1. Reconstruction of the fluence of extreme solar particle events registered in cosmogenic proxies

   Extreme solar particle events (ESPEs) are infrequent yet highly potent manifestations of solar activity. These events result in the production of significant amounts of cosmogenic isotopes(CIs): 10Be, 36Cl, and 14C, […]

2. Germination Strategies and Seed Quality of Colobanthus quitensis: Implications for Sustainable Antarctic Ecosystems and Ex Situ Plant Conservation

   The conservation of the Antarctic ecosystem is linked to scientific and tourism activities. The Colección Activa de Plantas Vasculares Antárticas at the Universidad de Concepción aims to help conserve the […]

3. Bioconnection of airborne fungal diversity across the South Atlantic Ocean, sub-Antarctic and South Shetland Islands assessed using DNA metabarcoding

   To better understand the long-distance dispersal of fungi between South America and Antarctica, we assessed aerial fungal diversity based on environmental DNA samples along a South Atlantic transect from Brazil […]

4. Method for Quantification of Fatty Acids in Ice Cores and Sea-Ice Cores Using Liquid Chromatography High-Resolution Mass Spectrometry

   Marine-sourced fatty acids provide a promising new suite of proxies for past sea-ice reconstructions, validated using ice cores from Bouvet Island, Greenland, and Alaska. Despite showing great potential as a […]

5. A Local Meteoric Water Line for Interior Alaska constrains Paleoclimate From 40,000 year old Relict Permafrost

   Anthropogenic climate warming is degrading permafrost across Interior Alaska. Information from past warming events provides long-term perspectives of future trajectories, however, late Quaternary seasonal temperatures are poorly constrained. We established […]

6. The Paleochrono-1.1 probabilistic model to derive a common age model for several paleoclimatic sites using absolute and relative dating constraints

   Past climate and environmental changes can be reconstructed using paleoclimate archives such as ice cores, lake and marine sediment cores, speleothems, tree rings, and corals. The dating of these natural […]

7. A circumpolar review of the breeding distribution and habitat use of the snow petrel (Pagodroma nivea), the world’s most southerly breeding vertebrate

   Knowledge of the spatial distribution of many polar seabird species is incomplete due to the remoteness of their breeding locations. Here, we compiled a new database of published and unpublished […]

8. Active and passive organic carbon fluxes during a bloom in the Southern Ocean (South Georgia)

   The Controls Over Mesopelagic Interior Carbon Storage (COMICS) cruise DY086 took place aboard the RRS Discovery in the South Atlantic during November and December, 2017. Physical, chemical, biogeochemical and biological […]

9. Record-low Antarctic sea ice in 2023 increased ocean heat loss and storms

   Recent Antarctic sea-ice decline is a substantial source of concern, notably the record low in 2023 (ref. 1 ). Progress has been made towards establishing the causes of ice loss […]

10. Direct Geologic Constraints on the Timing of Late Holocene Ice Thickening in the Amundsen Sea Embayment, Antarctica

    Constraining past West Antarctic Ice Sheet (WAIS) change helps validate numerical models simulating future ice sheet dynamics. Following rapid deglaciation during the mid-Holocene, ice near Thwaites Glacier was ∼35 m […]

11. The global mapping of electron precipitation and ionospheric conductance from whistler-mode chorus waves

    Auroral precipitation is the second major energy source after solar irradiation that ionizes the Earth’s upper atmosphere. Diffuse electron aurora caused by wave-particle interaction in the inner magnetosphere (L < […]
