The continental slope off Cape Hatteras, N.C. from approximately 36{degree} 00 minutes N to 35{degree} 20 minutes N is a region of relatively rapid sediment accumulation, organic matter deposition and subsequent remineralization. The measured fluxes are the highest reported for the slope off the eastern US Sediment accumulation rates range from 40 to 140 cm ky{sup -1}. Organic carbon deposition rates range from 3.5 to 7.4 moles C m{sup -2} yr{sup -1}. The areal coverage of this ''depocenter'' is probably controlled by interactions between physical oceanographic processes and the rugged topography of the seafloor. The organic matter deposited on the seafloor is primarily marine in origin and a mix of old and fresh particles. 73-93% of the depositing detritus is rapidly oxidized near the sediment/water interface. The controls on subsurface remineralization appear to be a complex function of the relative amount of metabolizable carbon delivered to the seabed both now and in the distant past (>=500ybp) and the extent of seabed irrigation. The age of DIC and CH{sub 4} produced within the seabed indicates that relatively young, reactive carbon is advected below the sediment surface and fuels subsurface remineralization. The stable isotopic composition of DIC produced within the seabed indicates the selective degradation of {sup 13}C-enriched fractions of the organic matter. The metabolizable fraction has a carbon isotopic signature of approx. -18{per_thousand};, while the organic matter that survives degradation and is buried has a d {sup 13}C closer to -20{per_thousand}.
