1. The thermal limits to life on Earth

   Living organisms on Earth are characterized by three necessary features: a set of internal instructions encoded in DNA (software), a suite of proteins and associated macromolecules providing a boundary and […]

2. Can uncertainties in sea ice albedo reconcile patterns of data-model discord for the Pliocene and 20th/21st centuries?

   General Circulation Model simulations of the mid-Pliocene warm period (mPWP, 3.264 to 3.025 Myr ago) currently underestimate the level of warming that proxy data suggest existed at high latitudes, with […]

3. The spatial structure of Antarctic biodiversity

   Patterns of environmental spatial structure lie at the heart of the most fundamental and familiar patterns of diversity on Earth. Antarctica contains some of the strongest environmental gradients on the […]

4. Latest Cretaceous–earliest Paleogene vegetation and climate change at the high southern latitudes: palynological evidence from Seymour Island, Antarctic Peninsula

   Fluctuations in Late Cretaceous climate were already influencing biotic change prior to the environmental upheaval at the Cretaceous – Paleogene (K–Pg) boundary, but their general nature, magnitude and timing remain […]

5. Longitudinal bio-logging reveals interplay between extrinsic and intrinsic carry-over effects in a long-lived vertebrate

   Carry-over effects have major implications for individual fitness and population and evolutionary dynamics. The strength of these effects is dependent on an individual’s intrinsic performance and the environmental conditions it […]

6. Instantaneous movement of krill swarms in the Antarctic Circumpolar Current

   Antarctic krill are known to have strong swimming capabilities, but direct observations of the speed and direction of krill-swarm movement within their natural environment are rare. We identified and examined […]

7. A statistical approach to determining energetic outer radiation-belt electron precipitation fluxes

   Sub-ionospheric radio-wave data from an AARDDVARK receiver located in Churchill, Canada, is analysed to determine the characteristics of electron precipitation into the atmosphere over the range 3 30 keV precipitation fluxes of […]

8. Climate change and Southern Ocean ecosystems I: How changes in physical habitats directly affect marine biota

   Antarctic and Southern Ocean (ASO) marine ecosystems have been changing for at least the last 30 years, including in response to increasing ocean temperatures and changes in the extent and […]

9. The contribution of the Weddell Gyre to the lower limb of the global overturning circulation

   The horizontal and vertical circulation of the Weddell Gyre is diagnosed using a box inverse model constructed with recent hydrographic sections and including mobile sea ice and eddy transports. The […]

10. Sea ice and the ocean mixed layer over the Antarctic shelf seas

    An ocean mixed-layer model has been incorporated into the Los Alamos sea ice model CICE to investigate regional variations in the surface-driven formation of Antarctic shelf waters. This model captures […]

11. A leg-band for mounting geolocator tags on penguins

    We present a design for a simple, inexpensive leg band for mounting GLS tags on penguins. It causes a low level of injury and can be made from materials and […]

12. Basal roughness of the Institute and Möller Ice Streams, West Antarctica: Process determination and landscape interpretation

    We present a detailed analysis of bed roughness beneath Institute and Möller Ice Streams, west Antarctica, using radio-echo sounding data (RES) acquired in the austral summer of 2010/11. We assess […]
