21 lis 2017 · We used ArcGIS to measure length, width, aspect, latitude and distance to coastline of each cirque. Palaeo-equilibrium-line altitudes (palaeo-ELAs) of palaeo-cirque glaciers were calculated using the altitude-ratio method, cirque-floor method and minimum-point method.
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.
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.
15 sty 2024 · In this study, we analyse the morphometry of cirques in the Transantarctic Mountains (TAM) to understand regional glacier formation and landscape evolution since the onset of Cenozoic glaciations.
This study uses geomorphological mapping of landforms at and adjacent to Wolf Crags, the site of a previously reconstructed cirque glacier, at the northern end of the Helvellyn range, eastern...
1 lut 2022 · This paper introduces an automated method to recognize and delineate cirques using DEMs based on a series of hydrological and morphological analyses, including delineating stream network, filtering streams, determining potential cirque threshold points, and delineating cirque outlines.
The cirque glacier has an area of 0.5 km 2 and a surface inclination of about 16°. The general ice flow is directed towards the north. Near the centre of the glacier, the surface ice velocity has been measured at about 2 m a −1. At present, Passglaciären fills its cirque almost entirely, suggesting future expansion would start to infill the ...
