We thank Makio Honda and Shuichi Watanabe (JAMSTEC) for obtaining the optode data during the R/V Mirai cruise MR06–03. We also thank Yuichiro Kumamoto and Masahide Wakita (JAMSTEC) for analyzing the Winkler oxygen data from the R/V Mirai cruises. Comments by Taiyo Kobayashi (JAMSTEC) were helpful. We also thank Anders Tengberg (Göteborg University) and two anonymous reviewers for valuable comments, which improved the paper considerably.
