| Abstract | A detailed textural analysis was conducted on a core collected on an ice island which originated from the Ward Hunt ice shelf. Crystal size and morphology were determined at nine sites along the length of this core, with the use of a statistics software designed to produce this data from digitised images of thin sections. The orientation of the [00011 axis of the grain assemblages was also determined. These variables displayed little variation with depth, suggesting a common origin of the ice throughout its thickness. A vertical single-maxima in lattice orientation is reported. This feature may be accounted for in two ways: 1) The present Ward Hunt ice shelf represents the base of a previously thicker ice sheet; 2) the observed lattice orientation was initiated early in the history of deposition leading to the formation of the shelf ice. |
