Properties and Classification of Cold Desert Soils from Antarctica
Abstract Eight pedons representing three climatic zones and parent materials ranging from Holocene to Pliocene were characterized from the Dry Valleys region of Antarctica. All of the soils contain abundant water‐soluble salts, including NaCl in coastal regions, NaNO 3 along the polar plateau, and N...
