How deep is each part of the Arabian Sea?
The bar splits the Arabian Sea's water by depth. Each colour is a depth band, and the shares add up to 100%.
- 0 to 200 m: 6.9%
- 200 to 1,000 m: 2%
- 1,000 to 4,000 m: 56%
- 4,000 to 6,000 m: 35.1%
- below 6,000 m: 0%

The Arabian Sea if sea level dropped
The slider on the map lowers the sea in steps. This table shows how much of the Arabian Sea's water would be land at each step.

|---|---|---|
| 10 m | 10,449 km² | 0.3% |
| 20 m | 28,471 km² | 0.7% |
| 50 m | 113,244 km² | 2.7% |
| 80 m | 191,354 km² | 4.6% |
| 120 m | 262,748 km² | 6.3% |
| 200 m | 286,575 km² | 6.9% |
| 500 m | 320,769 km² | 7.7% |

Frequently asked questions
How deep is the Arabian Sea?
On average about 3,313 m in the GEBCO grid (the middle value is 3,684 m). The deepest cell inside its outline is 9,536 m, at 11.48° N, 65.04° E.
How big is the Arabian Sea?
About 4.1 million km² of water inside its Natural Earth outline, counted from the grid cells that are below sea level.
How much of the Arabian Sea would be land if sea level dropped?
With the sea 50 m lower, about 113,244 km² (2.7%) 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.
