WAIS Divide Laser Dust Logger Data
Entry ID: bay_0738658

[ Get Data ]

Abstract: Preliminary data from an optical log made at WAIS Divide with the laser dust logger in December 2011, in the clear ice at depths between 1403.58 m and 3329.8 m. The Dust Logger measures the amount of light beamed into the horizon which exits the borehole and returns. Depths have been corrected to match the core, to an accuracy of <5 cm typical and ~20 cm maximum, using tie points known from visual core assays.
