Evolution of a meteorite crater as a process of random displacements [PDF]
An examination of the ages and sizes of 114 terrestrial impact craters shows that their aging kinetics can be described by the diffusion laws. The macrodiffusion coefficient which determines random displacements of mineral masses on the Earth has a mean ...

Volcanically induced glacier collapses in southern Jan Mayen (Sør‐Jan), Norway
Boreas, EarlyView.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.

Boreas, EarlyView.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.

Boreas, EarlyView.Crater lakes in core regions of former ice sheets have the potential to preserve long‐term sedimentary archives that are otherwise rare in glaciated landscapes due to pervasive glacial erosion. Lake Wiyâshâkimî, an impact crater lake located in the inner core of the Québec‐Labrador Dome of the Laurentide Ice Sheet, provides a rare example of such a ...
