Recent works have investigated use of the hydrogen isotopic composition of C 37 alkenones
(δD K37s, lipid biomarkers of certain haptophyte microalgae, as an independent …

Long-chain alkenones (LCK) of lacustrine surface sediments were analyzed in 37 lakes from
China. The results obtained were complemented by published data from 13 other Chinese …

Selected warm and cold water strains of the coccolithophorid Emiliania huxleyi and the
closely related species Gephyrocapsa oceanica were cultured under controlled temperature …

Abstract The Great Plains of North America often experience prolonged droughts that have
major economic and environmental impacts. Temperature reconstructions are thus crucial to …

The ratio of 37‐carbon diunsaturated to diunsaturated and triunsaturated alkenones (UK′
37) produced by some haptophytes is widely used as a proxy for past sea surface …

The microalga Emiliania huxleyi produces alkenone lipids that are important proxies for
estimating past sea surface temperatures. Field calibrations of this proxy are robust but …

Twenty-seven multicores, collected in late summer 2004 from coastal and inland marine
sites throughout SE Alaska (∼ 55 to 61° N), were analyzed for C37 to C39 alkenones of …

Alkenones are biomarkers produced solely by algae in the order Isochrysidales that have
been used to reconstruct sea surface temperature (SST) since the 1980s. However …

Haptophyte algae-derived long-chain C37-C39 alkenones and alkyl alkenoates were
analyzed in euphotic zone particulate matter collected over a 7 yr period at the Oceanic Flux …

The extent of unsaturation in long chain alkenones (LCKs) in lakes has potential for
quantitatively indicating paleotemperature in terrigenous environments. However, the …
