Comment:
Bulk sedimentary δ¹⁵N records of MD06-3067, MD98-2181, MD98-2177, MD97-2138, MD05-2920, and MD98-2162 and calculated northern and southern hemisphere stack records: Along with published records of MD01-2386 (Jia et al., 2011 doi:10.1029/2011gl050021; Jian et al., 2020 doi:10.1073/pnas.1915510117)) and U1486 (Lambert et al., 2022 doi:10.1016/j.quascirev.2021.107348), the δ¹⁵N records of MD06-3067, MD98-2181, MD98-2177, MD97-2138, MD05-2920, and MD98-2162 (all this study) were used to generate northern and southern hemisphere stack records. The separation of cores into a southern and northern hemisphere stack is based on hydrographic consistency, not latitude per se (for details see Kienast et al. (in revision)). Prior to the calculation of the δ¹⁵N stack records, all time series were interpolated to even time steps of 500 yrs. The northern and southern hemisphere stacks were then calculated as time-dependent mean of the individual records with the corresponding standard deviation.
