WEATHER CONDITIONS

Season phenology: late

Weather conditions:

Spring was late. This probably caused the absence of Brent Geese Branta bernida broods and the large proportion of non-breeding pairs in Glaucous Gulls. Air temperature after 10 June was similar to long-term averages. Between 1-10 August it snowed, with snow cover remaining for two days.

BIOTIC CONDITIONS

Rodents abundance evaluation:

low

Breeding conditions:

The number of Arctic Foxes at Bolshevik island was low. Breeding of Purple Sandpipers at Bolshevik island was considered successful although hatching took place during a shorter period than in 1991. On this island a few breeding Sanderlings Calidris alba were recorded as well.
 

Rodent dynamics:

Lemming numbers at the Bolshevik island were as low as in 1991: lemmings were not seen at all, although winter nests and several inhabited holes were found. At the Cheluskin peninsula lemming abundance was evidently greater, as several very local areas were found which were regularly visited by Arctic Foxes.
