| Summary: | We provide a review of records of Walrus Odobenus rosmarus near the coast of the Yamal-Nenets autonomous district in the last twenty years: 2000-2019. Single animals and small groups (10 and fewer individuals) have been observed in the adjacent waters of the Kara Sea from icebreakers and ships sailing the Northern Sea Route. On the western coast of the Yamal Peninsula, walruses have been recorded in historically known haulout places on the Sharapovy Koshki Islands. The remains of an adult walrus were found in the Sharapov Shar Bay at the mouth of River Naduyakha in early August 2013, and 30 individuals were observed on coastal haulout on Cape Kharasavey of the northern Sharapovy Koshki Island on 23 August 2019. A haulout of 300 animals was recorded at the mouth of River Tivteyakha in the northwest of Yamal from the end of September until 20 October 2019. More animals could be seen in the water near the coast, which makes it possible to estimate the total number of animals at about 600-1000 individuals. On Bely Island, “quite a lot” of walruses are regularly recorded both on and off the coast. Single individuals (no coastal haulouts) were seen in the north of Yamal, in the Gulf of Ob and on the Gydan Peninsula. Two walruses were observed in the Malygin Strait on 24 October 2010. In the Gulf of Ob, walruses were observed in Sabetta settlement (two walruses at different times in March 2018), in Seyakha village (a single walrus at the end of December 2005), near Cape Kamenniy (a young female about 2 years old in early December 2010). Thus, walruses have been recorded down south to N68º27’. In the north of the Gydan Peninsula, individual animals have been seen in the sea near Vilkitskiy Island and in the Gydan Bay, where in mid-October 2018 a young walrus appeared in Gyda village. The regular current sightings of walruses near the coast of Yamal as compared with the data from the previous half-century period confirm the assumption about an increase in the Atlantic Walrus population in the southern Kara Sea. Sightings of walruses in March and December may indicate that some walruses stay in the Kara Sea over winter and do not go to the traditional wintering sites in the southeast of the Barents Sea and off the coast of Novaya Zemlya. |
