Mapping the ice stratigraphy in IceCube using camera deployment footage

The IceCube Neutrino Observatory is a cubic-kilometer Cherenkov array deployed in the deep,
glacial ice at the geographic South Pole. An important feature of the instrumented ice are
undulations of layers of constant optical properties over the footprint of the detector. During
detector construction, these layers were mapped using stratigraphy measurements obtained from
a stand-alone laser dust logger. While this system is very precise, its cost does not scale to the
instrumented volume envisioned for the proposed IceCube-Gen2 Observatory. Here, we explore
the possibility of obtaining equivalent stratigraphy data from camera footage recorded during
the deployment of IceCube more than a decade ago. If successful, this could be an alternative
technique to be considered for IceCube-Gen2.
