Terrestrial plant biomarkers and their carbon isotopes provide insights into carbon cycling,
paleovegetation and paleoclimate, ranging in scale from local to global. Over the past …

Event deposits in lake sediments provide invaluable chronicles of geodynamic and climatic
natural hazards on multi-millennial timescales. Sediment archives are particularly useful for …

Measurements of dissolved methane in the ocean have been available for only about 50
years. Methane measurements in sediments, where concentrations are millimolar, were first …

Kerogen, commonly defined as the insoluble macromolecular organic matter (OM)
dispersed in sedimentary rocks, is by far the most abundant form of OM on Earth. This fossil …

The burial of organic matter (OM) in marine sediments represents the major link between
“active” surface pools of carbon in the oceans, atmosphere, on land, and in marine …

Microalgae are major sources of lipids in lacustrine and marine environments. This paper
provides a review of some recent advances in our knowledge of the wide variety of lipid …

Molecular organic geochemical proxies are increasingly being utilized to reconstruct past
environmental conditions as new tools continue to be discovered and developed. To date …

Marine dissolved organic matter (DOM) is a complex mixture of molecules found throughout
the world's oceans. It plays a key role in the export, distribution, and sequestration of carbon …

Terrestrial vegetation and soils hold three times more carbon than the atmosphere. Much
debate concerns how anthropogenic activity will perturb these surface reservoirs, potentially …

The term" carbon cycle" is normally thought to mean those processes that govern the
present-day transfer of carbon between life, the atmosphere, and the oceans. This book …
