High-density crust record from firn cores B40 and B54, East Antarctica

From snow profiles measured by means of microfocus X-ray computer tomography we created a unique dataset showing the spatial distribution of crusts in snow on the East Antarctic Plateau as well as in northern Greenland including a measure for their local variability.

With this method, we are able to find also weak and oblique crusts, to count their frequency of occurrence and to measure the high-resolution density.
