Soil-Landscape Relations at Selected Sites Along Environmental Gradients in Northern Alaska.
This report was prepared from data gathered between 1976 and 1980. The objectives are: (1) To trace the development of soils, especially those of the wet tundra, and their relationship to associated microtopography; (2) To determine to what extent the wet tundra soils and their related microtopograp...

| Summary: | This report was prepared from data gathered between 1976 and 1980. The objectives are: (1) To trace the development of soils, especially those of the wet tundra, and their relationship to associated microtopography; (2) To determine to what extent the wet tundra soils and their related microtopography are the products of a cyclic repetition of events involving vegetation succession and hydrologic changes (tussock tundra) or, in the case of the very wet polygonized tundras, are the products of an evolutionary sequence leading to the abolition of the pattern and the creation of a new landform-soil association; (3) To determine the time frame in which these processes occur and thus gain an understanding of the temporal stability of the soils and landforms along the regional gradients and within selected mesogradients; and (4) To produce a detailed series of soil-landform maps and soil characterizations for selected areas along the gradients using the techniques developed for the coastal plain tundra. Original contains color plates: All DTIC and NTIS reproductions will be in black and white. |
