The Tuupovaara end moraine in North Karelia, Eastern Finland - an ice-marginal formation of the same age as the Salpausselkä ridges [PDF]

open access: yesBulletin of the Geological Society of Finland, 1983
Described in this report is a previously for the most part unknown ice-marginal formation in the province of North Karelia extending from the parish of Värtsilä via Tohmajärvi and Tuupovaara to the parish of Ilomantsi.

Influence of the 1988 earthquake on glacierization and relief of the Tsambagarav massif (Western Mongolia)

open access: yesЛëд и снег, 2022
Early documentation of the consequences of the Tsambagarav earthquake happened on July 23, 1988 (M = 6.4) compiled by Soviet and Mongolian specialists allowed the authors, using the example of Tsambagarav (Mongolian Altai), to assess the impact of the ...

Abrupt climate changes of the last deglaciation detected in a Western Mediterranean forest record [PDF]

open access: yes, 2009
Abrupt changes in Western Mediterranean climate during the last deglaciation (20 to 6 cal ka BP) are detected in marine core MD95-2043 (Alboran Sea) through the investigation of high-resolution pollen data and pollen-based climate reconstructions by the ...

An ice-sheet scale comparison of eskers with modelled subglacial drainage routes [PDF]

open access: yes, 2015
Eskers record the signature of channelised meltwater drainage during deglaciation providing vital information on the nature and evolution of subglacial drainage.

CH4 and N2O fluctuations during the penultimate deglaciation [PDF]

open access: yes, 2021
Deglaciations are characterized by the largest natural changes in methane (CH4) and nitrous oxide (N2O) concentrations of the past 800 000 years. Reconstructions of millennial- to centennial-scale variability within these periods are mostly restricted to

Deglaciation and proglacial lakes [PDF]

open access: yesGeology Today, 2015
Glaciers and ice sheets are important constituents of the Earth's land surface. Current worldwide retreat of glaciers has implications for the environment and for civilisation. There are a range of geomorphic changes occurring in cold environments and it is anticipated that these will be accentuated as a consequence of climate change.

Rapid northern hemisphere ice sheet melting during the penultimate deglaciation [PDF]

open access: yes, 2022
The rate and consequences of future high latitude ice sheet retreat remain a major concern given ongoing anthropogenic warming. Here, new precisely dated stalagmite data from NW Iberia provide the first direct, high-resolution records of periods of rapid

Paraglacial Rock-Slope Failure Following Deglaciation in Western Norway [PDF]

open access: yes, 2020
The paraglacial framework describes the geomorphological response to glaciation and deglaciation, whereby non-renewable, metastable, glacially-conditioned sediment sources are progressively released by a range of nonglacial processes. These include slope

Atmospheric methane variability through the Last Glacial Maximum and deglaciation mainly controlled by tropical sources [PDF]

open access: yes, 2023
Constraining the causes of past atmospheric methane variability is important for understanding links between methane and climate. Abrupt methane changes during the last deglaciation have been intensely studied for this purpose, but the relative ...

Revisiting Western United States Hydroclimate During the Last Deglaciation

open access: yes, 2023
During the last ice age, the western United States was covered by large lakes, sustained partly by higher levels of precipitation. Increased rainfall was driven by the atmospheric circulation associated with the presence of large North American ice ...
