Dataset abstract This data set contains salinity measurements from discrete seawater samples that were collected in the Southern Ocean (south of 30deg S) during the Antarctic Circumnavigation Expedition (ACE). 657 samples were collected during the period December 24th, 2016 and March 18th, 2017 in the Southern Ocean from the surface ocean using the ship's underway line (UW; 328 samples) and in vertical profiles using Niskin bottles mounted on the CTD rosette (273 samples). A few additional samples (56) were collected from a parallel cast with a trace-metal rosette, with a bucket, and as duplicates to ensure data quality. All samples were analyzed for their salinity and results are reported on the Practical Salinity Scale 1978 (PSS-78; Sea-Bird Electronics, Inc., 1989). Measurements were performed on a Guildline Autosal Laboratory Salinometer 8400(B) at CSIRO (Hobart, Australia) for samples collected during leg 1, and on a OPTIMARE Precision Salinometer (OPS) at the Alfred Wegener Institute (Bremerhaven, ... : This research was supported by Swiss National Science Foundation (SNSF) grant numbers PZ00P2_142684, P2EZP2_175162, and P400P2_186681, and a grant from the BNP Paribas Foundation. I.G. thanks FCT/ MCTES for the financial support to CESAM (UIDP/50017/2020+UIDB/50017/2020) through national funds. We thank Kendall Sherrin (CSIRO) for processing the leg 1 samples, and Susan Becker and Lynne Talley (Scripps) for lending us their sampling bottles. We thank Stefan Vogel for the Autosal cleaning/checking and logistics in Hobart and Gwenael Renard for assistance with samples/cargo handling in Bremerhaven. We thank Yvonne Firing and Rob Craft (NOC) for providing Autosal training. It would have not been possible to assemble this data set without their help. The Antarctic Circumnavigation Expedition was made possible by funding from the Swiss Polar Institute and Ferring Pharmaceuticals. ...
