Klappentext The book deals with push moraines on Spitsbergen. The main body is a translation of the original German report by Karl Gripp on a 1927 expedition. The quality of Gripp's work is evaluated to see whether it stands the test of time. It is found that it is very modern! every year people still go into the field with the same research questions. It is also found that most likely Gripp's report contains the first description of features that we now take for granted! for instance the description of looped moraines to detect surges. Push moraines are still being studied and to show where we stand now two papers have been added that analyse two particular examples! Holmstrmbreen and Sefstrmbreen. The two examples are geographically close together! but reflect two completely different settings: terrestrial Holmstrmbreen and tidewater Sefstrmbreen. Since a few years we know of the De Geer Archive! a collection of glass negatives of Spitsbergen! relating to De Geer's expeditions between 1882 and 1910. The negatives have only emerged recently and a collection of prints relating to Holmstrmbreen and Sefstrmbreen is included here. Together with a third paper incorporated in the book! this time an evaluation of De Geer's photos and maps of the Sefstrmbreen surge! this material shows the importance of incorporating historical documentation in our studies. Zusammenfassung Deals with push moraines on Spitsbergen. Push moraines are ridges or mounds of stratified glacial drift that are generated by glacial movement. Spitsbergen is an island in the Norwegian Sea! approximately 350 miles north of mainland Norway near the Norht Pole. Inhaltsverzeichnis 1. Introduction. 2.
