Dear David Herning et al.,

Thank you for submitting your manuscript “Response of biological productivity to North Atlantic marine front migration during the Holocene” to Climate of the Past, and for your response to the reviewers’ comments.

Based on the reviewers’ comments and your responses I would like to invite you to submit a revised version of the manuscript, where your responses to the reviewers’ comments are implemented. Please make it visible through track-changes where and what changes you have done in the revised manuscript.

I would suggest to add a paragraph discussing how your results relates to the more regional changes taking place through the Holocene. Are for instance your frontal changes associated with general front movements in the Nordic Seas, or is it solely a local phenomenon? Are the changes associate with major climatic or oceanographic events?

Thanks again for submitting your manuscript to CP. I will look forward to seeing the revised version

Best regards,

Dear David J. Harning and co-authors,

Tank you very much for your rapid response. I am pleased to accept your manuscript for publication subject to technical correction. I will look forward to seeing you paper published.

I would like you to add a newer reference to your oceanography description starting at line 45, in line with your more up to date presentation of the modern oceanography provided later on. You refer to papers from 1962 and 1981 and that is fine, but since then there has been 40-60 years of oceanographic studies in this area, adding knowledge. I think this should be acknowledged as well.

Thanks for publishing your work in Climate of the Past.

Best regards,
Bjørg Risebrobakken
