WebApr 26, 2024 · A key constraint on the flow of ice sheets is crystal orientation fabric (COF), the distribution of crystal orientations within the ice (e.g. Alley, 1988; Azuma, 1994; Mangeney and others, 1997 ). Because ice crystals are elastically anisotropic, the speed of an elastic wave traveling through ice is affected by COF. WebDue to this, the aggregate orientations of crystals (the crystal fabric) has a large e ect on bulk ice ow in ice sheets. If the orientations are anisotropic, the ice has a bulk anisotropic response to stress. Conversely, ice ow drives development of crystal orientation fabric …
