|---|---|---|
| 10 m | 163 km² | 0.4% |
| 20 m | 268 km² | 0.6% |
| 50 m | 523 km² | 1.2% |
| 80 m | 723 km² | 1.7% |
| 120 m | 976 km² | 2.3% |
| 200 m | 1,508 km² | 3.5% |
| 500 m | 10,478 km² | 24.4% |
| 1,000 m | 42,754 km² | 99.4% |
| 2,000 m | 42,992 km² | 100% |

Frequently asked questions
How deep is the Prydz Bay?
On average about 589 m in the GEBCO grid (the middle value is 623 m). The deepest cell inside its outline is 1,402 m, at 68.94° S, 77.33° E.
How big is the Prydz Bay?
About 42,992 km² of water inside its Natural Earth outline, counted from the grid cells that are below sea level.
How much of the Prydz Bay would be land if sea level dropped?
With the sea 50 m lower, about 523 km² (1.2%) 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.
