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

The Persian Gulf if sea level dropped
The slider on the map lowers the sea in steps. This table shows how much of the Persian Gulf's water would be land at each step.
| Sea level lowered by | Becomes land | Share of its water |
|---|---|---|
| 10 m | 50,200 km² | 21.1% |
| 20 m | 84,598 km² | 35.6% |
| 50 m | 164,222 km² | 69.1% |
| 80 m | 225,019 km² | 94.7% |
| 120 m | 237,351 km² | 99.9% |
| 200 m | 237,542 km² | 100% |
| 500 m | 237,566 km² | 100% |
| 1,000 m | 237,566 km² | 100% |
| 2,000 m | 237,566 km² | 100% |
| 3,000 m | 237,566 km² | 100% |
| 4,000 m | 237,566 km² | 100% |

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 Persian Gulf?
On average about 35 m in the GEBCO grid (the middle value is 30 m). The deepest cell inside its outline is 323 m, at 26.43° N, 56.52° E.
How big is the Persian Gulf?
About 237,566 km² of water inside its Natural Earth outline, counted from the grid cells that are below sea level.
How much of the Persian Gulf would be land if sea level dropped?
With the sea 10 m lower, about 50,200 km² (21.1%) 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.
