Table comment: Abundance based on using aerial counts of dens on the Severnaya Zemlya in 1982 and on anecdotal data collected in 1960-80s on the number of females coming to dens on Novosibirsk Islands and on mainland coast. The estimate should be regarded as dated and preliminary.
The Laptev Sea subpopulation (LP) area includes the western half of the East Siberian Sea and most of the Laptev Sea, including the Novosibirsk and possibly Severnaya Zemlya islands (Belikov et al. 1998). The 1993 estimate of subpopulation size for LP (800 – 1,200) is based on aerial counts of dens on the Severnaya Zemlya in 1982 (Belikov and Randla 1987) and on anecdotal data collected in 1960–80s on the number of females coming to dens on Novosibirsk Islands and on the mainland coast (Kischinski 1969, Upenski 1989).
