Preservation of elemental and isotopic source identification of sedimentary organic matter
TLDR
The amount and type of organic matter in the sediments of lakes and oceans contribute to their paleoenvironmental and paleoclimatological records as discussed by the authors, but only a small fraction of the initial aquatic organic matter survives destruction and alteration during sinking and sedimentation.About:

The Biomarker Guide
TL;DR: The second edition of The Biomarker Guide as mentioned in this paper provides a comprehensive account of the role that biomarker technology plays both in petroleum exploration and in understanding Earth history and processes.
Journal ArticleDOI
Organic geochemical proxies of paleoceanographic, paleolimnologic, and paleoclimatic processes
TL;DR: In this article, the organic matter content of sediments is inferred from bulk properties such as elemental compositions, carbon and nitrogen stable isotope ratios, Rock-Eval pyrolysis data, and organic petrography.
Journal ArticleDOI
Applications of organic geochemistry to paleolimnological reconstructions: a summary of examples from the Laurentian Great Lakes
TL;DR: 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 local ecosystems as discussed by the authors, and serve as proxies of organic matter delivery and accumulation.
Journal ArticleDOI
Lacustrine sedimentary organic matter records of Late Quaternary paleoclimates
TL;DR: For example, despite the extensive early diagenetic losses of organic matter in general and of some of its important biomarker compounds in particular, bulk identifiers appear to undergo minimal alteration after sedimentation as discussed by the authors.

Sediment Organic Matter
Philip A. Meyers,Jane L. Teranes +1 more
TL;DR: 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 of regional climate changes as mentioned in this paper.

Carbon Isotopes in PhotosynthesisFractionation techniques may reveal new aspects of carbon dynamics in plants
TL;DR: The fractionation of carbon isotopes that occurs during photosynthesis is one of the most useful techniques for investigating the efficiency of CO2 uptake and indicates that different strategies are needed for improving wateruse efficiency in different kinds of plants.

Particulate organic carbon flux in the oceans—surface productivity and oxygen utilization
TL;DR: In this paper, an empirical relationship was established that predicts organic carbon flux at any depth in the oceans below the base of the euphotic zone as a function of the mean net primary production rate at the surface and depth-dependent consumption.

Cenozoic evolution of Antarctic glaciation the Circum-Antarctic Ocean and their impact on global paleoceanography
TL;DR: Deep-sea drilling in the Antarctic region (Deep-Sea Drilling Project legs 28, 29, 35, and 36) has provided many new data about the development of circum-Antarctic circulation and closely related glacial evolution of Antarctica as discussed by the authors.

CN ratios in Pacific deep-sea sediments: Effect of inorganic ammonium and organic nitrogen compounds sorbed by clays
TL;DR: In this article, an analysis of organic carbon, total nitrogen, and inorganically bound ammonium (exchangeable and fixed ammonium) in two oxic deep-sea sediment cores from the Central Pacific Ocean revealed insufficiently high inorganic ammonium contents of these sediments to explain the low C/N ratios.
