Compiled marine radiocarbon data from the global ocean, derived from planktonic/benthic foraminifera and corals, spanning the last deglaciation, with associated calendar ages that are independently derived and/or are consistent with the Marine20 radiocarbon calibration curve. The data have been screened and include data flags pertaining to anomalous values (e.g. negative offsets relative to the contemporary atmosphere), low sedimentation rates <2 cm/kyr, and/or deviations from dominant regional-temporal trends. The data are further grouped by ocean basin, and according to their associated calendar ages as belonging to a succession of time slices across the last deglaciation: the Last Glacial Maximum (LGM), Heinrich Stadial 1 (HS1), the Bolling-Allerod (BA), the Younger Dryas, the Early Holocene (7-11ka BP), and the late Holocene (<6 ka BP).
