In this study, we use a combined biomarker and macrofossil approach to reconstruct the Holocene climate history recorded in Trifna Sø, Skallingen area, eastern North Greenland....

This dataset describes two 17 m long sediment cores taken from beneath two thermokarst lakes in the Yukechi Alas, Central Yakutia, Russia. The first core was taken from below an...

Endmember samples were collected and analyzed to determine the sources of organic material in the river suspended sediment. Endmembers include soil, leaf litter, and floodplain...

This dataset comprises plant wax n-alkane chain length concentrations and C25-C35 relative abundances of 209 plant specimens from two Kenyan C3-dominated ecosystems,...

An 8.6 million year reconstruction of paleotemperatures and paleovegetation from Lake Baikal, Russia, derived from Baikal Drilling Project core materials. This dataset also...

n-alkanes concentrations were extracted and purified with wet chemical methods (details in publication) and quantified by an internal standard (squalene) using a GC-FID
