LIPOTHERM: A Calibration Framework for GDGT Paleothermometry Based on Machine Learning
Geochemistry, Geophysics, GeosystemsSST 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

Novel Extended Tetraether Lipids Found in a High‐CO2 Geyser [PDF]
Environmental Microbiology, Volume 28, Issue 3, March 2026.Characterisation of the archaeal lipidome of the CO2‐rich subsurface aquifer of the Geyser Andernach reveals novel extended tetraether lipids analogous to extended archaeols, likely produced by Candidatus Altiarchaeum, and potentially functioning as a membrane adaptation strategy to nutrient‐deprived conditions.

Environmental Controls on Crenarchaeol Distributions in Hydrothermal Springs [PDF]
Environmental Microbiology, Volume 28, Issue 2, February 2026.The optimal pH and temperature for crenarchaeol (a unique archaeal lipid) production in hydrothermal springs are 7.4°C and 46°C, respectively, which has important implications for archaeal evolution. Our study also indicates that pH is the most important environmental variable for archaeal lipid membrane compositions.

Enantioselective Total Synthesis of the Archaeal Lipid Parallel GDGT-0 [PDF]
, 2021 Archaeal glycerol dibiphytanyl glycerol tetraethers (GDGT) are some of the most unusual membrane lipids identified in nature. These amphiphiles are the major constituents of the membranes of numerous Archaea, some of which are extremophilic organisms ...

Benthic archaea as potential sources of tetraether membrane lipids in sediments across an oxygen minimum zone [PDF]
Biogeosciences, 2018 Benthic archaea comprise a significant part of the total prokaryotic biomass in marine sediments. Recent genomic surveys suggest they are largely involved in anaerobic processing of organic matter, but the distribution and abundance of these archaeal ...

Evaluation of the distributions of hydroxylated glycerol dibiphytanyl glycerol tetraethers (GDGTs) in Holocene Baltic Sea sediments for reconstruction of sea surface temperature: the effect of changing salinity [PDF]
Climate of the Past, 2022 Hydroxylated glycerol dibiphytanyl glycerol tetraethers (OH-GDGTs) produced by both marine and freshwater thaumarchaea are increasingly used for the reconstruction of past sea surface temperature (SST). They occur throughout the modern Baltic Sea, but it

Provenance of tetraether membrane lipids in a large temperate lake (Loch Lomond, UK): implications for glycerol dialkyl glycerol tetraether (GDGT)-based palaeothermometry [PDF]
Biogeosciences, 2014 The application of glycerol dialkyl glycerol tetraether (GDGT)-based palaeoenvironmental proxies, such as the branched vs. isoprenoidal tetratether (BIT) index, TEX86 and the MBT–CBT palaeothermometer, has lately been expanded to lacustrine sediments ...
