The importance of thermal boundary transitions on glacial geomorphology; mapping of ribbed/hummocky moraine and streamlined terrain from LiDAR, over Småland, South Sweden
(2015) In GFF 137(4). p.252-283- Abstract
- In this paper we synthesise previous sedimentological studies and new, high resolution, digital elevation models from southern Småland to investigate the evolution of a deglacial landscape. Starting approximately at the deglacial highest shoreline, there is a 20-40 km wide zone of ribbed and hummocky moraine that can be connected to the predominantly subaqueous Göteborg moraine. North of this there is a dramatic shift into streamlined terrain. Based on sedimentological investigations we conclude that these zones represent a sub/supraglacial stagnant-ice landsystem, followed by a subglacial active ice landsystem, which during their formations had very different thermal and process regimes along the ice-bed interface (freezing on/frozen...

New observations derived from high resolution, LiDAR digital elevation models reveals patterns of erosional/depositional and morphostratigraphic relationships that have not previously been observed, opening up gateways for future research.
