Suggestions for revision or reasons for rejection

The revised version of this manuscript is much improved, especially by the inclusion of the bootstrap analysis and the greater attention given to errors generally in the construction of the stack. It is, however, unfortunate that the authors have not propagated their newly-constructed uncertainty estimates through to their assessment of the sea-level contribution to benethic δ18Oc. Bootstrap samples could be used both in the spectral analysis and in their OLS regression to measure the uncertainty in statements such as "the sea level stack contains 47% as much 100-ka power". I would also recommend sampling uncertainty for the smoothing window and lag used with the OLS; failing to do so will yield overly precise parameter estimates.

Note also that the authors express concern about the bootstrap PCA oversmoothing; this should not necessarily be the case if the authors operate on individual bootstrap samples rather than on the aggregate statistics of the bootstrap estimate. (I.e., if the authors are interested in the maximum of sea level over 119-126 ka, they should look at the bootstrap distribution of maxima rather than the maximum of the bootstrap median.

Minor comments:

Page 3, line 14: See Creveling et al. 2015 (doi: 0.1016/j.quascirev.2015.01.003) for the GIA and tectonic correction to past interglacial highstand sea-level estimates.

Page 3, line 30: "of 8.7 ± 0.7 m for global mean sea level at the last interglacial" -- this is imprecisely stated, as the statements of Kopp et al. (2009) upon which the authors base their statement pertain to peak GMSL during the last interglacial, not GMSL over the entire interglacial.

Page 16, line 9: "To explain this transition" is a misplaced modifier.

Page 16, line 18: "during in glacial maxima" - not sure what the authors are referring to here. Clarify.
