Splice composition of the Leg 154 Site 927, adjusted for this study from Wilkens et al. (2017, DOI: 10.5194/cp-13-779-2017). The previously published splice composition: spliced MS: https://doi.org/10.1594/PANGAEA.871011 and splice composition: https://doi.org/10.1594/PANGAEA.871006) for the MIS KM5 (110.43 mcd to 119.79 mcd, 3095 to 3307 ka) have been modified to make the individual cores magnetic susceptibility records continuous and fit along the composite core. The dataset contains the samples labels, depth mbsf of these samples and corresponding depth in the composite core (mcd) for all the tops and bottoms of the sections composing the splice for the interval from 110.43 mcd to 119.79 mcd.
