Kamb Ice Stream (Dating Kamb Shutdown (Radargram Findings: (Continuous…

- - - - Ice accumulating from snowfall
      - Interannual layers
    - - ∴ Disturbed layers evince ice stream
      - Ice streams deform/crevasse radar layers
- - - - Velocity = v. sensitive to ice stream width
      - Basal heat generated = f(basal stress & velocity)
    - - 1. Reduced velocities - as lateral stresses become more dominant
      - 2. Reduced basal meltwater ∴ less basal sliding
      - ∴ Negative heat balance at bed so bed freezes
  - - - Steeper region transmits driving stress non-locally into Whillans Ice Plain
      - Influences basal stress there
