1. Dust and sea salt variability in central East Antarctica (Dome C) over the last 45 kyrs and its implications for southern high-latitude climate

   A detailed record of non-sea-salt calcium, a proxy for dust, and sea-salt sodium, a proxy for sea salt, covering the last 45 kyr is presented. It shows that in the […]

2. Nitrate in Greenland and Antarctic ice cores: a detailed description of post-depositional processes

   A compilation of nitrate (NO(3)(-)) data from Greenland has shown that recent NO(3)(-) concentrations reveal a temperature dependence similar to that seen in Antarctica. Except for sites with very low […]

3. Vertical resolution of oversampled limb-sounding measurements from satellites and aircraft

   Measurements of trace gases by remote sensors which observe the atmospheric limb have a natural verticalresolution of 2–. With a typical field of view this becomes 3–. Oversampling, combined with […]

4. Genetic diversity of algal and fungal partners in four species of Umbilicaria (lichenized ascomycetes) along a transect of the Antarctic Peninsula

   Lichens from the genus Umbilicaria were collected across a 5,000-km transect through Antarctica and investigated for DNA sequence polymorphism in a region of 480–660 bp of the nuclear internal transcribed […]

7. Making data a first class scientific output : data citation and publication by NERC’s Environmental Data Centres

   The NERC Science Information Strategy Data Citation and Publication project aims to develop and formalise a method for formally citing and publishing the datasets stored in its environmental data centres. […]

8. Inner radiation belt electron lifetimes due to whistler-induced electron precipitation (WEP) driven losses

   Wave-particle interactions driven by whistler mode waves in the inner Van Allan belt is an important loss process for the energetic electrons found in this region. In this paper we […]

9. D region reflection height modification by whistler-induced electron precipitation

   We examine the electron density profile expected in the lower ionosphere due to a 0.2-s whistler-induced electron precipitation (WEP) burst with experimentally determined properties. The ionization rate in the lower […]

10. Fracture of Antarctic shelf ice

    We have investigated the fracture of Antarctic shelf ice core using two fracture mechanics test methods: the chevron-notched short-rod specimen loaded in tension and the chevron-notched round-bar specimen loaded in […]

11. Acceleration of Pine Island and Thwaites Glaciers, West Antarctica

    Recent satellite investigations revealed that in the 1990s the grounding line of Pine Island and Thwaites Glaciers, West Antarctica, retreated several km, the ice surface on the interior of the […]

12. Aptian to Coniacian (Early-Late Cretaceous) palynostratigraphy of the Gustav Group, James Ross Basin, Antarctica

    The GustavGroup of the James Ross Basin, Antarctic Peninsula, forms part of a major Southern Hemisphere Cretaceous reference section. Palynological data, chiefly from dinoflagellate cysts, integrated with macrofaunal evidence and […]
