Glacier Dynamics in a Changing Climate

Explore the variables affecting glacier flow including valley slope, ice temperature, and basal conditions. Learn how ice flows in different scenarios and settings, such as basal characteristics, PVC pipe experiments, valley slope angles, and ice temperatures. Discover the impact of warmer ice, basal conditions, and slope on glacier dynamics in a changing climate.

Presentation Transcript

  1. Glacier Dynamics in a Changing Climate ___________________________________________________________________________

  2. Variables that affect glacier flow: • Valley slope • Ice temperature • Basal conditions

  3. Glaciers Flow: • Downhill (slope affects flow speed) • Warmer ice flows faster • Ice is brittle (crevasses) & ductile • Basal characteristics are important (the presence of water at the bed)

  4. How Ice Flows: Basal Conditions Preparing the PVC pipe Basal Conditions PVC pipe lined with sandpaper Rough Bed Normal Bed PVC pipe PVC pipe lined with aluminum foil and lubricated with oil Lubricated Bed

  5. How Ice Flows: Valley Slope Angle of PVC pipe Valley Slope 25° Shallow 45° Medium 65° Steep

  6. How Ice Flows: Ice Temperature Flubber temperature warm ice normal ice cold ice Ice Temperature Cold Ice (blue flubber) Flubber placed in the freezer prior to class Normal Ice (white flubber) Flubber at room temperature Warm Ice (pink flubber) Flubber microwaved until hot to touch

  7. Lab setup basic setup advanced setup
