A late Pleistocene long pollen record from Lake Urmia, NW Iran [PDF]

, 2008
A palynological study based on two 100-m long cores from Lake Urmia in northwestern Iran provides a vegetation record spanning 200 ka, the longest pollen record for the continental interior of the Near East.

Changes in Freeze-Thaw Environments in a Cold Lake: Eliciting New Insights into the Activity and Composition of Bacterial Communities

Diversity
This study explored the dynamics of bacterial community composition, response to environmental factors, and co-occurrence network models across different habitats of Wuliangsuhai Lake during the glacial period.

Millennial-scale interaction between ice sheets and ocean circulation during marine isotope stage 100

Frontiers in Earth Science, 2016
Waxing/waning of the ice sheets and the associated change in thermohaline circulation have played an important role in global climate change since major continental ice sheets appeared in the northern hemisphere about 2.75 million years ago.

Understanding the mechanisms behind high glacial productivity in the southern Brazilian margin [PDF]

Climate of the Past, 2019
This study explores the mechanisms behind the high glacial productivity in the southern Brazilian margin (SBM) during the last 70 kyr using planktonic foraminifera assemblage and subsurface temperature information derived using the modern analogue

Pre-late Devensian high-arctic marine deposits in SW Scotland [PDF]

, 2010
We present new interpretations of Digital Elevation Model (DEM) data and marine fossils collected from three sites on the Rhins of Galloway which, contrary to recent proposals, suggest that the landforms and deposits of the region do not represent ...

Relationship between continental chemical weathering trends in the North China Basin and the high-latitude glacial cycles from the Late Carboniferous to the Early Permian

Meitian dizhi yu kantan
Objective and Methods The Late Paleozoic Ice Age (LPIA; ca. 360‒254 Ma), the only period recording the transition from icehouse to greenhouse conditions throughout the geological history, can provide a deep-time perspective for glacier-environment ...

Vulnerability of mountain glaciers in China to climate change

Advances in Climate Change Research, 2015
Mountain glaciers in China are an important water source for both China and adjoining countries, and therefore their adaptation to glacier change is crucial in relation to maintaining populations.

A tropical speleothem record of glacial inception, the South American Summer Monsoon from 125 to 115 ka [PDF]

Climate of the Past, 2015
Relatively few marine or terrestrial paleoclimate studies have focused on glacial inception, the transition from an interglacial to a glacial climate state.

The Glacial Period [PDF]

Nature, 1881
PLEASE correct an error in the notice of my paper on the Glacial Period (NATURE, vol. xxiv. p. 364). It is on the western slope of New Zealand that the glaciers reach to the highest mean annual temperature (10° C., or 50° F.) as well as to the lowest level.
