|---|---|---|
| 10 m | 65,860 km² | 2.3% |
| 20 m | 130,161 km² | 4.6% |
| 50 m | 265,055 km² | 9.4% |
| 80 m | 310,125 km² | 11% |
| 120 m | 333,448 km² | 11.8% |
| 200 m | 361,256 km² | 12.8% |
| 500 m | 450,690 km² | 16% |

Frequently asked questions
How deep is the Caribbean Sea?
On average about 2,547 m in the GEBCO grid (the middle value is 2,704 m). The deepest cell inside its outline is 8,293 m, at 18.23° N, 64.72° W.
How big is the Caribbean Sea?
About 2.8 million km² of water inside its Natural Earth outline, counted from the grid cells that are below sea level.
How much of the Caribbean Sea would be land if sea level dropped?
With the sea 10 m lower, about 65,860 km² (2.3%) of its water would be land. At 6,000 m lower, 99.7% would be. This is a simple bathtub model that lowers the sea evenly everywhere.
