- Description: In-situ sea surface temperature and salinity from the TSG installed on the L’Astrolabe vessel (IPEV)
- Period: 1993-2023
- Area: Southern Ocean between Hobart (Tasmania) and Dumont d’Urville -the French Antarctic base-

The delayed mode datasets are available for two periods: 1993-2002 & 2002-2023.
I. Delayed-mode data, 2002-2024
The data are freely downloadable here (see README.txt file for details)
Netcdf files are at the GOSUD format
The SR3 WOCE line is also shown (white dashed line)
II. Delayed-mode data, 1993-2002
The data are freely downloadable here
III. Other products
Data are also available on request.
