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.
