| 10 m | 63 km² | 1.4% |
| 20 m | 109 km² | 2.4% |
| 50 m | 235 km² | 5.1% |
| 80 m | 358 km² | 7.8% |
| 120 m | 497 km² | 10.9% |
| 200 m | 790 km² | 17.3% |
| 500 m | 2,625 km² | 57.4% |
| 1,000 m | 4,551 km² | 99.6% |
| 2,000 m | 4,570 km² | 100% |

Frequently asked questions
How deep is the Hall Basin?
On average about 435 m in the GEBCO grid (the middle value is 474 m). The deepest cell inside its outline is 1,091 m, at 81.20° N, 61.79° W.
How big is the Hall Basin?
About 4,570 km² of water inside its Natural Earth outline, counted from the grid cells that are below sea level.
How much of the Hall Basin would be land if sea level dropped?
With the sea 10 m lower, about 63 km² (1.4%) of its water would be land. At 6,000 m lower, 100% would be. This is a simple bathtub model that lowers the sea evenly everywhere.
