  Glaciology became my principal focus in the s, as I sought to understand the genesis of glacial landforms. I spent 15 years working on Barnes Ice Cap, Baffin Island, focusing on the mechanics of moraine formation at the margins of polar ice sheets and on the temperature distribution and mechanics of deformation in such ice sheets.

Superimposed ice at the margin of the Barnes Ice Cap, Baffin Island, Canada, has been overridden and deformed by the main glacier. Deformation within the overridden ice is of variable intensity, and is characterized by zones of shear which are a few centimeters thick and which lie almost parallel to the bed rock and to the measured direction of Cited by: Some recent work by Dr. J. F. Nye on the calculation of the thickness of ice sheets has prompted the author to apply Nye’s formula to the Barnes Ice Cap in Baffin Island. A gravimetric survey of the southern lobe was carried out in , and the data from four of the traverses have been used to calculate the variation of the shear stress on.   The awesome beauty and majesty of glaciers, the world of ice which has shaped and reshaped large parts of the earth's surfaces, are presented here through more than one hundred photographs and a closely integrated, informed text.

Abstract. The steady state tertiary creep of ice which is attained at total strains in excess of ~ 20% is examined. By the term “creep” we imply that we shall examine ice deforming at 20% take long times to establish in the laboratory. At these large strains, crystal anisotropy plays a most important role in the Cited by: 3.

The pollen spectra are dominated by long distance transported pollen, especially the conifers Picea and Pinus.
