1. Interannual variability of the 12-hour tide in the mesosphere and lower thermosphere in 15 years of meteor-radar observations over Rothera (68° S, 68° W)

   The solar tides of the mesosphere and lower thermosphere (MLT) show great variability on timescales of days to years, with significant variability at interannual timescales. However, the nature and causes […]

2. High mid-Holocene accumulation rates over West Antarctica inferred from a pervasive ice-penetrating radar reflector

   Understanding the past and future evolution of the Antarctic Ice Sheet is challenged by the availability and quality of observed paleo-boundary conditions. Numerical ice-sheet models often rely on these paleo-boundary […]

3. On the evolution of an ice shelf melt channel at the base of Filchner Ice Shelf, from observations and viscoelastic modeling

   Ice shelves play a key role in the stability of the Antarctic Ice Sheet due to their buttressing effect. A loss of buttressing as a result of increased basal melting […]

4. 130 years of heavy metal pollution archived in the shell of the intertidal dog whelk, Nucella lapillus (Gastropoda, Muricidae)

   Heavy metals in coastal waters are a great environmental concern in the North Sea since the middle of the 20th century. Regulatory efforts have led to a significant reduction in […]

5. Ionospheric D region: VLF‐measured Electron Densities compared with Rocket‐Based FIRI‐2018 Model

   Ground-based very low frequency (VLF) radio propagation in the Earth-ionosphere waveguide has enabled extensive electron number densities in the D region of the Earth’s ionosphere to be determined, by day […]

6. Communities of culturable freshwater fungi present in Antarctic lakes and detection of their low-temperature-active enzymes

   We evaluated the diversity and enzymatic activities of culturable fungi recovered from cotton baits submerged for 2 years in Hennequin Lake, King George Island, and from benthic biofilms in Kroner […]

7. Intronic primers reveal unexpectedly high major histocompatibility complex diversity in Antarctic fur seals

   The major histocompatibility complex (MHC) is a group of genes comprising one of the most important components of the vertebrate immune system. Consequently, there has been much interest in characterising […]

8. Three decades of remote sensing subarctic vegetation in northern Russia: A case study in science diplomacy

   The vegetation at and beyond the northern edge of the world’s boreal forest plays an important though imperfectly understood role in the climate system. This is particularly true within Russia, […]

9. Control of Antarctic phytoplankton community composition and standing stock by light availability

   Southern Ocean phytoplankton are especially subjected to pronounced seasonal and interannual changes in light availability. Although previous studies have examined the role of light in these environments, very few combined […]

10. Potential for redistribution of post‐moult habitat for Eudyptes penguins in the Southern Ocean under future climate conditions

    Anthropogenic climate change is resulting in spatial redistributions of many species. We assessed the potential effects of climate change on an abundant and widely distributed group of diving birds, Eudyptes […]

11. Surface snow bromide and nitrate at Eureka, Canada in early spring and implications for polar boundary layer chemistry

    This study explores the role of snowpack in polar boundary layer chemistry, especially as a direct source of reactive bromine (BrOx = BrO + Br) and nitrogen (NOx = NO + NO2) in the Arctic springtime. Surface snow […]

12. Underwater Ice Boosts Production of the World Oceans’ Densest Waters

    Waters cooled below freezing point adjacent to Cape Darnley, Antarctica generate subsurface ice and produce dense waters that flood the global ocean abyss.
