Dear Dr. Ardiningsih,

Thank you very much for responding to the comments from four referees so carefully. I consider that most of the issues or concerns reaised by the referees have been resolved. Therefore, we would appreciate it very much if you could submit the latest version of your manuscript with point-by-point responses to the referees' comments through the BG website. Once we receive these files from you, we will send them to two out of the four referees at least for furhter review.

Again thank you for your nice efforts to improve the manuscript.

Kind regards,

Koji Suzuki
Associate Editor

Dear Dr. Ardiningsih,

We are delighted to inform you that your manuscript has been accepted by Biogeosciences. Before it is published, please correct the two issues raised by Dr. Jonathan Lauderdale (see below), although the first issue (i.e., section 2.3 heading) has been resolved in the manuscript with tracked changes.

Thank you again for choosing Biogeosciences as an outlet of your excellent work.

Kind regards,

Koji Suzuki
Associate Editor

Review of Ardiningsih et al “Fe-binding organic ligands in coastal and frontal regions of the western Antarctic Peninsula” by Jonathan Lauderdale, MIT.

In this revised manuscript, Ardiningsih and coauthors present trace metal and organic ligand observations from coastal, frontal, and open ocean waters off the western Antarctic Peninsula. The different water masses identified in these regions are influenced by different iron inputs and ligand supply/generation mechanisms, such as glacial melt water, sea-ice algae interactions, sediment resuspension, and phytoplankton bloom processes.

I still think this work was interesting and well written, and the paper has been improved since my last review - I would recommend publication.

Two minor edits I noticed were:
1) The section 2.3 heading, I think, includes the last sentence from the previous section by accident (pretty sure it should be “2.3 Analysis of Fe-binding ligands”?)
2) Line 213: “stations 70 and 72 below 200m” escaped the change to “stations A and B”.
