Opis

Lowland glaciers are usually considered the best analogs for formerly glaciated areas and as such, many Icelandic glaciers have been intensively investigated with regard to process-orientated sediment-landform interrelationships. The Myrdalsjokull ice cap has, thus, served as an excellent "ice-age laboratory." Furthermore, a substantial effort has been directed toward understanding the interaction between volcanic activity and glacier response, such as meltwater outbursts (jokulhlaups) and sudden events of rapidly flowing glacier ice. The book reviews the following themes related to Myrdalsjokull: glaciology, glacial and quaternary geology, sedimentology, tephrochronology and eruption history of Katla, and crustal movements. All authors are involved in research about the subglacial Katla volcano and Myrdalsjokull.

• Book covers all aspects of the ice cap and volcano dynamics
• Comprehensive reviews with updated results
• Editors and authors are well established scientists with research experience from Myrdalsjokull
• Standard reference work for Myrdalsjokull
