Polar Desert Soils¹

ABSTRACT

The northern extremeties of ice-free land are mantled primarily with Polar Desert soils. Polar Desert soils are sparsely colonized by vascular plants and in many instances the organic component scarcely enters the soil system. Low temperature, relatively dry soil conditions, a desert pavement, mildly acid to alkaline reaction, and salt efflorescences commonly characterize the Polar Desert soils.

¹ Journal series paper of the Agricultural Experiment Station, Rutgers. The State University of New Jersey. These studies were aided by a contract between O.N.R., Department of the Navy, and the Arctic Institute of North America. The (Canadian) Polar Continental Shelf Project furnished logistical support for these studies. Appreciation is expressed to G.F. Walton (Rutgers) for field assistance, to R.F. Faylor (A.I.N.A.) and E.F. Roots and F.P. Hunt (P.C.S.P.) for project coordination and administration. Valuable information concerning soils and geology of Prince Patrick Island was furnished by J.G. Fyles of the Canada Geologic Survey. Appreciation is also expressed to pilots J. Jamieson and D. Walin. Laboratory analyses were made by C. Hornig.
