New indices and calibrations derived from the distribution of crenarchaeal isoprenoid tetraether lipids: Implications for past sea surface temperature reconstructions
Abstract Several studies have shown that there is a strong relationship between the distribution of crenarchaeotal isoprenoid glycerol dibiphytanyl glycerol tetraethers (GDGTs) and sea surfaceExpand
Occurrence and abundance of 6-methyl branched glycerol dialkyl glycerol tetraethers in soils : Implications for palaeoclimate reconstruction
The distribution of branched glycerol dialkyl glycerol tetraethers (brGDGTs) in soils has been shown to correlate with the soil pH and the mean annual air temperature (MAT). This has been used toExpand
Global sediment core-top calibration of the TEX86 paleothermometer in the ocean
Abstract The TEX86 (TetraEther indeX of tetraethers consisting of 86 carbon atoms) paleothermometer is based on the relative distribution of archaeal lipids, i.e. isoprenoid glycerol dibiphytanylExpand
Last deglacial sea-surface temperature evolution in the Southeast Pacific compared to climate changes on the South American continent
Abstract Applying the alkenone method, we estimated sea-surface temperatures (SSTs) for the past 33 kyr in two marine sediment cores recovered from the continental slope off mid-latitude Chile. TheExpand
North Pacific and North Atlantic sea-surface temperature variability during the Holocene
Holocene climate variability is investigated in the North Pacific and North Atlantic realms, using alkenone-derived sea-surface temperature (SST) records as well as a millennial scale simulation withExpand
Holocene and Eemian sea surface temperature trends as revealed by alkenone and Mg/Ca paleothermometry
In this study we review a global set of alkenone- and foraminiferal Mg/Ca-derived sea surface temperatures (SST) records from the Holocene and compare them with a suite of published Eemian SSTExpand
Constraints on the application of the MBT/CBT palaeothermometer at high latitude environments (Svalbard, Norway).
Abstract Branched glycerol dialkyl glycerol tetraethers (GDGTs) are membrane lipids of unknown bacteria that are ubiquitous in soil and peat. Two indices based on the distribution of these lipids inExpand
Orbitally driven insolation forcing on Holocene climate trends: Evidence from alkenone data and climate modeling
A global spatial pattern of long-term sea surface temperature (SST) trends over the last 7000 years is explored using a comparison of alkenone-derived SST records with transient ensemble climateExpand
Arctic/North Atlantic Oscillation signature in Holocene sea surface temperature trends as obtained from alkenone data
[1] The variability in alkenone-derived sea surface temperatures (SSTs) in the North Atlantic realm shows that a continuous SST decrease in the northeast Atlantic from the early to the late HoloceneExpand
Long chain 1,13-and 1,15-diols as a potential proxy for palaeotemperature reconstruction
Although commonly reported in marine and freshwater environments, little is known about the biological sources of long chain alkyl 1,13- and 1,15-diols, and factors controlling their distributions.Expand
