SITE DESCRIPTION
This site is located on the Bely
island on an edge part I marine terrace. Its altitude ranges from 3 to 7
meters. The embedded 25 × 25 m CALM site lies in the 2.8-3.7 m altitude
range. The upper part of the lithological section on the site is composed of
sands. The surface is covered with
spotted-fractured forb-dwarf willow (Salix polare)-racomitrium-gymnomitrion tundra with a small-polygonal nano-relief, outlined by a moss Racomytrium
lanuginosum. The surface of the knobs is cracked,
covered with a crust of hepatic moss Gymnomitrion corallioides and lichens (crustose lichen is prevail). The total thickness of the organic cover (moss,
lichen, peat) is 3-5 cm in interpoligon cracks.

SAMPLING
DESIGN AND METHOD:
25x25
m grid consists of a square array of surveyed permanent stakes separated by 5
m, yielding a 6 × 6 array of sampling nodes on each grid. Thaw depth was
conducted thrice by manual probing at each stake. The three values for each
sampling point are averaged, yielding a maximum of 36 data points per grid per
probing date.
