2. CONTINENTAL ICE SHEET - GREENLAND

3. ALPINE ICE- VALLEY GLACIER(S)

4. GLACIER BAY, ALASKA

5. ALL GLACIERS HAVE TWO ZONES ACCUMULATION = + MASS ABLATION = - MASS

6. “Firn Line” = Equilibrium Line Italian alps Dinwoody Glacier. Wind River Range, Wyoming.

7. GAME OF MASS BALANCE SNOW IN vs WATER/ICE OUT

8. IDEALIZED MOTION- CROSS SECTION

9.  = strain rate A = constant related to ice temperature  = basal shear stress (?) n = exponent with an average value of 3 GLEN’S FLOW LAW  gh sin 

10. TEMPERATURE MATTERS Does cold or warm ice strain more rapidly?

11. STRESS-STRAIN RESPONSE (WATER) (DEBRIS FLOW)

12. MASS FLUX - BIRD’S EYE VIEW

13. VELOCITY DISTRIBUTION - BIRD’S EYE

14. VELOCITY IN SECTION VIEW WHAT’S GOING ON AT THE BED????

16. WHAT IS THE TEMPERATU RE AT THE BASE OF THE ICE? - GEOTHERMA L -FRICTION -AMBIENT AIR

17. WARM BASED ICE sliding along bed

18. FOX GLACIER, New Zealand

19. COLD-BASED ICE frozen to bed

20. DRY VALLEY AREA-- ANTARTICA

21. COMPARE, WARM VS COLD

22. U IMPLICATIONS FOR EROSION INTENSITY CLASSIC U- SHAPED VALLEY EROSION REQUIRES WARM BASED ICE, WHY?

23. PLUCKING ….

25. PLUCKING IN ACTION
