River incision, in response to glacial rebound, could explain why typical coarser fluvial top‐sets are absent at the sites L1 and L2 (Fig.…”

“…Vtyurin (1989) reported that 'ice cement' dominated in seasonally and perennially frozen ground and permafrost with segregation ice is widespread in central and western Svalbard. Ice-rich permafrost in the area occurs in ice wedges (Matsuoka & Hirakawa 1993;Meier 1993), pingos (Ross et al 2005(Ross et al , 2007, rock glaciers (Isaksen et al 2000b;Humlum et al 2007), talus fans (Siewert et al 2012), and slope and terrace deposits (Liestøl 1962;Bibus et al 1976;Meier & Thannheiser 2009).

This paper presents the history and cryostratigraphy of the upper permafrost in the High‐Arctic Adventdalen Valley, central Svalbard. Nineteen frozen sediment cores, up to 10.7 m long, obtained at five periglacial landforms, were analysed for cryostructures, ice, carbon and solute contents, and grain‐size distribution, and were 14C‐ and OSL‐dated. Spatial variability in ice and carbon contents is closely related to the sedimentary history and mode of permafrost aggradation. In the valley bottom, saline epigenetic permafrost with pore ice down to depths of 10.7 m depth formed in deltaic sediments since the mid‐Holocene; cryopegs were encountered below 6 m. In the top 1 to 5 m, syngenetic and quasi‐syngenetic permafrost with microlenticular, lenticular, suspended and organic‐matrix cryostructures developed due to loess and alluvial sedimentation since the colder late Holocene, which resulted in the burial of organic material. At the transition between deltaic sediments and loess, massive ice bodies occurred. A pingo developed where the deltaic sediments reached the surface. On hillslopes, suspended cryostructure on solifluction sheets indicates quasi‐syngenetic permafrost aggradation; lobes, in contrast, were ice‐poor. Suspended cryostructure in eluvial deposits reflects epigenetic or quasi‐syngenetic permafrost formation on a weathered bedrock plateau. Landform‐scale spatial variations in ground ice and carbon relate to variations in slope, sedimentation rate, moisture conditions and stratigraphy. Although the study reveals close links between Holocene landscape evolution and permafrost history, our results emphasize a large uncertainty in using terrain surface indicators to infer ground‐ice contents and upscale from core to landform scale in mountainous permafrost landscapes.

Julius Büdel and Climatic Geomorpholgy The geomorphological models of peneplain and valley formation of the prominent and influential German geographer Julius Büdel (1903-1983) are taken by a critical analysis. It demonstrates that the "double planation" in the humid tropics substantiated by weathering and soil formation processes and therefore by actual climate factors and the in the same way substantiated "ice rind effect" in the subpolar regions are not acceptable-neither pedologically nor geomorphologically. That means: these processes do not exist. They cannot explain the peneplain and valley relief outside of the recent tropics and polar regions, respectively, which was a major intent of Büdel. Weathering and soil formation do not act as "pacemaker" or as "motor" as Büdel 1) Stark erweiterte und zum Teil veränderte Fassung des gleichnamigen Vortrags auf dem 1.
