1. Has the Antarctic Vortex Split before 2002?

   In late September 2002, the Antarctic ozone hole was seen to split into two parts, resulting in large increases in ozone at some stations and the potential for significant modification […]

2. Polar mesosphere summer echo detection using a dynasonde

   We describe a new polar mesosphere summer echo (PMSE) radar system implementation that uses a snow-buried antenna operated with the dynasonde at Halley, Antarctica (76°S), the highest southern latitude at […]

3. Three-dimensional model study of the Antarctic ozone hole in 2002 and comparison with 2000

   An offline 3D chemical transport model (CTM) has been used to study the evolution of the Antarctic ozone hole during the sudden warming event of 2002 and to compare it […]

4. Subglacial imprints of early Gondwana break-up as identified from high resolution aerogeophysical data over western Dronning Maud Land, East Antarctica

   Determining the location and geometry of possible subglacial rifts in western Dronning Maud Land is a key element to address processes leading to early Gondwana break-up. However, previous geophysical investigations […]

5. Tectonic and magmatic patterns in the Jutulstraumen rift (?) region, East Antarctica, as imaged by high-resolution aeromagnetic data

   The Jutulstraumen ice stream in western Dronning Maud Land may conceal a Jurassic continental rift. Delineating the geometry and the magmatic patterns of this inferred glaciated rift in East Antarctica […]

6. Sm–Nd mineral ages and P–T constraints on the pre-Grampian high grade metamorphism of the Slishwood Division, north-west Ireland.

   Granulite-facies metamorphism affecting the Slishwood Division was extreme. Three samples yielded P–T conditions of 15.8, 14, 14.9kbar at 810, 750 and 880°C, respectively. Four Sm–Nd mineral isochrons, defined by granulite-facies […]

7. Age and tectonic significance of the Lassiter Coast Intrusive Suite, Eastern Ellsworth Land, Antarctic Peninsula

   Depleted mantle model ages derived from granitoids of the Lassiter Coast Intrusive Suite, sampled over a wide geographical area in eastern Ellsworth Land, Antarctica, cluster between 1000 Ma and 1200 […]

8. Nematode-specific PCR primers for the 18S small subunit rRNA gene

   A set of polymerase chain reaction primers were designed, which amplify a c. 1 kb fragment of the 18S ribosomal DNA gene, and are specific to the phylum Nematoda. These […]

9. The effects of global climate variability in pup production of Antarctic fur seals

   Climate variability has strong effects on marine ecosystems, with repercussions that range in scale from those that impact individuals to those that impact the entire food web. Climate-induced changes in […]

10. Stable isotopes reveal trophic segregation by sex and age in the southern giant petrel in two different food webs

    We investigated trophic ecology variation among colonies as well as sex- and age-related differences in the diet of the southern giant petrel Macronectes giganteus, a long-lived seabird that is sexually […]

11. Observing the vertical branch of the mesospheric circulation at latitude 60°N using ground-based measurements of CO and H2O

    In this report daily ground-based measurements of vertical profiles of CO and H2O from 2002 are used to trace the vertical movement of air caused by the seasonally varying mean […]

12. The retreat of Jones Ice Shelf, Antarctic Peninsula

    In recent decades, several ice shelves along the Antarctic Peninsula have diminished in size as a result of climate warming. Using aerial photographic, satellite and survey data we document a […]
