Glycerol dialkyl glycerol tetraether (GDGT) lipids are membrane lipids which were long
thought to be synthesized mainly by archaea, organisms thought to be limited to extreme …

Molecular organic geochemical proxies are increasingly being utilized to reconstruct past
environmental conditions as new tools continue to be discovered and developed. To date …

The development of methods using liquid chromatography coupled to mass spectrometry to
analyze glycerol dialkyl glycerol tetraethers (GDGTs) has substantially expanded the …

The early Eocene (56 to 48 million years ago) is inferred to have been the most recent time
that Earth's atmospheric CO 2 concentrations exceeded 1000 ppm. Global mean …

The alkenone–p CO2 methodology has been used to reconstruct the partial pressure of
ancient atmospheric carbon dioxide (p CO2) for the past 45 million years of Earth's history …

We propose a novel tracer for terrestrial organic carbon in sediments based on the analysis
of tetraether lipids using high-performance liquid chromatography/mass spectrometry …

It has recently been shown that membrane lipids of marine crenarchaeota, a ubiquitous and
abundant component of plankton, occur in relatively high concentrations in recent and …

Several studies have shown that there is a strong relationship between the distribution of
crenarchaeotal isoprenoid glycerol dibiphytanyl glycerol tetraethers (GDGTs) and sea …

Over the last years a novel group of branched glycerol dialkyl glycerol tetraether (GDGT)
membrane lipids has been discovered in peat bogs and soils. They consist of components …

We summarize the applications of molecular proxies in paleoclimatology. Marine molecular
records especially are proving to be of value but certain environmentally persistent …
