SITE DESCRIPTION
Active layer
monitoring at the Chara Most CALM grid was initiated
in 2013. Studied area is located in the east from Chara downtown, north of the Chita region, East Siberia. CALM site is situated on the fluvial plain with elevation ranging from 705 to
SOIL DESCRIPTION: (predominant texture, i.e.,
‘sand’, ‘gravel’, ‘peat’, etc.): Geological section is composed by sandy silt
and peat overlaid by sands with gravel. In previous year moisture (water mass
to mass of dry soil) and density of these soils were studied in laboratory.
The water content of peat varies from 250 to 300 % and density varies from 0.7
to 1.3 g/cm3. The moisture of sandy silt ranges from 35 to 60%.
SAMPLING DESIGN AND METHOD:
1-ha grid consists of a square array of permanent
stakes separated by
