Annual Layers at Siple Dome, Antarctica, from Borehole Optical Stratigraphy, Version 1

Researchers gathered data on annual snow layers at Siple Dome, Antarctica, using borehole optical stratigraphy. This data set contains annual layer depths and firn optical brightness. The brightness log is a record of reflectivity of the firn, and peaks in brightness are interpreted to be fine-grained high-density winter snow, as part of the wind slab depth-hoar couplet.

Data are available via FTP in ASCII text (.txt) format
