Shifts in the hydrogen stable isotopic composition (2H/1H ratio) of lipids relative to water
(lipid/water 2H-fractionation) at natural abundances reflect different sources of the central …

Abstract Hydrogen isotope ratios (2 H/1 H or δ 2 H) were measured in lipid biomarkers from
algal, plant and microbial sources in sediment cores from a lake and a peat bog on the …

The Messinian salinity crisis (MSC; 5.97–5.33 Ma) is an enigmatic episode of
paleoceanographic change, when kilometers-thick evaporite units were deposited in the …

The stable hydrogen isotope composition of persistent biomolecules is used as a
palaeohydrological proxy. While much previous work has focused on plant leaf wax-derived …

Phytoplankton play a key role in biogeochemical cycles, impacting atmospheric and aquatic
chemistry, food webs, and water quality. However, it remains challenging to reconstruct …

The analysis of carbon and hydrogen stable isotope ratios of lipids from natural products is
an integral component of research in Earth sciences. The isotopic composition of lipids from …

Salinity and temperature dictate the buoyancy of seawater, and by extension, ocean
circulation and heat transport. Yet there remain few widely applicable proxies for salinity with …

Sedimentary lipid biomarkers have become widely used tools for reconstructing past climatic
and ecological changes due to their ubiquitous occurrence in lake sediments. In particular …

Hydrogen isotope ratios (δ2H) represent an important natural tracer of metabolic processes,
but quantitative models of processes controlling H-fractionation in aquatic photosynthetic …

Sea surface salinity is an essential environmental parameter necessary to understand past
changes in global climate. However, reconstructing absolute salinity of the surface ocean …
