The morphosedimentary record of glacial to postglacial environmental changes in West Wiyâshâkimî impact crater lake and adjacent areas, northern Québec, Canada

Boreas
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

Sedimentology of core PS1423-2

, 1996
Investigations of the stratigraphy and facies within a 2.69m long gravity core (PS1423-2) from the southwestern Weddell Sea, Antarctica, indicate a significant change in the character of glaciomarine sedimentation since grounded ice withdrew from the ...

Evidence for a Middle Pleistocene glaciation of MIS 8 age in the southern North Sea

, 2005
In the coresof borehole 89/2, situated at 541 00 010N and 51 00 040E about 70 km north of the Frisian Islands in the southern North Sea, two diamictonsle vels are found at 770 and 100m below sea floor (i.e.

Pre-Late-Wisconsin Glacial History of the Naknek River Valley, Southwestern Alaska

, 1996
The lower Naknek River in southwestern Alaska dissects thick (~20m) exposures of Pleistocene glaciogenic sediments. The stratigraphy of the deposits and their physical, geochemical, mineralogical, and geochronological properties were studies to determine

Micromorphology of Last Glacial Maximum Grounding line sediments around the Antarctic Peninsula

, 2012
Sediments recovered from seven Last Glacial Maximum grounding lines sites, around the Antarctic Peninsula, were analyzed using micromorphology. This is the first evidence that grounding line sediments from around the Antarctic Peninsula have complex ...

Imaging Periglacial Stripes using Ground Penetrating Radar at the 'GRIM' training site, Grimes Graves, Breckland, Norfolk

, 2017
The geological structure of periglacial patterned ground made visible by heather ‘tiger’ stripes at the GRIM Military Training Site, Breckland, Norfolk was investigated using Ground Penetrating Radar. A tripartite deposit model comprising an upper pellet
