The results of 16 years of seasonal thaw depth observations in permafrost landscapes near Yakutsk have been presented. For the first time in Central Yakutia, the observations at two sites have been carried out following the CALM program protocol on a dense grid of frost/thaw tubes. Measurements have provided new data on the effects of landscape conditions, winter season and rainfall on interannual variations in seasonal thaw depth.
