(2026, Science Advances). It consists of Last Millennium (750 CE to present) sea-surface and thermocline temperature data used to assess the strength of the Pacific Walker Circulation of the last millennium. Ages have been updated to Marine20 and generated, with age uncertainty, using geoChronR (McKay et al., 2021). See Hess et al.
