Ice streams are dynamical features that control the ice flow from an ice sheet's interior to its margin. Due to their dynamical nature, ice streams may change flow speed and direction in response to external forcing or due to internal variability. This study investigates the interplay between neighbouring ice streams that feed the Dotson and Crosson Ice Shelves in West Antarctica. The authors use satellite observations to measure the change in ice speed and flow direction from 2005 to 2022, and their observations reveal a highly complex pattern of dynamical changes and the redirection of ice flow from one stream to another. These observations reveal previously undocumented impacts of spatially varying ice flow, which may influence the ice shelf and ice sheet.
