This study on amino acid geochronology from foraminifera from three sediment cores is a valuable contribution, providing useful additional data from the Arctic region. The reviewers' comments have been responded to positively and the altered discussion increases the wider significance of the results. The paper is therefore accepted for publication in Geochronology, with only minor technical corrections, listed below.

Abstract line 24: it should be "...marine oxygen isotope stage (MIS)...
Introduction line 47: the accepted SI unit is "a" rather than "yr", so this should be "mm / ka".
line 50: no need for the comma after "thus".
line 57: add "have" before "reignited".
Line 59-60: no need to add (N. pachyderma) after the full name in these cases, as it is implicit that after this point the abbreviated genus names will refer to genera already mentioned.
Line 65-66: bracket out part of the sentence for clarity: I suggest ...dating methods (such as radiocarbon dating and correlations with the orbitally tuned, stacked oxygen isotope record (Martinson et al., 1987)), yet for the past....
M&M: Line 111: Add "The" before "ability".
Results: Line 172: Add comma after "excluded".
Line 183-4: change to "despite only 35% of all subsamples being taken from this core."
Discussion: Line 232: change "however," for "but".
Line 236: Add "However" so that it reads "However the small number (7)...".
Appendix A, line 387: change to "...depth-age models: a starting node...".
Figure captions: line 576: change to "...the Arctic-specific age equation (Kaufman et al., 2008)..." as this is how the line is referred to in the figure.
Figure 5: change the key to "D/L Asp or Glu not within =/- 2sigma of the horizon mean", to make it clearer which data is being used.
Table 2 legend: line 588: no need to capitalise "Aspartic acid". Line 590: italicise the genus / species names.

Many thanks for your positive response to the reviewer comments and revised version of your manuscript. This is acceptable for publication in Geochronology subject to a few minor outstanding corrections of a purely technical nature, as outlined in communication from the Associate Editor. Hopefully these are acceptable to you, and we can proceed to publication of your research in our journal, where it is a welcome addition. May I take this opportunity to thank you for choosing to submit your work to Geochronology, and we hope you will consider us in future.

With best wishes,

Philippa
