List of data provided
---------------------------------------------------
Main assessment timeseries for GMSL change, OHC and ThSL. Timeseries are global integrals over the following vertical layers: 0-300 m; 0-700 m; 0-2000 m; 700-2000 m; > 2000 m; Full-depth.

This dataset are also used in the following figures:
