The aim of this study was to determine the relationship between the development of rush zones in small lakes and the utilization and condition of surrounding lands. Generally, the width of the helophyte zone increased along shores with gentle slopes (>5˚)

Volcanically induced glacier collapses in southern Jan Mayen (Sør‐Jan), Norway
A formerly unknown glacier totally covered with tephra was found in an area of Jan Mayen where no Holocene glaciation was known. This glacier and three others in the same area melted abruptly creating jökulhlaups due to volcanic activity impacting the glacier catchments at different times in the Holocene.

This study focuses on the deglaciation dynamics in the northeastern sector of the Iceland Ice Sheet, by investigating transverse ridges, together with glacifluvial and ice‐marginal landforms. The main emphasis is on the transverse ridges, which are primarily interpreted as ribbed moraines – the first to be described in Iceland.

De Geer moraines may act as valuable ice‐marginal indicators; however, to date, their variable mode of formation has presented challenges for this utility. Here, we present sedimentological and ground penetrating radar data of DGMs located in southwest Finland.

An inventory of subglacial overdeepenings in southern Germany and Austria
We present an inventory and morphometric characterization of >100 individual overdeepened basins in southern Germany and Austria compiled from heterogeneous sources. Arrangement and dimensions of overdeepenings are compared to those of their western Alpine counterparts, to catchment topographies and bedrock lithologies, and to modelled ice‐flow ...

This study contains a comprehensive regional analysis of the orientations of tunnel valleys, faults and salt structures in the North German Basin, aiming to identify correlations that might indicate a structural control on tunnel‐valley formation. A structural control on tunnel‐valley formation has been repeatedly postulated and correlations have been ...

Glacier evolution and environmental changes in the northern Jan‐Mayen from the early deglaciation and well into the Holocene are discussed. Results are based on a large chronological dataset (TCN and radiocarbon dates), integrated with field data on glacial landforms and sediments, including the use of GPR.
