1. Orbitally induced oscillations in the East Antarctic ice sheet at the Oligocene/Miocene boundary

   Between 34 and 15 million years (Myr) ago, when planetary temperatures were 3–4 °C warmer than at present and atmospheric CO2 concentrations were twice as high as today1, the Antarctic […]

2. Modelling Southern Ocean krill population dynamics: biological processes generating fluctuations in the South Georgia ecosystem

   Variability is a key feature of the pelagic ecosystems of the Southern Ocean and an important aspect of the variation is fluctuation in the abundance of krill Euphausia superba Dana, […]

3. CO2 fluxes among different vegetation types during the growing season in Marguerite Bay (Antarctic Peninsula)

   The Antarctic Peninsula has experienced a strong climate warming trend of + 0.53 °C (mean annual air temperature) over the last 50 years. In the Polar Regions, changes in vegetation […]

4. Use of Deschampsia antarctica for nest building by the kelp gull in the Argentine Islands area (maritime Antarctica) and its possible role in plant dispersal

   During the last 50 years, the western coast of the Antarctic Peninsula and adjacent archipelagos, also known as the maritime Antarctic, has experienced notable climate warming. As a result, expansion […]

5. Provenance and sex ratio of black-browed albatross, Thalassarche melanophrys, breeding on Campbell Island, New Zealand

   Small numbers of Black-browed Albatross, Thalassarche melanophrys, breed on Campbell Island, New Zealand. Their dark brown irises had previously been used to distinguish them from the more numerous Campbell Albatross, […]

6. Seasonal inflow of warm water onto the southern Weddell Sea continental shelf, Antarctica

   To capture the austral summer to winter transition in water mass properties over the southern Weddell Sea continental shelf and slope region, 19 Weddell seals were tagged with miniaturized conductivity–temperature–depth […]

7. Simultaneous measurements of the O2(¹Δ) and O2(¹Σ) Airglows and ozone in the daytime mesosphere

   We report simultaneous measurements of the O2(¹Δ) and O2(¹Σ) airglow volume emission rate profiles in the daytime mesosphere. We use these measurements to derive ozone concentrations separately from each airglow. […]

9. An hour of bright white light in the early morning improves performance and advances sleep and circadian phase during the Antarctic winter

   Previous work has demonstrated that exposure to an hour of bright light in the morning and the evening during the Polar winter has beneficial effects on circadian phase. This study […]

10. The role of crustal and mantle sources in the genesis of granitoids of the Antarctic Peninsula and adjacent crustal blocks

    Magmatic rocks from the Antarctic Peninsula show marked variations in isotope composition, which reflect changes in the geodynamic evolution of the peninsula through time. Most Antarctic Peninsula granitoids formed as […]

11. The excitation of convection in the cusp region as observed by the SuperDARN radars

    SuperDARN observations from the interval 1330 UT to 1500 UT, 17 April 1996, are presented. During this interval, five radars covered 12 hours of magnetic local time on the dayside, […]

12. Atmospheric water vapor over Antarctica derived from Special Sensor Microwave/Temperature 2 data

    In polar regions, satellite microwave radiometry has not been successful in measuring the total water vapor (TWV) in the atmosphere. The difficulties faced in these regions arise from the very […]
