Photo showing data acquisition of a typical scan position. The Riegl VZ1000 terrestrial laser scanner is inside the custom heater case (metal cylinder) on top of the tripod. The researcher controls the scanner from the laptop via WiFi. To the right of the tripod is a Riegl 10 cm cylinder reflector mounted on a post frozen into the ice. The Polarstern can be seen in the background along with other installations of the ice camp including Balloon Town3 (orange tents) and Ocean City4 (blue and white tent). Photo credit: S.
