A method for surveying the condition of extensive walking track systems. Landscape and Urban Planning, 2005 (Ref: 12730)
Category 1: Peer-reviewed literature

Atrialwas undertaken of two techniques for assessing the physical condition ofwalking tracks (trails) over extended distances. A distance-based technique, in which categorical measurements were made at regular spatial intervals, proved to be sufficiently … reliable to warrant further development.

Antarctic temperatures over the past two centuries from ice cores. Geophysical Research Letters, 2006 (Ref: 12668)
Category 1: Peer-reviewed literature

We present a reconstruction of Antarctic mean surface … temperatures over the past two centuries based on water … stable isotope records from high-resolution, precisely dated … ice cores. Both instrumental and reconstructed temperatures … indicate large interannual to decadal scale variability…

Insignificant change in Antarctic snowfall since the International Geophysical Year. Science, 2006 (Ref: 12647)
Category 1: Peer-reviewed literature

Antarctic snowfall exhibits substantial variability over a range of time scales, with consequent … impacts on global sea level and the mass balance of the ice sheets. To assess how snowfall has … affected the thickness of the ice sheets in Antarctica and to provide an extended perspective…

Ice-core-based Antarctic temperature reconstruction. Abstracts of the SCAR Open Science Conference, Hobart, 12-14 July 2006., 2006 (Ref: 12549)
Category 3: Abstract

Most of what has been said about modern Antarctic climate change is based on studies of … meteorological observations that extend back the 1950s. Most attention to Antarctic ice core … records is focused on the timescale of glacial-interglacial cycles.

Solar forcing of the polar atmosphere. Annals of Glaciology, 2005 (Ref: 12350)
Category 1: Peer-reviewed literature

ABSTRACT. We present highly resolved, annually dated, calibrated proxies for atmospheric circulation … from several Antarctic ice cores (ITASE (International Trans-Antarctic Scientific Expedition), Siple … Dome, Law Dome)…

Snow chemistry across Antarctica Annals of Glaciology, 2005 (Ref: 12349)
Category 1: Peer-reviewed literature

An updated compilation of published and new data of major-ion (Ca, Cl, K, Mg, Na, NO3, SO4) and methylsulfonate (MS) concentrations in snow from 520 Antarctic sites is provided by the … national ITASE (International Trans-Antarctic Scientific Expedition) programmes of Australia, Brazil, China…

Ice core evidence of 200 years of Antarctic climate change and its connections with the Southern Annular Mode West Antarctic Ice Sheet (WAIS) Workshop, Virginia. 29 September - 2 October, 2004. NASA/NSF., 2004 (Ref: 12016)
Category 3: Verbal presentation

A sparse network of meteorological observations in Antarctica extends back only to the late 1950s, making it difficult to characterize Antarctica's climate behavior in the context of natural climate variability and global warming. We show that composites of stable isotope (dD and d18O)…
