Table 2.
Total ice cover (km2) for the seven maps (Table S1) allows calculation of the percent and annual percentage change in ice cover for each observational period (i.e., calculated relative to the previous map) along with the percentage of total ice cover lost from 1912 to 2007
| Map year | Area, km2 | No. years | % Area change per observation period | Annual rate of % area change per observation period (% yr−1) | % Area change since 1912 |

| 2007.8 | 1.851 | 1.7 | −4.1 | −2.4 | −84.65 |
| 2006.1 | 1.930 | 6.0 | −23.3 | −3.9 | |
| 2000.1 | 2.516 | 10.2 | −23.9 | −2.3 | |
| 1989.9 | 3.305 | 13.8 | −20.8 | −1.5 | |
