Abstract Geomorphic evidence of former glaciation in the high Drakensberg southern Africa has proven controversial, with conflicting glacial and non‐glacial interpretations suggested for many landforms. This paper presents new geomorphological, sedimentological micromorphological data, glacier mass‐balance modelling a site Leqooa Valley, eastern Lesotho, preserving what are considered to be moraines niche that existed during Last Glacial Maximum (LGM). The geomorphology macro‐sedimentology...
Abstract Microstructures, including crystallographic fabric, within the margin of streaming ice can exert strong control on flow dynamics. To characterize a natural setting, we retrieved three cores, two which reached bed, from flank Jarvis Glacier, eastern Alaska Range, Alaska. The core sites lie ~1 km downstream source, with abundant water present in extracted cores and at base glacier. All exhibit dipping layers, combination debris bands bubble-free domains. Grain sizes coarsen average...
It is widely believed that the last glaciers in British Isles disappeared at end of Younger Dryas stadial (12.9–11.7 cal. kyr BP). Here, we use a glacier–climate model driven by data from local weather stations to show for first time developed during Little Ice Age (LIA) Cairngorm Mountains. Our forced contemporary conditions realistic difference mean annual air temperature −1.5°C and an increase precipitation 10%, confirmed sensitivity analyses. These results are supported presence small...
Abstract The reconstruction of former mountain glaciers has long been used to examine the implications rapid climate shifts, for example at last glacial–interglacial transition, and evaluating asynchronous behaviour compared with mid‐latitude ice sheets during Late Quaternary. Glacier also as a source palaeoclimatic information, based on recognition empirical relationships between climate. This paper reviews application recently revised method glacier (Carr Coleman, 2007 ), around...
Abstract. The release of legacy contaminants such as fallout radionuclides (FRNs) in response to glacier retreat is a process that has received relatively little attention date, yet may have consequences source secondary contamination glaciers melt and down-waste warming climate. presence FRNs glacier-fed catchments poorly understood comparison other contaminants, there now emerging evidence from multiple regions the global cryosphere for substantially augmented FRN activities cryoconite....
.Considerable Quaternary environmental reconstruction for the high Drakensberg is based on geomorphological and sedimentological work undertaken along northern aspects of Sekhokong mountain range eastern Lesotho. Given that no previous investigations have focused southern aspects, this paper documents observed geomorphology provides a more complete palaeo‐environmental picture range. Data morphology, sedimentology micromorphology two linear debris ridges are presented. It demonstrated most...
Google Earth has been part of most geoscientists' computer (and mobile) desktops for a decade, and this year Professional become freely available to all with universal license key. Many users are still, however, not aware the full potential that it can offer across range teaching research areas in geosciences. Here pragmatic look is taken at some current key uses terms resources applications how they help training educational roles
Abstract Wind-driven snow redistribution can increase the spatial heterogeneity of accumulation on ice caps and sheets, may prove crucial for initiation survival glaciers in areas marginal glaciation. We present a snowdrift model (Snow_Blow), which extends improves Purves, Mackaness Sugden (1999, Journal Quaternary Science 14, 313–321). The calculates variations relative that result from topography, using digital elevation (DEM) wind direction as inputs. Improvements include flux routing...
.Although snow is known to influence landform genesis and distribution, the spatial associations between landforms within particular cold regions has received limited research attention. We present a case study from high Drakensberg of southern Africa, comparing contemporary pattern longest‐lasting cold‐season patches with distribution patterns active relic region landforms. Two 30 m resolution sets TM images dated 3 19 August 1990 DEM were used demonstrate geographic trends patch depletion...
Relict landforms provide a wealth of information on the evolution modern landscape and climate change in past. To improve understanding origin development these we need better spatial measurements across variety scales. This can be challenging using conventional surveying techniques due to difficulties landform recognition ground (e.g. weak visual/topographic expression) spatially variable areas interest. Here explore appropriateness existing remote sensing datasets (aerial LiDAR aerial...
Abstract Only a small area of the Australian mainland was glaciated during Pleistocene, whereas periglacial deposits are far more common, indicating that cold environments were extensive and major influence on landscape evolution. Here we identify representative low-elevation examples scree slopes frost action, together with fans valley fills, pronounced erosion cycles Pleistocene. To date deposits, explore approaches using radiocarbon, optically stimulated luminescence, profile dating...
