WebJun 22, 2024 · Ice streams are corridors of fast flow within an ice sheet (ca. 800 metres per year). They discharge most of the ice and sediment from these ice sheets, flowing orders of magnitude faster than their surrounding ice. ... Switch of flow direction in an Antarctic ice stream. Nature, 419: 465-467. 19. Horgan, H.J. and S. Anandakrishnan, … WebFlowlines on ice sheets and glaciers form complex patterns. To explore their role in ice routing and extend the language for studying such patterns, we develop a theory of flow convergence and curvature in plan view. These geometric quantities respectively equal the negative divergence of the vector field of ice-flow direction and the curl of this field. …
