The concentration of methane in air bubbles within permafrost was sampled from both alluvial deposits and ice wedges in Eastern Siberia. The values of methane concentration were as high as 6000 ppmv in both frozen soil and ice wedges. The anti
Corporations in the 1980s, explores the reasons why policy should have taken a significant change with the introduction of the Single Regeneration Budget and looks at the elements both of continuity and change since 1997.
In this work, the AA. apply the techniques developed for determining basin-wide sediment generation rates in small basins to both the entire Yuma Wash drainage and to smaller sub-basins of the Wash. Tracing nuclide concentrations in sediment along
reflect both upland sediment generation and the long-term effects of sediment storage and reworking.
The question of how much progress has been made in any sphere of life calls for the interrogation of both the meanings and measurement of progress. This applies to discussions on progress made by scientific disciplines. For a discipline
The A. speaks to debates amongst geographers and media scholars about the communities that television constructs in both real and virtual spaces. Analysis turns to a 1999 episode of Fox TV's that featured the mysterious disappearances of 31 women.

This paper examines frozen fine-grained soils, mainly of Pleistocene and Holocene age, that are distributed along the Arctic coast at the surface and which contain soluble salts. Salinization is determined by both the conditions at formation
, which is essentially a combination of frost creep and solifluction. Both terraces and terracettes are part of the periglacial environment and are active under present climatic conditions. - (AJC)
The trends in southern African geomorphology, based on a review of some 1500 journal articles and 11 conference proceedings from both the local Geomorphology Association and Geography Society are reviewed. They are contrasted with developments
This research investigates how human disturbance has affected foredune vegetation of the Georgia Sea Islands (GSI) in the United States. Both two-factor analysis of variance, ANOVA, and nonmetric multidimensional scaling, NMS, agree that dunes
Measurements of turf-banked solifluction lobes at a site in the Kluane Range, Yukon Territory, are compared to observations made by L.W. Price of similar features located 50 km to the north in the Ruby Range. Both studies show that a threshold depth
in appearance to the rinnenkarren described in the karst literature, are developed on steeply inclined bedrock surfaces while the rock varnish occurs on adjacent, more gently sloping bedrock surfaces. The preservation of both phenomena supports : the idea
and success in broader terms through two New Zealand case studies. The discussion suggests that there were subtle graduations of both administrative and settler success and failure.
Under both (GISS and GFDL) climatic scenarios the self-sufficiency of food production in Poland may be maintened, provided that special adaptational measures are adopted. Among them are : complex organization of rural infrastructure ; the developing
This study examines the relationship between lithology and slope form in an area characterised by a highly varied range of different rock types occurring alongside one another : the Jacupiranga Alkaline Complex. As both the tectonic evolution

The article examines the implicit boundary narratives of both modernization theory and of its counter-discourses and successors. Among the successors, special attention is given to the paradigm of reflexive modernization and its empirical corollary
After a brief section which reviews some recent debates about geography and economics, the second section raises the possibility and implications of geographies in economies. The argument is that economies are doubtly geographical in terms of both
