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

|---|---|---|
| 10 m | 1,829 km² | 1.6% |
| 20 m | 4,036 km² | 3.6% |
| 50 m | 12,860 km² | 11.4% |
| 80 m | 25,105 km² | 22.3% |
| 120 m | 40,059 km² | 35.6% |
| 200 m | 53,380 km² | 47.4% |
| 500 m | 88,822 km² | 78.9% |
| 1,000 m | 108,608 km² | 96.5% |

Frequently asked questions
How deep is the Aegean Sea?
On average about 306 m in the GEBCO grid (the middle value is 219 m). The deepest cell inside its outline is 1,595 m, at 40.26° N, 25.29° E.
How big is the Aegean Sea?
About 112,557 km² of water inside its Natural Earth outline, counted from the grid cells that are below sea level.
How much of the Aegean Sea would be land if sea level dropped?
With the sea 10 m lower, about 1,829 km² (1.6%) 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.
