The 1759-1774 eruption of the Jorullo volcano in the Michoacán Guanajuato Volcanic Field (MGVF), Mexico, produced lavas that range in composition from basalt to basaltic...

The end-Guadalupian (middle Permian) mass extinction recorded the disappearance of shelf faunas such as fusulinids, small foraminifers, brachiopods, rugose corals which...

The Baltic Sea has had a complex salinity history since the last deglaciation. Here we show how distributions of alkenones and their dD values varied with past fluctuations in...

The bulk organic matter composition (total organic carbon (TOC) content and d13CTOC ) and composition of isoprenoid and branched glycerol dialkyl glycerol tetraethers (GDGT) in...

The Kolyma Water-Balance Station (KWBS) was the first in the world research hydrological watershed in continous permafrost area where water balance, hydrological regime and...

Rare earth elements (REE) total concentration and signature in soils are known to be impacted by successive soil-forming processes. So it can be used as probe of soil processes....

We investigated the potential for classification tree (CT) models to provide a further approach to paleo Arctic sea ice reconstruction through analysis of a suite of six highly...

High-resolution quantitative temperature records from continents covering glacial to interglacial transitions are scarce but important for understanding the climate system. We...

Bulk chemical composition and mineralogy were examined in three soil profiles and a deeper 11-meter profile weathering on a granite ridgeline under subtropical climate...

A dataset of annual freshwater ice phenology was compiled for the largest river (Danube) and the largest lake (Lake Balaton) in eastern-central Europe, extending regular river...

Seep carbonates provide excellent records of past seepage activities, and have been commonly considered to preserve primary, unaltered stable carbon isotope signatures. However,...

Geochemical analysis of the 14.4-m-thick lacustrine succession of the Lower Cretaceous Yixian Formation (Jehol Group) has yielded new insights concerning vertebrate mass...

Rare earth elements (REEs) and major ions were determined in rainwater samples collected from Guiyang in the acid rain impacted zone of Southwest China. The concentrations of...

On the Tibetan Plateau, applications of dD and d18O values in paleoclimate studies tend to be complicated due to multiple processes influencing isotopic compositions in...

The TEX86 is a widely used paleotemperature proxy based on isoprenoid glycerol dibiphytanyl glycerol tetraethers (GDGTs) produced by Thaumarchaeota. Archaeal membranes are...

In late 2014, a large, oxygen-rich salt water inflow entered the Baltic Sea and caused considerable changes in deep water oxygen concentrations. We studied the effects of the...

Nine nodules collected from throughout the deep North Pacific were analyzed for their mineralogy and major-element composition before and after leaching with Chester-Hughes...

Most permafrost is located in the Arctic, where frozen organic carbon makes it an important component of the global climate system. Despite the fact that the Arctic climate...

Pelagic clay and Mn nodules from DOMES sites in the North Pacific and a varved glacial lake deposit from Connecticut were analysed for Os concentration and isotopic composition...

Previous reconstructions of ice-sheet changes in Antarctica's Weddell Sea sector since the Last Glacial Maximum (LGM) at 19-23 (calibrated) cal. kyr B.P. suffered from large...
