Although marine productivity is a key parameter in the global carbon cycle, reliable
estimation of productivity in ancient marine systems has proven difficult. In this study, we …

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 …

Understanding the processes influencing the sources and fate of organic matter (OM) in
estuaries is important for quantifying the contributions of carbon from land and rivers to the …

Quantifying past continental temperature changes is an important aspect of paleoclimate
research as it allows us to constrain the amplitude of natural variability, test predictive …

Large rivers connect the continents and the oceans, and corresponding material fluxes have
a global impact on marine biogeochemistry. The Yellow River transports vast quantities of …

The bacterial membrane lipid-based continental paleothermometer, the MBT/CBT or MBT′–
CBT proxy (methylation index of branched tetraethers/cyclization of branched tetraethers) …

Both Atlantic and Indian Ocean climate dynamics exert influence over tropical African
hydroclimate, producing complex patterns of convergence and precipitation. To isolate the …

Leaf wax components of terrestrial plants are an important source of biomass in the
geological records of soils, lakes and marine sediments. Relevant to the emerging use of …

About 3000 years ago, a major vegetation change occurred in Central Africa, when
rainforest trees were abruptly replaced by savannas. Up to this point, the consensus of the …

Revealing of the sources and distributions of sedimentary organic matter in the East China
Sea (ECS) is important for understanding its carbon cycle, which has significant temporal …
