Plant succession on glacial moraines in the Arctic Brooks Range along a >125,000-year glacial chronosequence/toposequence

open access: yesArctic, Antarctic, and Alpine Research, 2023
Widespread glacial retreat is now occurring in many arctic mountain ranges, yet little is known about primary succession following deglaciation in these settings.

Eskers and bedrock gorges (tunnel valleys) in the Pakasaivo area, western Finnish Lapland [PDF]

open access: yesBulletin of the Geological Society of Finland, 2003
Studies of the deglaciation of the last Scandinavian Ice Sheet, including the behavior of the ice sheet and meltwater activity, were conducted in the vicinity of the Pakasaivo canyon lake, located in western Finnish Lapland.

Evaluating the Relationship Between the Area and Latitude of Large Igneous Provinces and Earth's Long‐Term Climate State

open access: yesGeophysical Monograph Series, Page 153-168., 2021

Exploring the links between Large Igneous Provinces and dramatic environmental impact

An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

Marine‐Calibrated Chronology of Southern Laurentide Ice Sheet Advance and Retreat: ∼2,000‐Year Cycles Paced by Meltwater–Climate Feedback

open access: yesGeophysical Research Letters, 2023
Climatic warming following the Last Glacial Maximum caused the southern Laurentide Ice Sheet (LIS) to begin ∼2,000‐year cycles of retreat and readvance whose cause remains ambiguous.

The Last Deglaciation in the Southern Ocean [PDF]

open access: yesPaleoceanography, 1989
The isotopic and micropaleontological deglacial records of three deep‐sea cores from 44°S to 55°S have been dated by accelerator mass spectrometry. The available records did not allow accurate dating of the initiation of the deglaciation. By 13,000 years B.P., sea surface temperatures reached values similar to the present values.

Deglaciation of the North Cascade Range, Washington and British Columbia, from the Last Glacial Maximum to the Holocene

open access: yesCuadernos de Investigación Geográfica, 2017
Glacial retreat from the North Cascade Range after the Last Glacial Maximum (LGM) at approximately 21 ka until the end of the Pleistocene at 11.6 ka was complex and included both continental and alpine glaciers.

Some aspects of the last glaciation in the Mazury Lake District (north-eastern Poland)

open access: yesActa Palaeobotanica, 2013
The morphology of the Mazury Lake District (north-eastern Poland) dates from 24-19 ka (main stadial of the youngest Vistulian glaciation). During this last glacial maximum (MIS 2) a belt with lacustrine basins was formed when the ice sheet retreated at ...

Permafrost-carbon mobilization in Beringia caused by deglacial meltwater runoff, sea-level rise and warming

open access: yesEnvironmental Research Letters, 2019
During the last deglaciation (18–8 kyr BP), shelf flooding and warming presumably led to a large-scale decomposition of permafrost soils in the mid-to-high latitudes of the Northern Hemisphere.

Glacial geomorphology between Lake Vänern and Lake Vättern, southern Sweden

open access: yesJournal of Maps, 2020
The glacial geomorphology between the lakes Vänern and Vättern is presented on a 1:220,000 scale, LiDAR-based map covering approximately 18,000 km2.

Ocean (De)oxygenation Across the Last Deglaciation: Insights for the Future [PDF]

open access: yesOceanography, 2014
Anthropogenic warming is expected to drive oxygen out of the ocean as the water temperature rises and the rate of exchange between subsurface waters and the atmosphere slows due to enhanced upper ocean density stratification.
