Organic carbon burial in the Cape Hatteras ocean margins. Relationships with mineral surfaces

PDF Version Also Available for Download.

Description

This project examined controls on organic carbon preservation in ocean margin sediments around Cape Hatteras, USA. Grain size variation explained most variance in sedimentary organic carbon concentrations. Normalizing to grain surface areas allowed identification of areas of particularly high organic matter loading - i.e., the upper slope regions. Spatial variations in concentrations are influenced by redistribution of organoclay aggregates. This region has higher grain size-normalized organic carbon concentrations than any other ocean margin environment with an aerobic water column studied to date. Small scale variations in the Chesapeake Bay were also studied.
