Hawley and Morris (2006) demonstrated a link between firn density and optical properties using borehole optical stratigraphy (BOS), and many ice-core We measured and weighed the 35 core sections in the field to obtain gravimetric densities. (a) NP (grey) and DEP (black) density profiles; (b) COS profile, a mean brightness from the core imagery; and (c) digital imagery of firn and ice using NP, DEP, COS and gravimetric density method for measuring snow and ice density.	./cache/work_obyjx4brwvcdfmdsgdpgajvkoq.pdf	./txt/work_obyjx4brwvcdfmdsgdpgajvkoq.txt
