The observational data were collected by Australian, Japanese, and United States nationally funded programs that contribute to GO-SHIP (www.go-ship.org). We thank all scientific and ship personnel who enabled the collection of these data. BMS, SEW, and BT were supported by the Australian Climate Change Science Program, funded jointly by the Department of Climate Change and Energy Efficiency and CSIRO. Funding for AM was provided through NOAA Grant NA110AR4310063. The comments of two reviewers greatly improved the manuscript.
