Sustained North Atlantic warming drove anomalously intense MIS 11c interglacial
Abstract The Marine Isotope Stage (MIS) 11c interglacial and its preceding glacial
termination represent an enigmatically intense climate response to relatively weak insolation …

[HTML][HTML] Ice-sheet burial and erosion inferred from cosmogenic nuclide bedrock depth profiles: Implications for the glaciation history of northeastern Fennoscandia
JL Andersen, MF Knudsen, AP Stroeven… - Quaternary Science …, 2024 - Elsevier
In this study, we evaluate the application of shallow (< 2.5 m) cosmogenic depth profiles in
bedrock to constrain long-term ice-burial and erosion histories. Using Markov Chain Monte …

Evidence for ca. 1 Ga hypervelocity impact event found in northwest Greenland
There are likely many undiscovered impact structures on Earth, but several challenges
prevent their detection, including possible concealment beneath large ice sheets. In recent …

Plant, insect, and fungi fossils under the center of Greenland's ice sheet are evidence of ice-free times
The persistence and size of the Greenland Ice Sheet (GrIS) through the Pleistocene is
uncertain. This is important because reconstructing changes in the GrIS determines its …
