Lin Liu pulls a ground penetrating radar unit through the tundra in rainy weather as Andy Persekian and Elchin Jafarov follow behind. 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.
