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.

 

 

SOIL DESCRIPTION: (predominant texture, i.e., ‘sand’, ‘gravel’, ‘peat’, etc.):

 

Typic Molliturbel

 

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.
