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 […]
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 […]
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 […]
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. […]
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 […]
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 […]
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 […]
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 […]
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 […]
