These values include estimates of their uncertainty as determined by a bootstrapping technique. These values were calculated from the Pliocene and Quaternary timeslices of benthic stable carbon isotope gradients compiled as part of this study (doi:10.1594/PANGAEA.993230). These values give insights into how the storage of respired and disequilibrium carbon in the deep North Pacific has changed through time.

The mean of these values (Δδ13C982-NPAC) was considered to represent the mean difference between the NADW benthic δ13C and deep North Pacific benthic δ13C. Uncertainty in Δδ13C982-NPAC was estimated via bootstrapping. Δδ13C982-Site# values were randomly resampled 10,000 times with the random.choices function in Python. The N of the resampled distribution was equivalent to the number of sites with available data for a given interval. The mean values of these 10,000 randomly resampled distributions were then ordered from smallest to largest and the 250th, and 9750th values were taken as representative of the bounds of the 95% confidence interval.
