| Definitionskos:definition | Elongate landforms, produced typically in subglacial sediments, which reflect fast ice flow of an ice sheet and thought to be indicative of ice streaming. MSGLs characteristically have length:width ratios greater than 15:1 and have a convergent flow pattern. MSGLs typically have a large zone of convergence feeding into a main trunk, which may then diverge again near the ice margin (Excerpt from Bell et al. 2016, adapted from Bell et al. 1997. In: Dowdeswell et al., 2016). |
