SAMPLING DESIGN AND METHOD:
1-ha grid consists of a square array
of surveyed permanent stakes separated by 10 m, yielding an 11 × 11 array
of sampling nodes on each grid. Thaw depth and snow sampling was conducted
twice by manual probing at each stake. The two values for each sampling point
are averaged, yielding a maximum of 121 data points per grid per probing date.
The active layer was not measured at locations where grid points intersect
rocks or deep water.
