How deep is each part of the Sargasso Sea?
The bar splits the Sargasso Sea's water by depth. Each colour is a depth band, and the shares add up to 100%.
- 0 to 200 m: 0%
- 200 to 1,000 m: 0%
- 1,000 to 4,000 m: 0.5%
- 4,000 to 6,000 m: 93.6%
- below 6,000 m: 5.9%

|---|---|---|
| 10 m | 87 km² | under 0.1% |
| 20 m | 751 km² | under 0.1% |
| 50 m | 923 km² | under 0.1% |
| 80 m | 972 km² | under 0.1% |
| 120 m | 1,030 km² | under 0.1% |
| 200 m | 1,120 km² | under 0.1% |
| 500 m | 1,327 km² | under 0.1% |
| 1,000 m | 1,649 km² | under 0.1% |
| 2,000 m | 3,024 km² | 0.1% |
| 3,000 m | 6,729 km² | 0.2% |
| 4,000 m | 15,354 km² | 0.5% |
| 6,000 m | 2.8 million km² | 94.1% |
A simple bathtub model: it lowers the sea everywhere by the same amount and does not simulate how water would really drain.

Frequently asked questions
How deep is the Sargasso Sea?
On average about 5,394 m in the GEBCO grid (the middle value is 5,445 m). The deepest cell inside its outline is 7,761 m, at 23.41° N, 56.75° W.
How big is the Sargasso Sea?
About 3 million km² of water inside its Natural Earth outline, counted from the grid cells that are below sea level.
How much of the Sargasso Sea would be land if sea level dropped?
With the sea 6,000 m lower, about 2.8 million km² (94.1%) of its water would be land. At 6,000 m lower, 94.1% would be. This is a simple bathtub model that lowers the sea evenly everywhere.
