We present a compilation of 117 time series δ<sup>13</sup>C records from Cibicides wuellerstorfi spanning the last deglaciation (20–6 kyr) and well-suited for reconstructing large-scale carbon cycle changes, especially for comparison with isotope-enabled carbon cycle models. The age models for the δ<sup>13</sup>C records are derived from regional planktic radiocarbon compilations (Stern and Lisiecki, 2014). The δ<sup>13</sup>C records were stacked in nine different regions and then combined using volume-weighted averages to create intermediate, deep, and global δ<sup>13</sup>C stacks. These benthic δ<sup>13</sup>C stacks are used to reconstruct mean changes in the size of the terrestrial biosphere and deep ocean carbon storage. The timing of change in global mean δ<sup>13</sup>C is interpreted to indicate terrestrial biosphere expansion from 19–6 ka. The δ<sup>13</sup>C gradient between the intermediate and deep ocean, which we interpret as a proxy for deep ocean carbon storage, matches the pattern of atmospheric CO<sub>2</sub> change observed in ice core records. The presence of signals associated with the terrestrial biosphere and atmospheric CO<sub>2</sub> indicates that the compiled δ<sup>13</sup>C records have sufficient spatial coverage and time resolution to accurately reconstruct large-scale carbon cycle changes during the glacial termination.
