1. Sediment burialDEFINITION OF SEDIMENT C BURIAL: Deposition of C below the zone of bioturbation, oxygen, and resuspension where it is effectively sequestered for millennial time scales.Important to the global C cycle through the geologic carbon cycle - sediments are the point of entry iof reduced carbon into the geologic record. Related to O2 evolution in the atmosphere
2. TIME SCALE MISMATCHThe modern practice of C science is largely interested in determining the processes that result in the concentration of CO2 in the atmosphere NOW. Instantaneous, annual, decadal – NOT millennial ISSUE: Historic data is focused on the geologic timescaleISSUE: Exponential decay function
3. “What is the Sediment Burial term?” is the WRONG questionWhat processes are sediments involved in related to the modern C budgetSediment flux,Biogenic sedimentsWhat is the Carbon balance?Source of sedimentsLocation of depositsWhat is the sediment contribution the carbon budget in a section of ocean over a the period of a study. What is the contribution
