2. The formation of vertical edges on Antarctic moss peat banks

   Moss peat banks, which can be up to 3 m deep, greater than 2500 m2 in area, and up to 5000 yr old, occur in the Antarctic. Radiocarbon dates show […]

3. Late Mesozoic sedimentation in the northern Antarctic Peninsula and its relationship to the southern Andes

   Two distinct phases of island-are evolution are recognized in late Mesozoic sedimentary rocks of the northern Antarctic Peninsula. During late Jurassic (Kimmeridgian-Tithonian) times, alternating radiolaria-rich mudstones and ash-fall tuffs were […]

4. Lacustrine deltas in a Mesozoic alluvial sequence from Camp Hill, Antarctica

   Sedimentary rocks of late Mesozoic age exposed at Camp Hill, northern Antarctic Peninsula, are associated with calc‐alkaline volcanic rocks. They represent deposition on a fault‐controlled floodplain, with marginal alluvial fans, […]

7. Inter-annual isotopic niche segregation of wild humboldt penguins through years of different El Niño intensities

   The Humboldt Current System presents high interannual variability, influenced by the El Niño Southern Oscillation (ENSO), whose implications in wildlife are not fully understood. We studied the isotopic niche of […]

8. Zooplankton and micronekton respond to climate fluctuations in the Amundsen Sea polynya, Antarctica

   The vertical migration of zooplankton and micronekton (hereafter ‘zooplankton’) has ramifications throughout the food web. Here, we present the first evidence that climate fluctuations affect the vertical migration of zooplankton […]

9. Diurnal variations in mean volume backscattering strength of an Antarctic krill (Euphausia superba) patch

   A series of acoustic transects and quantitative net hauls was made in a large patch of Antarctic krill (Euphausia superba) just north of South Georgia. The krill went through a […]

10. Seasonal microbial activity in Antarctic freshwater lake sediments

    Seasonal fluctuations in population numbers and activity were monitored in bottom sediments of oligotrophic Moss Lake, mesotrophic Heywood Lake and eutrophic Amos Lake on Signy Island, South Orkney Islands, during […]

11. Ionospheric troughs in Antarctica

    We report here the first observations of the dynamics of both the mid-latitude and high-latitude troughs made by the Advanced Ionospheric Sounder (AIS) at Halley Station, Antarctica (76° S, 27° […]

12. State of balance of the ice sheet in the Antarctic Peninsula

    Data from ice rises on the east coast of the Antarctic Peninsula can be interpreted as showing that the ice is thinning at rates of up 0.5 m a−1. However, […]
