We developed a high-resolution computer model to simulate how the ocean, sea ice, and ice shelves interact around Antarctica. This helps us understand their critical role in global climate and sea-level rise. Our model successfully captures essential features like major currents and seasonal ice changes. Despite some remaining biases, it provides a useful tool for predicting future changes in this vital and rapidly evolving region.

Ancient air trapped in ice bubbles is a valuable archive for studying past climates. However, trapped air can be altered by gas loss through pumping in laboratory. We quantified the characteristics of this loss for the first time based on controlled ice pumping experiments. We discovered that O2 and Ar escape simultaneously through ice microcracks. Crucially, we found that gas loss corrections considering both O2 and Ar significantly reduced data scatter, recovering clearer climate signals.

Volcanic eruptions can significantly affect the Earth's climate. Reconstructing past volcanic history can provide valuable information for climate modeling. Our study provides a new volcanic record from Dome A, the highest ice dome in Antarctica. Using this record and three other volcanic records from Antarctica, the prominent volcanic events, the change in volcanic frequency and flux, and the variation of snow accumulation rates at Dome A over the past 4000 years are investigated.

Atmospheric particles over the ocean contain organic nitrogen, affecting climate and ecosystems. This first pole-to-pole study of marine air reveals a strong latitudinal divide, with higher concentrations in the polluted Northern Hemisphere. A key discovery is that air influenced by Antarctic sea ice is enriched in organic nitrogen, revealing a major natural source. Our new dataset improves climate models by clarifying how human emissions and natural processes shape the atmosphere.

We reveal for the first time the global variations of PAHs and derivatives in marine air. We found that marine aerosols in East China Sea (ECS) and Western Pacific (WP) were significantly affected by coal and engine combustion, while those in Bismarck Sea (BS) and East Australian Sea (EAS) were mainly influenced by wildfire and coal combustion. The Antarctic Ocean (AO) was dominated by biomass burning and local shipping emissions. This finding helps elucidate the mechanism of the global PAH cycle.

Landlocked lakes are crucial to the Antarctic ecosystem and sensitive to climate change. Limited research on their distribution prompted us to develop an automated detection process using deep learning and multi-source satellite imagery. This allowed us to accurately determine the landlocked lake open water (LLOW) area in Antarctica, generating high-resolution time series data. We find that the changes in positive and negative degree days predominantly drive variations in the LLOW area.

Scarce reliable greenhouse‑gas observations plague inland Antarctica. The low‑power (<350 W) CRUX‑1.0 integrates four subsystems for simultaneous CO₂‑O₃ monitoring. Its one‑month Taishan Station test shows stable performance, with post‑calibration CV (coefficient of variation) < 5.6 %. Measured mixing ratios exhibit good comparability with South Pole Station data. Capable of unattended operation, CRUX‑1.0 is promising for data‑scarce polar inland deployment.

Stake measurements underestimate Antarctic surface mass balance (SMB) due to firn compaction. Using a firn densification model, we correct 2008-2024 stake records from Dome A. The corrected mean annual SMB is 24.14 kg m-2 yr-1, 8.8 % higher than uncorrected values, whereas RACMO2.4p1 gives 17.50 kg m-2 yr-1. The net vapor flux is equivalent to 5.7 % of the total mass input. This framework provides observational benchmarks for climate models, and supports oldest‑ice drilling at Dome A.

We studied how chemicals released from plants and pollution interact in the atmosphere, affecting air quality and climate. By combining laboratory experiments and chemistry models, we tracked unique chemical fingerprints to understand how nitrogen compounds transform to form particles in the air. Our findings help explain the role of these reactions in pollution and provide tools to improve predictions for cleaner air and better climate policies.

We constructed a box model to evaluate the isotope effects of atmosphere–snow water vapor exchange at Dome A, Antarctica. The results show clear and invisible diurnal changes in surface snow isotopes under summer and winter conditions, respectively. The model also predicts that the annual net effects of atmosphere–snow water vapor exchange would be overall enrichments in snow isotopes since the effects in summer appear to be greater than those in winter at the study site.

The study introduces a novel chemical mechanism for explicitly tracking oxygen isotope transfer in oxidized reactive nitrogen and odd oxygen using the Regional Atmospheric Chemistry Mechanism, version 2. This model enhances our ability to simulate and compare oxygen isotope compositions of reactive nitrogen, revealing insights into oxidation chemistry.

A seasonal analysis of the nitrogen isotopes of atmospheric nitrate over the remote Southern Ocean reveals that similar natural NOx sources dominate in spring and summer, while winter is representative of background-level conditions. The oxygen isotopes suggest that similar oxidation pathways involving more ozone occur in spring and winter, while the hydroxyl radical is the main oxidant in summer. This work helps to constrain NOx cycling and oxidant budgets in a data-sparse remote marine region.

Atmospheric nitrate has an important impact on human and ecosystem health. We evaluated atmospheric nitrate formation pathways in the northeastern US utilizing oxygen isotope compositions, which indicated a significant difference between the phases of nitrate (i.e., gas vs. particle). Comparing the observations with model simulations indicated that N2O5 hydrolysis chemistry was overpredicted. Our study has important implications for improving atmospheric chemistry model representation.

Nitrate is a critical component of the atmosphere that degrades air quality and ecosystem health. We have investigated the nitrogen isotope compositions of nitrate from deposition samples collected across the northeastern United States. Spatiotemporal variability in the nitrogen isotope compositions was found to track with nitrate formation chemistry. Our results highlight that nitrogen isotope compositions may be a robust tool for improving model representation of nitrate chemistry.

The discovery of polar subglacial lakes, rivers and streams has opened a new frontier of science within a short span. We present a new environmentally friendly approach to study subglacial reservoirs based on the concept of freezing-in instrumented probes carrying a tethering power-signal cable. In January 2022, the probe was successfully tested in East Antarctica: it reached the base of the ice sheet and returned to the ice surface with samples of melted water from the basal ice.

Atmospheric ammonia and its products are a significant source of urban haze and nitrogen deposition. We have investigated the seasonal source contributions to a mid-sized city in the northeastern US megalopolis utilizing geospatial statistical analysis and novel isotopic constraints, which indicate that vehicle emissions were significant components of the urban-reduced nitrogen budget. Reducing vehicle ammonia emissions should be considered to improve ecosystems and human health.

The nitrogen (N) isotopic composition of atmospheric nitrate in the Southern Ocean (SO) marine boundary layer (MBL) reveals the importance of oceanic alkyl nitrate emissions as a source of reactive N to the atmosphere. The oxygen isotopic composition suggests peroxy radicals contribute up to 63 % to NO oxidation and that nitrate forms via the OH pathway. This work improves our understanding of reactive N sources and cycling in a remote marine region, a proxy for the pre-industrial atmosphere.

Short summary
The deposition and preservation of NO3− across East Antarctica was investigated. On the coast, dry deposition contributes 27–44 % of the NO3− fluxes, and the linear relationship between NO3− and snow accumulation rate suggests a homogeneity of atmospheric NO3− levels. In inland snow, a relatively weak correlation between NO3− and snow accumulation was found, indicating that NO3− is mainly dominated by post-depositional processes. The coexisting ions are generally less influential on snow NO3−.
