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

View Catalog Page

Entry ID

NSIDC-0515

Summary

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
