OSTST

The 2025 Ocean Surface Topography Meeting will occur on 15-16 November 2025 in conjunction with the Sentinel-6B launch.

There will be two hybrid splinters on the Sentinel-6 Next Generation orbit discussion and the regional and global reference mission Cal/Val. Posters and oral presentations to these sessions are solicited. In addition, in-person poster submissions to any usual splinter sessions are encouraged, in particular, submissions to the Application Development for Operations splinter are highly encouraged. There will be an option for virtual presentations and posters to any splinters via the forum.
