| Zusammenfassung |
Samoylov Island is centrally located within the Lena River Delta at
72° N, 126° E and lies within the Siberian zone of
continuous permafrost. The landscape on Samoylov Island consists mainly of
late Holocene river terraces with polygonal tundra, ponds and lakes, and an
active floodplain. The island has been the focus of numerous
multidisciplinary studies since 1993, which have focused on climate, land
cover, ecology, hydrology, permafrost and limnology. This paper aims to
provide a framework for future studies by describing the characteristics of
the island's meteorological parameters (temperature, radiation and snow
cover), soil temperature, and soil moisture. The land surface characteristics
have been described using high resolution aerial images in combination with
data from ground-based observations. Of note is that deeper permafrost
temperatures have increased between 0.3 to 1.3 °C over the last five
years. However, no clear warming of air and active layer temperatures is
detected since 1998, though winter air temperatures during recent years have
not been as cold as in earlier years.
