Deglaciation of Fennoscandia [PDF]

Quaternary Science Reviews, 2016
To provide a new reconstruction of the deglaciation of the Fennoscandian Ice Sheet, in the form of calendar-year time-slices, which are particularly useful for ice sheet modelling, we have compiled and synthesized published geomorphological data for eskers, ice-marginal formations, lineations, marginal meltwater channels, striae, ice-dammed lakes, and ...

The penultimate deglaciation: protocol for Paleoclimate Modelling Intercomparison Project (PMIP) phase 4 transient numerical simulations between 140 and 127 ka, version 1.0 [PDF]

Geoscientific Model Development, 2019
The penultimate deglaciation (PDG, ∼138–128 thousand years before present, hereafter ka) is the transition from the penultimate glacial maximum (PGM) to the Last Interglacial (LIG, ∼129–116 ka).

The last deglaciation of Alaska

Cuadernos de Investigación Geográfica, 2017
We review available chronologies that constrain the timing of glacier fluctuations during the last deglaciation in Alaska. We address three questions relating to the last glacial termination: (i) How did the timing of glacier recession relate to buildup ...

Deglaciation-enhanced mantle CO2 fluxes at Yellowstone imply positive climate feedback [PDF]

Nature Communications
Mantle melt generation in response to glacial unloading has been linked to enhanced magmatic volatile release in Iceland and global eruptive records. It is unclear whether this process is important in systems lacking evidence of enhanced eruptions.

Arthropod Food Webs in the Foreland of a Retreating Greenland Glacier: Integrating Molecular Gut Content Analysis With Structural Equation Modelling [PDF]

Ecology and Evolution
The Arctic has warmed nearly four times faster than the global average since 1979, resulting in rapid glacier retreat and exposing new glacier forelands. These forelands offer unique experimental settings to explore how global warming impacts ecosystems,

Deglaciation of the Laurentide Ice Sheet from the Last Glacial Maximum

Cuadernos de Investigación Geográfica, 2017
The last deglaciation of the Laurentide Ice Sheet (LIS) was associated with major reorganisations in the ocean-climate system and its retreat also represents a valuable analogue for understanding the rates and mechanisms of ice sheet collapse. This paper

Deglaciation of the Colorado Rocky Mountains following the Last Glacial Maximum

Cuadernos de Investigación Geográfica, 2017
The availability of almost 180 cosmogenic-radionuclide (CRN) surface-exposure ages from moraine boulders and glacially polished bedrock surfaces makes possible an assessment of the timing and character of the local Last Glacial Maximum (LLGM) and ...

Hydroclimate footprint of pan-Asian monsoon water isotope during the last deglaciation

Science Advances, 2021
Pan-Asian monsoon water isotope variability is found accompanied by a continental-scale hydroclimate footprint. Oxygen isotope speleothem records exhibit coherent variability over the pan-Asian summer monsoon (AM) region. The hydroclimatic representation

Ocean Response in Transient Simulations of the Last Deglaciation Dominated by Underlying Ice‐Sheet Reconstruction and Method of Meltwater Distribution

Geophysical Research Letters, 2022
The last deglaciation was characterized by drastic climate changes, most prominently melting ice sheets. Melting ice sheets have a significant impact on the atmospheric and oceanic circulation, due to changes in the topography and meltwater release into ...

On deglaciation between Pieksämäki and Pielavesi in central Finland [PDF]

Bulletin of the Geological Society of Finland, 1974
On the basis of four end moraine formations, some of them not known before, the phases of deglaciation between Pieksämäki and Pielavesi in central Finland have been described in this paper. The trend of these end moraines, other transverse formations and
