Short summary
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 study presents a high-resolution, multi-year dataset of δ²H, δ¹⁸O, d-excess, and Δ¹⁷O in precipitation from Seoul, Korea (2016–2020). The data reveal seasonal and interannual isotope variability in a monsoon-influenced mid-latitude region, reflecting moisture sources and atmospheric circulation. This integrated isotope dataset supports evaluation of isotope-enabled climate models, advances hydroclimate research in East Asia, and is openly available for the Earth system science community.

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.

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.

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.

Short summary
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.
