15 lis 2020 · This glacial cirque is shaped on the northern face of the Mulhacén peak (3479 m a.s.l. 37°03′12″N/3°18′41″W), Sierra Nevada, southern Spain. It includes several depositional and erosional glacial landforms that allowed reconstructing its environmental evolution since the last glacial cycle.
21 lis 2017 · Cirques are a common glacial erosive landform present in alpine regions. They are bowl-shaped depressions with a steep headwall and a gently sloping floor, created by an isolated, rotationally flowing glacier, and they periodically contain small climate-sensitive glaciers (e.g. Evans & Cox 1974 ; Porter 2001 ; Brook et al .
26 lip 2020 · Cirques on the Faroe Islands are smaller in length and width and present at lower elevations compared to cirques located in other regions of the world. The timing of glacial occupation in these cirques is not known, and the landforms likely formed over multiple glaciations.
1 paź 2021 · The proglacial area of the Chato Glacier, in one cirque of the Fuegian Andes, presents a particular landform assemblage related to its rapid retreat and downwasting processes, mainly occurred since 1970, as a result of mean annual temperature increase and precipitation decrease compared to the historical average.
24 sie 2023 · Cirques are often the most representative and numerous landforms in alpine glaciated watersheds. The readily mappable and measurable nature of cirques (especially aspects and floor elevations) may yield information about the climatic, geologic, and topographic conditions that created them.
1 sty 2014 · Cirque glacier is a true hybrid concept referring both to the landform it creates through erosion and evacuation of rocks and sediments (Glacial Erosion: Glaciological Variables Controlling Glacial Erosion; Glacial Geomorphology and Landforms Evolution), and to the ice body occupying it in the first place. In certain areas of the world such as ...
21 maj 2022 · Three prominent results are noted: (i) cirques of the study area are larger than elsewhere, but most conspicuous is their relatively deep incision; (ii) there has been an above average rate of glacial downcutting; and (iii) optimal Pleistocene conditions for cirque formation were determined from analysis of cirque aspects.
