AllIGATR: A Multi‐Dimensional Approach for Marine Archaeal Lipid‐Based Paleothermometry

Paleoceanography and Paleoclimatology, Volume 41, Issue 10, October 2026.
Abstract Archaeal glycerol dibiphytanyl glycerol tetraether membrane lipids (GDGTs) are ubiquitous in marine sediments. The number of ring structures in six specific GDGTs varies with seawater temperature, leading to their use in paleothermometry. GDGT temperature dependence is typically quantified in TEX86.

A Shallow‐Marine Ecosystem Before Initial Tibetan Plateau Uplift

Geophysical Research Letters, Volume 53, Issue 18, 28 September 2026.
Abstract The uplift of the Tibetan Plateau profoundly influences global atmospheric circulation, sediment transport, and biodiversity, but its pre‐uplift marine paleoenvironment remains poorly understood. Here we report the first discovery of an in situ benthic fossil assemblage from the Puga area in central Tibet, which was deposited on a shallow ...

Reconstruction of a paleotemperature record from 0.3-3.7 ka for subtropical South China using lacustrine branched GDGTs from Huguangyan Maar

, 2015
The concentrations of glycerol dialkyl glycerol tetraethers (GDGTs) in catchment soils, suspended particulate matter (SPM), lake bottom sediments, and sediment cores from Huguangyan Maar, subtropical South China, were investigated.

Zoning of neocomian reservoirs of the Koltogor mezodepression and its fraiming structures by generation and accumulation density of Bazhenov oil

Известия Томского политехнического университета: Инжиниринг георесурсов, 2018
The relevance of the research is caused by the need to reproduce and expand the resource foundation of oilfields in Tomsk region. The aim of the research is to identify the priority zones for exploration and development of Neocomian oil-gas complex in ...

Ecological and Hydrological Modulation of Land Surface Temperature in the East Asian Monsoon Margin During Pliocene‐Pleistocene Global Cooling

Geophysical Research Letters, Volume 53, Issue 18, 28 September 2026.
Abstract The response of terrestrial climate to future warming remains debated. The Pliocene, with CO2 levels similar to today, is an important analog for the future. The East Asian monsoon marginal region is one of the most climate sensitive regions on Earth. Based on contemporaneous aeolian sediments and aquatic‐influenced alluvial sediments from the

Boron Isotope Evidence for Reduced Ventilation of the Deep Arctic Ocean During the Last Glacial Period

Paleoceanography and Paleoclimatology, Volume 41, Issue 9, September 2026.
Abstract Understanding the ventilation of the deep ocean, where most ocean carbon is stored, is essential to understanding how changes to ocean carbon budgets contribute to climate change. In the Arctic Ocean, shifts in ice cover, stratification and temperature are likely to impact carbon sequestration in the ocean interior.

Temperature exerts no influence on organic matter δ¹³C of surface soil along the 400 mm isopleth of mean annual precipitation in China [PDF]

Biogeosciences, 2016
Soil organic carbon is the largest pool of carbon in the terrestrial ecosystem, and its isotopic composition is affected by a number of factors. However, the influence of environmental factors, especially temperature, on soil organic carbon isotope ...

Extinct Species Unearth Bergmann's Rule in Canidae

Journal of Biogeography, Volume 53, Issue 9, September 2026.
ABSTRACT Aim Interspecific patterns of Bergmann's rule may be concealed by species extinctions within clades. We evaluate whether incorporating extinct species and paleoenvironmental information improves the detection of Bergmann's rule in the family Canidae, and test whether temperature and net primary productivity (NPP) explain interspecific ...

Sensitivity to species selection indicates the effect of nuisance variables on marine microfossil transfer functions [PDF]

Climate of the Past, 2019
The species composition of many groups of marine plankton appears well predicted by sea surface temperature (SST). Consequently, fossil plankton assemblages have been widely used to reconstruct past SST. Most applications of this approach make use of the
