Introduction
The study of the Earth’s glaciers and ice sheets is of tremendous importance as their fluctuation has consequences on sea level, river flow, ecosystem functioning, ocean circulation, and climate stability. Recent studies have shown that the Earth’s small glaciers are in measurable decline on account of secular atmospheric warming (Kaser et al., 2006; UNEP/WGMS, 2009), and whose environmental services (e.g., hydrological regulation) vary regionally – from short-term flow augmentation to long-term decline (Bonardi, 2008; Casassa et al., 2008; Sauchyn et al., 2008). There is considerable concern regarding the...
