Collaborative Research: Using Fracture Patterns and Ice Thickness to Study the History and Dynamics of Grounding Line Migration and Shutdown of Kamb and Whillans Ice Streams
Entry ID: fahnestock_0440636_1

Abstract: The work is in collaboration with co-PI Christina Hulbe and at Portland State University. In our previous work we were able to image, map, and interpret streak lines (flow trajectories) on the Ross Ice Shelf and demonstrate, using numerical simulations, that this pattern of flow-related features required significant changes in flow direction in the outflows of a number of ice streams on the Siple ...
