1. 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 […]

2. 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 […]

3. 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 […]

4. 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.

5. Meteor radar vertical wind observation biases and mathematical debiasing strategies including the 3DVAR+DIV algorithm

   Meteor radars have become widely used instruments to study atmospheric dynamics, particularly in the 70 to 110 km altitude region. These systems have been proven to provide reliable and continuous […]

6. New mitogenomes in deep-water endemic Cocculinida and Neomphalida shed light on lineage-specific gene orders in major gastropod clades

   Gastropoda is the most speciose class in Mollusca, the second largest animal phylum, whose internal relationships remain largely unsettled, partly due to the insufficient data from key deep-water endemic lineages, […]

7. Observations of Modified Warm Deep Water beneath Ronne Ice Shelf, Antarctica, from an Autonomous Underwater Vehicle

   Filchner-Ronne Ice Shelf (FRIS) is the world’s largest ice shelf by volume. It helps regulate Antarctica’s contribution to global sea level rise, and water mass transformations within the sub-ice-shelf cavity […]

8. Modeling the effects of drift shell splitting in two case studies of simultaneous observations of substorm-driven Pi1B and IPDP-type EMIC waves

   Intervals of Pulsations of Diminishing Periods (IPDPs) are a subtype of Electromagnetic Ion Cyclotron (EMIC) waves that can be triggered by substorm onset. Pi1B waves are Ultra Low Frequency (ULF) […]

9. Divergent foraging habitat preferences between summer-breeding and winter-breeding Procellaria petrels

   Foraging niche specialisation is thought to occur when different members of speciose communities divide resources in either time or space. Here we compared habitat preferences of the congeneric Grey Petrel […]

10. Seabird and seal responses to the physical environment and to spatio-temporal variation in the distribution and abundance of Antarctic krill at South Georgia, with implications for local fisheries management

    We used 22 years of seasonally and spatially consistent monitoring data to explore marine predator–prey numerical response relationships. Specifically, we tested whether indices of offspring performance (e.g. offspring mass near the […]

11. Influence of marine vertebrates on organic matter, phosphorus and other chemical element levels in Antarctic soils

    The presence of marine vertebrates in dense reproductive colonies and other aggregations contributes to the input of organic matter and nutrients into the local environment and it is believed that […]

12. Temporal variability of quasilinear pitch-angle diffusion

    Kinetic wave-particle interactions in Earth’s outer radiation belt energize and scatter high-energy electrons, playing an important role in the dynamic variation of the extent and intensity of the outer belt. […]
