1. Tropospheric clouds in Antarctica

   Compared to other regions, little is known about clouds in Antarctica. This arises in part from the challenging deployment of instrumentation in this remote and harsh environment and from the […]

2. Holocene deglacial history of the northeast Antarctic Peninsula – A review and new chronological constraints

   The northeast Antarctic Peninsula (NEAP) region is currently showing signs of significant environmental change, evidenced by acceleration of glacial retreat and collapse of both Larsen-A and -B ice shelves within […]

3. Revisiting the lower stratospheric water vapour trend from the 1950s to 1970s

   Previous work showed a near-continuous increase in stratospheric water vapour between the 1950s and 1990s from a variety of instruments, without recourse to fits between instruments. We reassess the trend […]

4. Rapid climate change: lessons from the recent geological past

   Rapid, or abrupt, climate change is regarded as a change in the climate system to a new state following the crossing of a threshold. It generally occurs at a rate […]

5. Seasonal patterns of prolactin and corticosterone secretion in an Antarctic seabird that moults during reproduction

   In avian species that have evolved life-history strategies wherein molt and breeding overlap, there are potential conflicts between the regulatory roles of baseline prolactin and corticosterone in parental care (positive) […]

6. Cellular biomarkers to elucidate global warming effects on Antarctic sea urchin Sterechinus neumayeri

   Global warming is a reality and its effects have been widely studied. However, the consequences for marine invertebrates remain poorly understood. Thus, the present study proposed to evaluate the effect […]

7. Abrupt changes in high-latitude nutrient supply to the Atlantic during the last glacial cycle

   The supply of nutrients to the low-latitude thermocline is largely controlled by intermediate- depth waters formed at the surface in the high southern latitudes. Silicic acid is an essential macronutrient […]

8. Evidence for hydrothermal venting and sediment volcanism discharged after recent short-lived volcanic eruptions at Deception Island, Bransfield Strait, Antarctica

   The results of a combined geophysical and geochemical research programme on Deception Island, an active volcano at 62degrees43’S, 60degrees57’W in Bransfield Strait (Antarctica), are presented. Ultrahigh-resolution acoustic data obtained with […]

9. Mitochondrial DNA sequence evidence supporting the recognition of a new North Atlantic Pseudostichopus species (Echinodermata : Holothuroidea)

   A new species of the synallactid sea cucumber genus Pseudostichopus is described, P. aemaulatus sp. nov., based on genetic (DNA sequences of the mitochondrial gene Cytochrome Oxidase I [COI] gene) […]

10. Differences in ground-observed chorus in geomagnetic storms with and without enhanced relativistic electron fluxes

    It has been suggested that whistler mode chorus waves play a role in the acceleration and loss of radiation belt electrons during geomagnetic storms. In a previous statistical study of […]

11. Ground observations of chorus following geomagnetic storms

    [1] It has been suggested that whistler mode chorus waves play a role in acceleration and loss of radiation belt electrons during geomagnetic storms. In this paper we present data […]

12. Frazil ice formation in an ice shelf water plume

    [1] We present a model for the growth of frazil ice crystals and their accumulation as marine ice at the base of Antarctic ice shelves. The model describes the flow […]
