|---|---|---|
| 10 m | 1,670 km² | 94.3% |
| 20 m | 1,768 km² | 99.8% |
| 50 m | 1,772 km² | 100% |
| 80 m | 1,772 km² | 100% |
| 120 m | 1,772 km² | 100% |
| 200 m | 1,772 km² | 100% |
| 500 m | 1,772 km² | 100% |
| 1,000 m | 1,772 km² | 100% |

Frequently asked questions
How deep is the Boca Grande?
On average about 3 m in the GEBCO grid (the middle value is 2 m). The deepest cell inside its outline is 25 m, at 8.77° N, 60.71° W.
How big is the Boca Grande?
About 1,772 km² of water inside its Natural Earth outline, counted from the grid cells that are below sea level.
How much of the Boca Grande would be land if sea level dropped?
With the sea 10 m lower, about 1,670 km² (94.3%) 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.
