Lin Liu pulls a ground penetrating radar unit through the tundra in rainy weather. The survey near Barrow, Alaska measures active layer depth. The radar unit (in the box) emits a pulse which reflects off the permafrost to measure the active layer depth, which is recorded in the computer held by Andy Parsekian.
