Huy04: Averaged delta18O records on the depth-derived age-model
In mcrucifix/pleistocene: Datasets of glacial cycles (ice and ocean)

Description Usage Format Details Source References Examples

Averaged delta18O records on the depth-derived age-model. Columns are depth-derived age, estimated one-standard-deviation agemodel uncertainty, average of all delta18O records, average of the benthic records, and average of the planktic records. Averages are weighted according to the sampling resolution of each record.
