The Ligurian Sea if sea level dropped
The slider on the map lowers the sea in steps. This table shows how much of the Ligurian Sea's water would be land at each step.
| Sea level lowered by | Becomes land | Share of its water |
|---|---|---|
| 10 m | 30 km² | 0.2% |
| 20 m | 67 km² | 0.5% |
| 50 m | 251 km² | 1.9% |
| 80 m | 520 km² | 4% |
| 120 m | 860 km² | 6.6% |
| 200 m | 1,214 km² | 9.3% |
| 500 m | 2,676 km² | 20.6% |
| 1,000 m | 6,225 km² | 47.8% |
| 2,000 m | 10,424 km² | 80.1% |
| 3,000 m | 13,020 km² | 100% |
| 4,000 m | 13,020 km² | 100% |
| 6,000 m | 13,020 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 Ligurian Sea?
On average about 1,194 m in the GEBCO grid (the middle value is 1,048 m). The deepest cell inside its outline is 2,620 m, at 43.75° N, 8.58° E.
How big is the Ligurian Sea?
About 13,020 km² of water inside its Natural Earth outline, counted from the grid cells that are below sea level.
How much of the Ligurian Sea would be land if sea level dropped?
With the sea 50 m lower, about 251 km² (1.9%) 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.
