 note = {This study investigated palsa located at the southern margin of palsa extent upon the Kola Peninsula, Russia. Thirteen palsa bogs were analyzed, two of which had intervals between surveys of either 67 years (1935?2002) or 82 years (1920?2002). The thickness of the active layer of palsa during the warm season varied from 44 to 64 cm, consistent with existing data. The height and number of bog mounds, as well as the thickness of the active layer, are unchanged over the past 80 years., この論文ではコラ半島南部ロシア側に分布するパルサ（レンズ状に成長する凍土領域）を扱う。パルサを有する13の湿地を調査したが、そのうち4つは67年あるいは82年の間隔をおいている。パルサの活動層の厚みは温暖期において44-64?であり、従来の出版報告と一致する。湿地の数、高度、パルサの活動層の厚みはこの80年間、変わっていない。},
