Soil Data from Picea mariana Stands near Delta Junction, Alaska of Different Ages and Soil Drainage Type

The U.S. Geological Survey project Fate of Carbon in Alaskan Landscapes (FOCAL)
is studying the effect of fire and soil drainage on soil carbon storage in the
boreal forest. This project has selected several sites to study within central
Alaska of varying ages (time since fire) and soil drainage types. This report
describes the location of these sampling sites, as well as the procedures used
to describe, sample, and analyze the soils. This report also contains data
tables with this information, including, but not limited to field descriptions,
bulk density, particle size distribution, moisture content, carbon (C)
concentration, nitrogen (N) concentration, isotopic data for C, and major,
minor and trace elemental concentration.
