Borehole Optical Stratigraphy measurements through 4 full years at Summit, Greenland

These data consist of detailed measurements of the temporal and spatial variations of firn compaction to advance knowledge and understanding of ice deformation and across different fields, including remote sensing, snow morphology, and paleoclimatology. These details can be tracked over time to determine vertical motion and strain, which in the shallow depth is dominated by firn compaction. These data were gathered using the concept of Borehole Optical Stratigraphy (BOS). Borehole Optical Stratigraphy is a method for recording the visual stratigraphy in a snow/firn borehole, generating a profile of brightness versus depth. The BOS instrument is a downward-looking video camera that is lowered down a borehole. The lens is wide-angle, and the view includes the walls of the borehole. These data cover accumulation rates occurring between 1980-2008, and the data were collected between 2004-2009.
