Table 1. Grounded ice retreat, ice discharge, and mean mass balance for six glacier categories and three time periods: 1992–1997, 1998–2007, and 2008–2017.

The first four categories pertain to glaciers terminating in DW, on CR, in SC (<100-m depth), and with FE. The final two categories pertain to glaciers already in an SR, and NC glaciers with no ocean and bathymetry data.
