| Summary: | Soil profiles at 27 sites in northern Alaska were described and classified in order to provide baseline soils data for ARCSS/LAII/ATLAS (Arctic Transitions in the Land-Atmosphere System) Winter Carbon Flux studies. The investigators collected samples and field data in the summers of 1992, 1998, 1999, and 2000. Profile descriptions include horizon depth, color, texture, and other morphological properties. Accompanying sample site descriptions provide information about landforms, vegetation cover, and soil parent material. Soils are classified according to USDA soil taxonomy guidelines. Laboratory analyses include measurements of soil water content, bulk density, texture, organic matter content, carbon storage, pH, and chemical components including carbon, nitrogen, calcium, phosphorus, potassium, aluminum, manganese, and iron. Profile descriptions, laboratory data, and soil pit photographs and profile sketches are available in MS Excel, MS Word, and .JPG formats.
