Compilation of high-density crusts in snow from various locations in Dronning Maud Land (East Antarctica) and northern Greenland

Thin crusts in snow with high density contribute to firn stratigraphy and can have significant impact on firn ventilation as well as on remotely inferred properties like accumulation rate or surface mass balance. From snow profiles measured by means of microfocus X-ray computer tomography we created...

Description
Summary:Thin crusts in snow with high density contribute to firn stratigraphy and can have significant impact on firn ventilation as well as on remotely inferred properties like accumulation rate or surface mass balance. 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.
