Images of ice core sections that have been processed at the U.S. National Ice Core Laboratory - McGwire_0230149

The dataset is comprised of optical images of ice core sections that were acquired with a digital line-scan camera in the cold room facility at the U.S. National Ice Core Laboratory (NICL). Ice core sections are archival cuts which have are rough-out rounds of ice with a single plane cut along one side. Illumation is provided to the sides of the ice section using fiberoptic light guides connected to a 1000W xenon light source. Original image resolution varies, generally in the range of 0.05 to 0.1 mm.
