Table 2:
Summary of D values for the total GrIS and four distinct regions (see Fig. 3), including the estimated mean annual D in 2000, the maximum D over the 2000–2016 period, and the cumulative D anomaly (ΔD2000) relative to the 2000 estimate. All values are described in units of Gta−1. A negative value indicates a reduction in D relative to the 2000 value.
