Ice Fabric Characteristics: Siple Dome, A Core
Entry ID: NSIDC-0255

Abstract: This data set contains measurements of the orientation and deformation of the crystal c-axes (fabric) of ice core samples collected from the Siple Dome Ice Core A, Antarctica (81�S, 148�W) between 22.764 m and 992.385 m in depth. The instrument used for the measurements consists of a fiber-optic white light source, one fixed black-and-white video camera, and four rotation stages. The data are in ASCII tab-delimited text format and are available via FTP.

Quality Many of the vertical sections were not mounted vertically in the instrument for various technical reasons; therefore, the pattern of c-axes is actually rotated from the vertical. The mount orientation of the samples is given in a separate file titled 'sample orientation.doc.' This file contains a list of all the samples specified by depth, followed by the tipping angle.
