent gliding properties can be achieved. Field tests on snow have shown promising results compared to fluorinated and non-fluorinated waxes. QSAR data demonstrate that the application and abrasion of the thin indigo layers are harmless to health and environmentally friendly.

Summary: The hydrogen bond network plays a crucial role in the physical and chemical properties of water. The relative intensity of weakly hydrogen-bonded water molecules increases with higher excitation energy in liquid water. The Raman spectrum of snow reveals a larger contribution from weakly hydrogen-bonded water molecules at the surface compared to bulk ice. Further enhancement of surface contribution in the snow spectra is observed with excitation sources in the UV-C range.

Summary: The study utilized a snow/ice enhanced WRF-ice model to analyze the meteorological conditions during a strong cyclone event over the Antarctic Peninsula in 2017, accurately reproducing the evolution of the cyclone and simulating near-surface conditions in agreement with observations. Numerical simulations indicated that blowing snow sublimation can have significant effects on the lower atmosphere, leading to moistening and cooling in dry air, while in warm and humid areas, cloud enhancement by blowing snow can result in varying surface temperatures due to cloud radiative forcings.

Summary: Increasingly larger portions of the Greenland ice sheet are melting and refreezing seasonally due to global climate warming. Our study shows that multi-frequency passive microwave measurements effectively distinguish seasonal meltwater on the surface and deeper ice layers. The results indicate persistent seasonal subsurface meltwater occurrences that are concealed from high-frequency observations.

Summary: A theoretical heat model was developed to predict the liquid water content (LWC) of snow, which was validated by experimental measurements. It was found that LWC significantly affects snow adhesion on surfaces, leading to different snow shedding mechanisms based on different LWC levels.

Summary: This paper presents the retrieval of clean snow properties using EnMAP hyperspectral observations for the first time. The study was conducted near the Concordia station at the Dome C Plateau in Antarctica where the atmospheric effects are weak. Ice grain size, snow specific surface area, and snow spectral and broadband albedos were obtained using EnMAP measurements. Additionally, a technique for retrieving trace gas concentrations from EnMAP observations over snow surfaces was proposed, and good agreement with ground-measured parameters was found.

Summary: Melting glacier ice surfaces host active microbial communities that play important roles in glacial melt, biogeochemical cycling, and downstream ecosystems. However, these communities are still poorly understood. This study found similar microbial abundances in surface meltwaters from eight glaciers across Europe, North America, and western Greenland, and these abundances were correlated with suspended sediment concentration. It is predicted that a large number of these microbes will be released into downstream ecosystems in the next few decades.

Summary: This study evaluates the suitability of using the finite volume method to quantify transient energy and mass fluxes on frozen surfaces compared to the traditional glaciological energy balance approach. The methods were applied to datasets from a glacier in the semi-arid Andes and an Antarctic ice shelf, estimating the impact of time-varying surface irradiation, wind velocity, air temperature, and humidity on temperature, liquid water, and heat fluxes over a 30-month period. The results of the energy and mass balances were validated against previously published global balances and meteorological datasets.

Summary: The lack of field observation data on ice-snow has led to a poor understanding of its characteristics and uncertainty in ice process simulation. This study conducted a field investigation using a multi-angle observation instrument and measured the Bidirectional Reflectance Distribution Function of snow/ice/ice-snow. It was found that the characteristics of ice-snow are similar to snow when a small amount of fresh snow is deposited on the ice surface, but will significantly change when the surface snow undergoes metamorphism, which can affect the accuracy of snow and ice monitoring using remote sensing data.

Summary: This study provides estimates of summertime evaporation over Lake Zub, located in the Schirmacher oasis, East Antarctica. The eddy covariance method was found to be the most accurate, and a new combination equation using meteorological observations was suggested for better estimation. The study highlights the importance of accurate measurement and estimation methods for understanding climate processes in Antarctica.

Summary: Snow is the dominant form of precipitation in the High Arctic and has a significant impact on the climate system and ecosystems. This study reviews the observed and projected snow cover conditions in the region, including snowfall, snow cover duration, snow cover extent, snow depth, and snow water equivalent. While overall snowfall has increased, some snow cover metrics, particularly in spring and summer, have shown consistent decreasing trends. However, snow depth and snow water equivalent have mostly increased, but are projected to decrease by 2030.

Summary: Glacier and ice sheet surfaces are home to diverse microbial communities that influence biogeochemical cycles and ice melting. Using molecular analyses and incubations, this study found that a high proportion of active bacteria are present on snow and ice surfaces, even when frozen. These findings have important implications for understanding the impact of climate change on polar regions and for studying potential life on icy worlds, emphasizing the need for a better understanding of microbial activity on glacier surfaces.

Summary: In recent decades, all ocean basins have experienced significant warming and rising sea levels, with important regional differences due to distinct processes at different timescales. It is essential to move towards more sophisticated data-driven techniques and diagnostic prediction models to interpret observations of ocean warming and sea level variations.

Summary: The study demonstrates the use of a new machine learning-based methodology to reconstruct historical sea level tide gauge records from proxy data, providing a dynamic representation of coastal sea level variations linked to slow and persistent natural processes. The machine learning framework introduced allows for modeling the complex nonlinear dynamics of regional ocean properties, improving the analysis of past climate-driven sea level variability.

Summary: Initialized climate predictions offer distinct benefits for multiple stakeholders on subseasonal, seasonal, and decadal timescales. While there have been some skilful predictions in various areas, challenges remain, and future efforts should focus on reducing model error, improving communication of forecasts, and enhancing process and mechanistic understanding to increase predictive skill and confidence.
