Notes: DBD represents the average of the dry bulk densities (DBD) measured on discrete samples for each interval of apparently constant sedimentation. * = linear sedimentation rate (LSR) does not match the slope calculated using the endpoints of each interval as listed because the LSR reported was estimated from a linear fit to all biostratigraphic and paleomagnetic datums within each interval of apparently constant sedimentation. MAR = mass accumulation rate.
