Cold windy weather with temperatures not exceeding +14.5øC and dropping below freezing at night, and strong northeasterly or northwesterly winds prevailed during the first 3 days. The following warming resulted in increase of the day-time temperature to +20øC and intensive melt of snow. Fog was common in the morning, while pelting rain and thunderstorm occurred at night.

Breeding conditions:
|
Rough-legged Buzzards bred successfully: 2 chicks were observed on 7 July in the nest found with a clutch of 5 eggs on 2 July, a nest with 4 eggs was found on 3 July, and another one with 4 chicks on 5 July. Other birds of prey were not observed. Long-tailed Skuas were numerous across the study area and attacked observer, but nests were not found. Single birds and pairs of Pomarine Skuas were recorded, but territorial behaviour was not observed in this species. Breeding record of Larus heuglini was made.
White-fronted Goose, Red-breasted Goose and Long-tailed Duck bred in the area. Among waders Greater Golden Plover, Red-necked Phalarope, Ruff, Little Stint, Temminck's Stint and Dunlin belonged to confirmed breeders. Passerines were numerous, including breeding Shorelark, Red-throated Pipit, Yellow-headed Wagtail, Willow Warbler , Chiffchaff, Common Redpoll, Little Bunting, Bluethroat, Redwing and Lapland Bunting.

Rodent dynamics:
|
| Small mammal surveys were not conducted. Rodent abundance was average, as lemmings were rarely seen, but were often captured by dog. Siberian Lemming prevailed both in dog catch and in prey of Rough-legged Buzzards, while Collared Lemming was less abundant (single captured by dog).
