Differential Erosion Scans
Description:

Differential surface scans from parts of the external and internal walls of Nidaros Cathedral (Trondheim, Norway) and a pillar from the Elefsis archaeological site (Elefsis, Greece). The scans were taken in April 2013, September 2014 and November 2015. These can be used for the study of erosion under realistic conditions and can serve as a point of reference for the future.

Erosion Data from Slabs
Description:

Multimodal scans of marble and soapstone slabs across 2+ accelerated erosion cycles (number of cycles depends on erosion chamber). The slabs were subjected to accelerated erosion in erosion chambers simulating H2SO4 and H2SO4+HNO3 acid pollution, freeze-thaw and salt effects. The measuring modalities are high accuracy geometric surface scans, QEM mineral scans, computed tomography and 3D microscopy. These can be used for the study of erosion on stone.
