Der erste Fund von Kieselgur in Schleswig—Holstein bei Brokenlande, südlich von Neumünster (Mit einem Beitrag zur Biostratigraphe des „Saale-Spätglazials“) [PDF]

open access: yesEiszeitalter und Gegenwart, 1967
Pollenanalytical studies of diatomaceous earth (Kieselgur) discovered for the first time in Schleswig-Holstein (south of Neumünster) indicate a firm Eemian Interglacial date.

Evaluating the variability of glacial lakes in the Kyrgyz and Teskey ranges, Tien Shan

open access: yesFrontiers in Earth Science, 2022
The northern Tien Shan Mountains are one of the most hazardous areas in Kyrgyzstan due to frequent glacial lake outburst floods (GLOFs). The current status of glacial lakes in this region has not been reported in recent years.

Bifurcations and strange nonchaotic attractors in a phase oscillator model of glacial-interglacial cycles [PDF]

open access: yesPhysica D: Nonlinear Phenomena, Volume 306, 15 June 2015, Pages 25-33, 2015
Glacial-interglacial cycles are large variations in continental ice mass and greenhouse gases, which have dominated climate variability over the Quaternary. The dominant periodicity of the cycles is $\sim $40 kyr before the so-called middle Pleistocene transition between $\sim$1.2 and $\sim$0.7 Myr ago, and it is $\sim $100 kyr after the transition. In

Mitochondrial DNA signals of late glacial recolonization of Europe from near Eastern refugia [PDF]

open access: yes, 2012
Human populations, along with those of many other species, are thought to have contracted into a number of refuge areas at the height of the last Ice Age.

Characterization of Long-Time Series Variation of Glacial Lakes in Southwestern Tibet: A Case Study in the Nyalam County

open access: yesRemote Sensing, 2022
Glacial lakes are important freshwater resources in southern Tibet. However, glacial lake outburst floods have significantly jeopardized the safety of local residents. To better understand the changes in glacial lakes in response to climate change, it is

Simulating Marine Isotope Stage 7 with a coupled climate–ice sheet model [PDF]

open access: yesClimate of the Past, 2020
It is widely accepted that orbital variations are responsible for the generation of glacial cycles during the late Pleistocene. However, the relative contributions of the orbital forcing compared to CO2 variations and other feedback mechanisms causing ...

Spatio-Temporal Distribution Characteristics of Glacial Lakes in the Altai Mountains with Climate Change from 2000 to 2020

open access: yesRemote Sensing, 2023
The evolution of a glacial lake is a true reflection of glacial and climatic change. Currently, the study of glacial lakes in the Altai Mountains is mainly concerned with the application of high-resolution remote sensing images to monitor and evaluate ...

Patterns in glacial-earthquake activity around Greenland, 2011–13

open access: yesJournal of Glaciology, 2017
Glacial earthquakes are caused by large iceberg calving events, which are an important mechanism for mass loss from the Greenland ice sheet. The number of glacial earthquakes in Greenland has increased sixfold over the past two decades.

Influence of external forcings on abrupt millennial-scale climate changes: a statistical modelling study [PDF]

open access: yesClimate Dynamics (First Online: 21 July 2016), 2015
The last glacial period was punctuated by a series of abrupt climate shifts, the so-called Dansgaard-Oeschger (DO) events. The frequency of DO events varied in time, supposedly because of changes in background climate conditions. Here, the influence of external forcings on DO events is investigated with statistical modelling.

Atmospheric 14C/12C changes during the last glacial period from Hulu Cave

open access: yesScience, 2018
The whole story An accurate, precise record of the carbon-14 (14C) content of the atmosphere is important for developing chronologies in climate change, archaeology, and many other disciplines. Cheng et al.
