Map-based methods for estimating glacier equilibrium-line altitudes
We examine the validity of two methods for estimating glacier equilibrium-line altitudes (ELAs) from topographic maps. The ELA determined by contour inflection (the kinematic ELA) and the mean elevation of the glacier correlate extremely well with the ELA determined from mass-balance data (observed ELA). However, the range in glacier elevations above sea level is much larger than the variation ...
متن کاملEquilibrium-Line Altitudes of Late Quaternary Glaciers in the Zardkuh Mountain, Iran
Equilibrium-line altitudes (ELAs) of former glaciers in the Zardkuh Mountain of the Zagros Mountain Range were reconstructed from glacial-geologic data on former ice limits by using various methods. In the study area various types of glacial landforms such as outwash fans, moraines and well developed glacial cirques are observed. The results suggest that ELA were depressed 1433 m below to prese...
متن کاملAutomating the implementation of an equilibrium profile model for glacier reconstruction and Equilibrium Line Altitude calculation in a GIS environment
Reconstruction of glacier equilibrium line altitudes (ELAs) associated with advance stages of former ice masses is widely used as a tool for palaeoclimatic studies. This requires an accurate reconstruction of palaeo-glacier surface hypsometry, based on geomorphological evidence. Classically, the approach used to define ice-surface elevations follows the ‘cartographic method’, whereby contours a...
