Impact of non-thermal variables on hydroxylated GDGT distributions around Iceland
Archaeal isoprenoid glycerol dibiphytanyl glycerol tetraethers (GDGTs) preserved in sediments are popular tools for the reconstruction of past temperature in the global ocean. Whereas the most common GDGTs have been well studied through environmental and

Abstract The Younger Dryas (YD, 12,900–11,700 years before present) event offers a key opportunity to investigate climate system responses to abrupt perturbations, yet regional hydroclimate responses in northeastern China remain debated. Here we reconstruct the spatial fingerprint of YD hydroclimate variability using a comprehensive fossil pollen data ...

Seasonality of archaeal lipid flux and GDGT-based thermometry in sinking particles of high-latitude oceans: Fram Strait (79° N) and Antarctic Polar Front (50° S) [PDF]
The relative abundance of individual archaeal membrane lipids, namely of glycerol dialkyl glycerol tetraethers (GDGTs) with different numbers of cyclopentane rings, varies with temperature, which enables their use as a paleotemperature proxy index.

An Early Miocene Lowland on the Northeastern Tibetan Plateau
The northeastern Tibetan Plateau (NE TP) has long been thought to be the last part of the Plateau to be raised, but this assumption has been challenged by recent analyses of fossil leaf energy, which have pointed to the possibility that the present ...

LIPOTHERM: A Calibration Framework for GDGT Paleothermometry Based on Machine Learning
Abstract SST reconstruction from glycerol dialkyl glycerol tetraethers (GDGT) preserved in marine sediments is an important tool in quantitative paleoclimatology. These reconstructions require calibration frameworks that provide mapping between sediment GDGT data and temperature values.

Distribution of tetraether lipids in agricultural soils – differentiation between paddy and upland management [PDF]
Rice paddies constitute almost a fifth of global cropland and provide more than half of the world's population with staple food. At the same time, they are a major source of methane and therewith significantly contribute to the current warming of Earth's

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