  • Utilities, land-use change, and urban development : brownfield sites as cold-spots of infrastructure networks in Berlin
  • Berlin ; Consumption ; Deindustrialization ; Facilities ; Germany ; Infrastructure ; Land use ; Segregation ; Spatial differentiation ; Supplying ; Urban area ; Urban development
  • Drawing on recent research into the spatial strategies of utility companies, after liberalisation and privatisation, the A. identifies disused industrial sites as cold-spots of infrastructure systems where energy and water consumption has recently
  • Greenhouse impact on cold-climate ecosystems and landscapes

  • A review of aeolian transport processes in cold environments
  • Boundary layer ; Canada ; Cold area ; Eolian deflation ; Eolian erosion;Wind erosion ; Eolian features ; Eolian transport ; Ice ; Model ; Snow ; Soil moisture ; Vegetation
  • This article reviews what little is known of the boundary layer and surficial controls on aeolian activity in contemporary cold humid settings. Field and simulation work on the boundary layer and surface controls, which include wind shear velocity
  • Landscapes of cold-centred Late Wisconsinan ice caps, Arctic Canada
  • Arctic Ocean;Arctic Region ; Canada ; Cold area ; Geomorphology ; Glacial features ; Glaciology ; Ice sheet;Ice cap;Inlandsis ; Meltwater ; Model ; Quaternary ; Wisconsinan
  • Uplands of the Canadian Arctic Islands supported Late Wisconsinan ice caps that developed two landscape zones reflecting basal thermal conditions regulated by long-sustained ice flow patterns. Central cold-based zones protected older glacial
  • Fluvial suspended sediment transport from cold and warm-based glaciers in Svalbard
  • Arctic Region ; Cold area ; Fluvioglacial features ; Glacier ; Meltwater ; Model ; Regression analysis ; Suspended load ; Svalbard
  • This paper presents a quantitative comparison of proglacial suspended sediment transport dynamics in three contrasting arctic glacier basins : one largely cold-based glacier (Austre Brøggerbreen), one largely warm-based glacier (Finsterwalderbreen
  • Fluvial suspended sediment transport from cold and warm-based glaciers in Svalbard
  • Arctic Region ; Cold area ; Fluvioglacial features ; Glacier ; Model ; Quantitative analysis ; Regression analysis ; Sediment transport ; Suspended load ; Svalbard
  • This paper presents a quantitative comparison of proglacial suspended sediment transport dynamics in 3 contrasting arctic glacier basins. The study sites include a largely cold-based glacier, a largely warm-based glacier and an intermediate type
  • The endokarstic erosion of marble in cold climates : Corbel revisited
  • Carbonate dissolution ; Carbonate rock ; Cave ; Cold area ; Europe ; Glacial cycle ; Karst ; Karstification ; Quaternary ; Scandinavia ; Temperature
  • developed considerably. Corbel concluded that ‘karstification proceeds much faster in a cold than in a warm climate’, based on the knowledge that the solubilities of both CO2 and CaCO3 increase with lower temperature, without realizing that because cave
  • Geomorphological aspects of road construction in a cold environment, Finland
  • Cold area ; Finland ; Freezing ; Geotechnics ; Glacial features ; Periglacial features ; Permafrost ; Road ; Road infrastructure ; Snow
  • This paper gives examples of geomorphic elements affecting road construction in a cold environment : eskers, drumlins, plains of late and postglacial glaciolacustrine and marine sediments, mires, steep rock cliffs, river channels and ice-dams
  • Hydrology and dynamics of a polythermal (mostly cold) High Arctic glacier
  • Arctic Region ; Canada ; Cold area ; Ellesmere ; Glacial flow ; Glacier ; Glacier dynamics ; Meltwater ; Northwest Territories ; Nunavut ; Polar region ; Thermal regime
  • To improve the understanding of the interactions between hydrology and dynamics in mostly cold glaciers (in which water flow is limited by thermal regime), the AA. analyse short-term (every 2 days) variations in glacier flow in the ablation zone
  • Greenhouse impact on cold-climate ecosystems and landscapes
  • Canada ; Climatic variation ; Cold area ; Europe ; Forest ; Forest fire ; Impact ; Landscape ; Ontario ; Scandinavia
  • This paper's hypothesis is that, just as summer climate warming in Canada has produced dramatic increases in the number and total area of forest fires, so tool will any increase in summer temperatures in Fennoscandia. If this is so, complacency

  • evaporation, including hot and cold desert environments. The review features gypsum in caves, salt pans and limestone walls with sulphur sources ranging from the marine environment to bedrock.
  • in the Alexandra Fjord-Cape Herschel area of east-central Ellesmere Island. Particular emphasis is placed on the influence of bedrock, lithology and mineralogy on the intensity of physical disintegration under cold arid conditions. Preservation of certain remnant
  • weathering features in upland summit areas under cold-based glacial ice is postulated.
  • Geochemical problems of the Antarctic dry areas
  • The dry areas of the Antarctic are extreme deserts. Because of the cold they are not subjected to rainfall and geochemical separations can take place which would be destroyed by flowing water in the more temperate deserts. The distribution
  • Vysné Ruzbachy-najvydatnejsi areal mineralnych vod na Slovensku Vysné Ruzbachy-the most abundant mineral water area in Slovakia
  • The richest area of thermal mineral water of Slovakia has altogether eight main warm springs and some smaller springs with cold chalybeate water. The origin of these waters suppose the autor newly in the Propadska kotlina (Basin) and Levocska
  • Air temperature ; Cold area ; Geochemistry ; Ground ice ; Methodology ; Oxygen 18 ; Palaeoclimatology ; Palaeogeography ; Palaeotemperature ; Permafrost ; Precipitation ; Russia ; Siberia ; Snow
  • The AA. propose to use oxygen isotope composition (δ18O) of ground ice (ice cement, as well as segregated ice) for reconstruction of cold-season paleotemperature (Tc) in permafrost areas. The term cold season refers to the period when precipitation
