Determination of the density in a Svalbard ice core using digital photos
This study presents a simple and inexpensive method for deriving a high-resolution density proxy record for the firn part of an ice core using digital images. The image data have better resolution and are less sensitive to core quality than is density derived through dielectric profiling (DEP). Simp...
