4 Until now: 22 new cruises in the Southern Ocean About 10 more cruises to follow Also: 46 cruises from GLODAP as “master cruises” However, the uncorrected/not adjusted cruise data are used.

5 Southern Ocean: Region with least data Few repeat sections 231 Cross-over points, including those with “GLODAP” cruises (but more in the near future)

6 Summary of offsets for the SO Atl-Sector
