Spitsbergen Push Moraines
Including a translation of K. Gripp: Glaciologische und geologische Ergebnisse der Hamburgischen Spitzbergen-Expedition 1927
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, HolmstrÃ¶mbreen and SefstrÃ¶mbreen. The two examples are geographically close together, but reflect two completely different settings: terrestrial HolmstrÃ¶mbreen and tidewater SefstrÃ¶mbreen.
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 HolmstrÃ¶mbreen and SefstrÃ¶mbreen 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 SefstrÃ¶mbreen surge, this material shows the importance of incorporating historical documentation in our studies.
