Bemerkungen/Beschreibung

This study aims to test the reliability of the Schmidt hammer for measuring glacial recession at the Schlatenkees in the Austrian Alps. Most Schmidt hammer studies use relative dating on landforms, however in this study, sites can be absolutely dated through historical and aerial imagery. As there is little literature on the application of the Schmidt hammer on recently deglaciated gneissic terrain, this study helps to fill in this literature gap by testing the Schmidt hammers reliability on twenty-six sites across the Schlatenkees foreland.
Geomorphological mapping was undertaken and identified several features that related to glacial retreat in the Schlatenkees foreland. The results from the Schmidt hammer were variable, none of the four transects showed a statistically significant relationship between r-value and distance from the ice. Although, the r-value closest to the ice was higher than the site furthest away on all transects. This highlighted that there was some general reliability in the Schmidt hammer, despite the variation along the transects. A statistically significant relationship was observed between the transect r-value and elevation which showed its reliability as aerial imagery documented its retreat from higher to lower elevation. The Schmidt hammer did prove unreliable in some cases however, one site highlighted the effect of lithology on the Schmidt hammer and suggested that lichen may also have an influence on the r-value. Highlighting that gneiss may not be suitable for Schmidt hammer application and the affect lichen cover has on rock surfaces requires further work.
