Short summary
We studied how water from melting snow and ice changes as it moves through layered ice. Using laboratory experiments, we found that the water signal is altered by interactions between flowing water and the surrounding ice. Faster flow increased exchange along active pathways but reduced the amount of ice involved. These findings show that meltwater signals are modified before leaving snow or ice, improving our understanding of water movement in cold regions.

We created the first global collection of water measurements from glacier‑influenced rivers, lakes, snow, and ice to understand how melting glaciers shape water supplies. By combining data from many regions, we show clear patterns linked to climate and elevation. This work helps scientists and water managers better predict future water availability as glaciers continue to shrink.

This study presents a five-year (2016–2020) high-resolution record of precipitation isotopes (δ²H, δ¹⁸O, d-excess, and Δ′¹⁷O) in Seoul, South Korea. All isotopes exhibit strong seasonal cycles controlled by temperature, monsoon rainfall, and moisture source humidity. d-excess reflects source-region evaporation, while Δ′¹⁷O shows reduced seasonal sensitivity and highlights atmospheric mixing and transport processes, providing new constraints on East Asian hydroclimate dynamics.

This study integrates high-resolution ERA5 reanalysis with precise ice core isotope measurements to assess summer water isotope variability at Hercules Névé in East Antarctica. By focusing on the austral summer (DJF), it minimizes post-depositional effects and elucidates the roles of temperature, precipitation, and wind patterns, including effects from the Amundsen Sea Low and Zonal Wave-3. The 40-year record refines paleoclimate reconstructions and Antarctic climate understanding.

This study investigated ancient ice in the Elephant Moraine, East Antarctica. Using geophysical surveys and chemical analyses, we found surface ice of around 320 000 years old and ice thickness ranging from 200 to 800 m. These findings suggest that the Elephant Moraine region may preserve ice over 1 million years old at depths of several hundred meters. Recovering such ice is a key goal in paleoclimate research to better understand the climate history of Earth.

This research explores climate patterns recorded in Antarctic ice over the past two centuries. By analyzing ice layers, we identified connections between Antarctica's climate and tropical ocean conditions. Results show changing influences over time and highlight the Indian Ocean's key role in Antarctic snowfall. This improves understanding of how polar and tropical climates interact, crucial for future climate predictions.

This work examines the impact of artificial snow on the nitrogen cycle and groundwater quality at Mt. Balwang in South Korea. By analyzing stable isotopes of nitrate (δ15N–NO3−) and water (δ18O–H2O), we found that artificial snow contributed 49.5 % of nitrogen in mountain groundwater, surpassing natural snow and rain. The results highlight the environmental risks of artificial snow, including nitrogen accumulation and potential ecosystem disruption, amidst climate change-driven reliance.

Blue-ice areas (BIAs) have several advantages for reconstructing past climate. However, the complicated ice flow in the area hinders constraining the age. We applied state-of-the-art techniques and found that the ages cover the last deglaciation period. Our study demonstrates that the BIA in northern Victoria Land may help reconstruct the past climate during the termination of the last glacial period.

Short summary
We present 462 paired measurements of stable oxygen and hydrogen isotopes in monthly precipitation from 15 sites on Jeju Island, South Korea, collected between 2000 and 2003. Isotope values were generally lower in summer and decreased with elevation. Published with weather data and sampling information, this historical dataset provides a baseline for future monitoring and supports research on groundwater recharge and the island’s water cycle.
