The limited number of surface mass balance (SMB) observations in the Antarctic inland hampers estimates of ice sheet contribution to global sea level and locations with million year-old ice. We present finely resolved SMB over the past three centuries in a low-accumulation region on Dome Fuji derive...

The limited number of surface mass balance (SMB) observations in the Antarctic inland hampers estimates of ice sheet contribution to global sea level and locations with million year-old ice. We present finely resolved SMB over the past three centuries in a low-accumulation region on Dome Fuji derived from 1100 km of microwave radar stratigraphy dated with a firn core to 20 m depth where depth hoar dominates. The regional-mean SMB over the past 264 years is estimated to 22.5+-3.3 kg m-2a-1, but with large local variability of up to 30%. We found that local SMB is negatively correlated with surface slope at scales of a few hundred meters, resulting in anomalous zones of low SMB which represent as much as 8-10% of the total SMB on the inland plateau if the SMB-slope relationship is more widely valid.
