KS_1259.jpg
116 viewsLin 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.

permafrost, nsidc, kevin schaefer, alaska, barrow112 viewsAndy Parsekian, Kevin Schaefer, and Lin Liu use a ground penetrating radar to measure the depth of an ice wedge on August 15, 2013. The survey line lies perpendicular to the ice wedge and similar ice wedges crisscross the tundra in the background (Credit: Elchin Jafarov, NSIDC).
