Archaeal Tetraether Lipids as Tracers for Past Marine Environmental Change

Paleoceanography and Paleoclimatology, Volume 41, Issue 7, July 2026.
Abstract Archaea are single‐celled microorganisms that are abundant in marine environments and play a key role in the carbon and nitrogen cycles. Archaea can biosynthesize a wide variety of isoprenoid membrane lipids, including isoprenoid glycerol dibiphytanyl glycerol tetraethers (isoGDGTs).

Minimal Perturbation of the Global Mercury Cycle by the Paraná–Etendeka Large Igneous Province (PE–LIP) During the Onset of the Valanginian Weissert Event

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 7, July 2026.
Abstract The Valanginian positive carbon isotope excursion (Weissert Event, ca. 135 million years ago) documents a major global carbon cycle and climate perturbation. Radioisotopic dating suggests that this event was broadly contemporaneous with an interval of profoundly enhanced volcanic activity during the emplacement of the Paraná–Etendeka Large ...

Branched and isoprenoid tetraether (BIT) index, TEX86 and sea surface temperatures of IODP Hole 302-M0004A

, 2010
TEX86' rather than TEX86 was proposed to reconstruct SST for uppermost Paleocene strata of Core 302-4A-32X, as abundances of the glycerol dialkyl glycerol tetraether (GDGT) lipid containing three cyclopentanemoieties (GDGT-3) were unusually high.

Evidence for Limited Atmospheric CO2 Rise at the Miocene Climatic Optimum

Paleoceanography and Paleoclimatology, Volume 41, Issue 6, June 2026.
Abstract The Miocene Climatic Optimum (MCO; 16.9–14.7 Ma) was a relatively warm period with atmospheric CO2 averaging ∼500 μatm but CO2 change across its onset is poorly documented. We present a record of algal 13C‐fractionation covering the Early to Middle Miocene (∼18.5–15 Ma), with a gap at the MCO onset, from Ocean Drilling Program Site 959 in the ...

The TEX86 paleotemperature proxy

, 2020
The TEX86 paleothermometer is based upon the distribution of archaeal membrane lipids (“GDGTs”) in marine sediments. GDGTs are ubiquitous, abundant and relatively resistant to degradation; as such, the TEX86 paleothermometer has been used to reconstruct ...

Terrestrial Ecosystem Response to Changing Temperature and Seasonality in the Paleocene‐Eocene Thermal Maximum: Shallow Marine Records From the Salisbury Embayment, USA

Paleoceanography and Paleoclimatology, Volume 41, Issue 3, March 2026.
Abstract The Paleocene‐Eocene thermal maximum (PETM, ∼56 Ma) is marked by a massive and rapid rise in atmospheric CO2 and ∼5°C of global warming. It is globally characterized by a negative carbon isotope excursion (CIE), and, at least locally, is preceded by a pre‐onset excursion (POE).
