| 10 m | 435 km² | 1.9% |
| 20 m | 602 km² | 2.6% |
| 50 m | 1,325 km² | 5.8% |
| 80 m | 2,237 km² | 9.8% |
| 120 m | 3,638 km² | 15.9% |
| 200 m | 7,772 km² | 33.9% |
| 500 m | 18,097 km² | 78.9% |
| 1,000 m | 22,523 km² | 98.2% |
| 2,000 m | 22,940 km² | 100% |
| 3,000 m | 22,940 km² | 100% |
| 4,000 m | 22,940 km² | 100% |

Frequently asked questions
How deep is the Marguerite Bay?
On average about 343 m in the GEBCO grid (the middle value is 283 m). The deepest cell inside its outline is 1,594 m, at 68.70° S, 70.07° W.
How big is the Marguerite Bay?
About 22,940 km² of water inside its Natural Earth outline, counted from the grid cells that are below sea level.
How much of the Marguerite Bay would be land if sea level dropped?
With the sea 10 m lower, about 435 km² (1.9%) 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.
