The AA. have studied a 33.7 m deep ice core from a small polythermal Scandinavian ice cap to determine whether it is possible to recover pre-20th century climatic information from the glacier. Results demonstrate that ice cores from glaciers

The AA. report the first results of an on-going study carried out on a 22.5 m ice core recovered from this ice cave, and preserved due to unusual climate and permafrost conditions within the cave. Approximately 200 ice layers have been identified
by visual examination. Ice crystallographic analyses indicate a steady growth of ice crystals with depth and there is no sign of deformation. C 14 dates on wood-related samples collected from a natural vertical exposure of the ice block indicate that the ice
The aim of this paper is to illustrate and describe the meltwater features associated with this expanded Antarctic Ice Sheet that overrode the Transantarctic Mountains. The AA. start by outlining the pattern and process of the long-term landscape
The Little Ice Age : re-evaluation of an evolving concept

This review focuses on the development of the Little Ice Age as a glaciological and climatic concept, and evaluates its current usefulness in the light of new data on the glacier and climatic variations of the last millennium and of the Holocene
. It is concluded that the concept of a Little Ice Age will remain useful only by : continuing to incorporate the temporal and spatial complexities of glacier and climatic variations as they become better known; reflecting improved understanding of the Earth
Climate oscillations as recorded in Svalbard ice core δO 18 records between AD 1200 and 1997

The AA. apply 2 different time series analytical tools to δ O 18 records from 2 Svalbard ice cores. One ice core is from Lomonosovfonna at 1250 m a.s.l. and the other from Austfonna at 750 m a.s.l. These cores are estimated to cover at least
. This reconstruction is also compared with two multi-millennial temperature proxy records from northern Fennoscandia as well as a Northern Hemisphere composite tree-ring chronology regarding the postulated periods such as the Medieval Warm Period and the Little Ice Age.
Norway and New Zealand both experienced recent glacial advances, commencing in the early 1980s and ceasing around 2000, which were more exensive than any other since the end of the Little Ice Age. Common to both countries, the positive glacier
