GRIP Basal Ice: Crystal Sizes
Depth is midpoint. Crystal refers to the average horizontal crystal diameter in mm. -
GRIP Ice Fabric
36 fabric diagrams. Each data point consists of azimuth of c-axis (0-360 deg), and inclination (0-90 deg), with 0 deg=horizontal c-axis and 90 deg=vertical c-axis. The measured... -
