Organic carbon in marine sediments is a critical component of the global carbon cycle, and
its degradation influences a wide range of phenomena, including the magnitude of carbon …

Quantifying the rates of biogeochemical processes in marine sediments is essential for
understanding global element cycles and climate change. Because organic matter …

The oxidative degradation of organic matter is a key process in the biogeochemical
functioning of the earth system. Quantitative models of organic matter degradation are …

For more than a decade I have taught a graduate-level course in marine sediment
geochemistry that covers many of the topics discussed in this book. The goal now is to …

One of the defining characteristics of a biomarker is the retention, during diagenesis, of
structural characteristics indicative of its original biogenic source (Peters and Moldowan …

The fatty acid biogeochemistry of a fjord-like bay in eastern Newfoundland, Canada, was
investigated to determine sources and fates of organic material. Samples of plankton …

Reductions in the thickness and extent of Antarctic ice shelves are triggering increased
discharge of marine-terminating glaciers. While the impacts of recent changes are well …

As organic matter produced in the euphotic zone of the ocean sinks through the
mesopelagic zone, its composition changes from one that is easily characterized by …

Organic and inorganic geochemical indicators were examined in a 3-m core collected from
the mesohaline region of Chesapeake Bay (CB) to determine how sources of organic matter …

Carbon mineralization of fresh and aged diatoms (Skeletonema costatum) and barley hay
(Hordeum vulgare) was followed for 23 to 35 d in sandy and silty sediment. By the use of a …
