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

Palaeogeography, Palaeoclimatology, Palaeoecology, 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.

Co-variation of crenarchaeol and branched GDGTs in globally-distributed marine and freshwater sedimentary archives [PDF]

Global and Planetary Change, 2012
Two major types of glycerol dialkyl glycerol tetraethers (GDGTs) are commonly used in paleoecological and paleoclimatological reconstructions: isoprenoidal and branched GDGTs.

Distributions of branched GDGTs in soils and lake sediments from western Uganda: Implications for a lacustrine paleothermometer

Organic Geochemistry, 2011
Bacterially produced branched glycerol dialkyl glycerol tetraethers (GDGTs) are ubiquitous in soils and lake sediments and can potentially be used to reconstruct past temperatures.

Influence of lake water pH and alkalinity on the distribution of core and intact polar branched glycerol dialkyl glycerol tetraethers (GDGTs) in lakes

Organic Geochemistry, 2013
Branched glycerol dialkyl glycerol tetraethers (GDGTs) are bacterial membrane lipids, ubiquitously present in soils and peat bogs, as well as in rivers, lakes and lake sediments.

Effects of a short-term experimental microclimate warming on the abundance and distribution of branched GDGTs in a French peatland

Geochimica Et Cosmochimica Acta, 2013
International audienceBranched glycerol dialkyl glycerol tetraethers (GDGTs) are complex lipids of high molecular weight, recently discovered in soils and increasingly used as palaeoclimate proxies.

Influence of soil pH on the abundance and distribution of core and intact polar lipid-derived branched GDGTs in soil

Organic Geochemistry, 2010
Branched glycerol dialkyl glycerol tetraether (GDGT) lipids occur in soils worldwide and are presumed to be produced by soil bacteria. They form the base of the MBT/CBT proxy (methylation of branched tetraethers/cyclisation of branched tetraethers) for ...

In situ production of branched glycerol dialkyl glycerol tetraethers in anoxic marine water columns

Marine Chemistry, 2014
Glycerol dialkyl glycerol tetraether (GDGT) compositions of suspended particulate matter in the water columns of two anoxic marine settings, the Black Sea and Cariaco Basin, were analyzed to better define the sources of GDGTs in marine environments.
