1. The exploitation of Antarctic minerals

   Exploitation of minerals either from continental shelves or land areas free of ice has yet to take place in the Antarctic. The paper considers pressures, commercial, strategic, and possible depletion […]

4. Foraging energetics of Grey-headed Albatrosses Diomedea chrysostoma at Bird Island, South Georgia

   At‐sea metabolism (CO2 production) and water turnover of six breeding Grey‐headed Albatrosses Diomedea chrysostoma were measured, using the doubly labelled water method, at Bird Island, South Georgia, Mean food consumption […]

5. Lipid in an arctic food chain: Calanus, Bolinopsis, Beroe

   The zooplankton of the fjords of Svalbard in late summer is dominated by copepodites of Calanus glacialis (JASCHNOV). These are consumed by, among others, the lobate ctenophore Bolinopsis infundibulum (O.F. […]

6. Spatial and temporal scales matter when assessing the species and genetic diversity of springtails (Collembola) in Antarctica

   Seven species of springtail (Collembola) are present in Victoria Land, Antarctica and all have now been sequenced at the DNA barcoding region of the mitochondrial cytochrome c oxidase subunit I […]

7. Energy flow in growth and production

   Growth involves two flows of energy: the chemical energy in the monomers used to construct the macromolecules that comprise tissue (proteins, nucleic acids, lipid membranes), and the metabolic energy used […]

8. ATAT 1.1, the Automated Timing Accordance Tool for comparing ice-sheet model output with geochronological data

   Earth’s extant ice sheets are of great societal importance given their ongoing and potential future contributions to sea-level rise. Numerical models of ice sheets are designed to simulate ice-sheet behaviour […]

9. Variability and change in the west Antarctic Peninsula marine system: research priorities and opportunities

   The west Antarctic Peninsula (WAP) region has undergone significant changes in temperature and seasonal ice dynamics since the mid-twentieth century, with strong impacts on the regional ecosystem, ocean chemistry and […]

10. Review of the accomplishments of midlatitude Super Dual Auroral Radar Network (SuperDARN) HF radars

    The Super Dual Auroral Radar Network (SuperDARN) is a network of high-frequency (HF) radars located in the high- and mid-latitude regions of both hemispheres that is operated under international cooperation. […]

11. How well can we estimate Pedersen conductance from the THEMIS white-light all-sky cameras?

    We show that a THEMIS (Time History of Events and Macroscale Interactions during Substorms) white‐light all‐sky imager (ASI) can estimate Pedersen conductance with an uncertainty of 3 mho or 40%. […]

12. New recombinant cold-adapted and organic solvent tolerant lipase from psychrophilic Pseudomonas sp. LSK25, isolated from Signy Island Antarctica

    In recent years, studies on psychrophilic lipases have become an emerging area of research in the field of enzymology. The study described here focuses on the cold-adapted organic solvent tolerant […]
