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 …

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 …

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 …

Understanding the fate of terrestrial organic carbon (C org) delivered to oceans by rivers is
critical for constraining models of biogeochemical cycling and Earth surface evolution. C org …

The future trajectory of greenhouse gas concentrations depends on interactions between
climate and the biogeosphere,. Thawing of Arctic permafrost could release significant …

Environmental context. On a global scale, soils store more carbon than plants or the
atmosphere. The cycling of this vast reservoir of reduced carbon is closely tied to variations …

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 …

The occurrence of pre-aged organic carbon (OC) in continental margin surface sediments is
a commonly observed phenomenon, yet the nature, sources, and causes of this aged OC …

The burial of terrestrial organic carbon (terrOC) in marine sediments contributes to the
regulation of atmospheric CO2 on geological timescales and may mitigate positive feedback …

The Amazon River spawns a vast mobile mudbelt extending∼ 1600km from the equator to
the Orinoco delta. Deposits along the Amazon–Guianas coastline are characterized by …
