WEATHER CONDITIONS

Season phenology: average

Weather conditions:

Weather was favourable for wader breeding. Adjacent to sea tundra 2-2.5 km wide became snowfree in late May. Minimal air temperature crossed 0^C on 11 June. Mean minimal and maximal temperatures in June equalled +0.4^C and +6.8^C, respectively, in July - +1.3^C and +9.4^C, in August - -1.1^C and +3.8^C. The last weak snow fell on 13 June, the first one - on 2 August. During fledging of Thick-billed Murre young the seashore was blocked with ice (almost 100%) which caused mass death of fledglings.

 

Season temperature:
Season humidity:
Date of 50% snow-cover: late May-early June
Date of ice-break on rivers: early June
Date of final loss of snow: mid June

BIOTIC CONDITIONS

Rodents abundance evaluation:

average

Breeding conditions:

Arctic Foxes were scarce, their breeding was not proved. Among skuas, Long-tailed and Arctic were breeding in small numbers. Snowy Owls successfully bred, and were common in inland areas. All typical for the island wader species were breeding: Grey Plover, Turnstone, Knot, Baird's and Pectoral Sandpipers, and, probably, Ringed Plover. Chicks hatched in all the controlled nests (which were few). Well flying Knot and Baird's Sandpiper young were seen in the end of July.
 

Rodent dynamics:

Lemmings (mainly Collared) had average density: single records were made daily.

Rodent species recorded:
