Organic geochemical proxies of paleoceanographic, paleolimnologic, and paleoclimatic processes
Abstract Organic matter constitutes a minor fraction of marine and freshwater sediments, yet its important contribution to the sedimentary record can be used to reconstruct marine and continentalExpand

Applications of organic geochemistry to paleolimnological reconstructions: a summary of examples from the Laurentian Great Lakes
The organic matter content of lake sediments contains information that helps to reconstruct past environmental conditions, evaluate histories of climate change, and assess impacts of humans on localExpand

Lacustrine organic geochemistry—an overview of indicators of organic matter sources and diagenesis in lake sediments
The factors affecting the amounts and types of organic matter in lacustrine sediments are summarized in this review, and synthesis, of published studies. Biota hving in the lake and in its watershedExpand

Lacustrine Sedimentary Organic Matter Records of Late Quaternary Paleoclimates
Identification of the sources of organic matter in sedimentary records provides important paleolimnologic information. As the types and abundances of plant life in and around lakes change, theExpand

Sediment Organic Matter
The organic matter content of lake sediments provides a variety of indicators, or proxies, that can be used to reconstruct paleoenvironments of lakes and their watersheds and to infer histories ofExpand

A multiple proxy and model study of Cretaceous upper ocean temperatures and atmospheric CO2 concentrations
foraminiferal d 18 O and Mg/Ca suggests that the ratio of magnesium to calcium in the Turonian-Coniacian ocean may have been lower than in the Albian-Cenomanian ocean, perhaps coincident with anExpand

Sedimentary geolipid records of historical changes in the watersheds and productivities of Lakes Ontario and Erie
The organic matter contents of sediments deposited in Lakes Erie and Ontario contribute to the record of changes in the lake watersheds and aquatic ecosystems which have resulted from EuropeanExpand

The late Miocene onset of high productivity in the Benguela Current upwelling system as part of a global pattern
Abstract We have examined the history of the elevated primary productivity associated with the Benguela Current upwelling system off southwest Africa using sediments from 7.5 to 4.8 Ma at OceanExpand

Lipid biomarkers in the Zoigê-Hongyuan peat deposit: Indicators of Holocene climate changes in West China
Abstract Lipid biomarkers extracted from a peat core obtained from the northeast edge of the Tibetan Plateau have provided a 13 kyr record of regional climate change. A period of warmer climateExpand

Perylene: an indicator of alteration processes or precursor materials?
Abstract Perylene is a polycyclic aromatic hydrocarbon (PAH) that is found pervasively in both marine and freshwater sediments, yet its origin remains obscure. We have explored relationships betweenExpand
