The Uchiura Bay if sea level dropped
The slider on the map lowers the sea in steps. This table shows how much of the Uchiura Bay's water would be land at each step.
| Sea level lowered by | Becomes land | Share of its water |
|---|---|---|
| 10 m | 117 km² | 0.5% |
| 20 m | 502 km² | 2% |
| 50 m | 2,150 km² | 8.4% |
| 80 m | 5,092 km² | 19.9% |
| 120 m | 7,696 km² | 30% |
| 200 m | 9,112 km² | 35.5% |
| 500 m | 12,955 km² | 50.5% |
| 1,000 m | 20,285 km² | 79.1% |
| 2,000 m | 25,646 km² | 100% |
| 3,000 m | 25,646 km² | 100% |
| 4,000 m | 25,646 km² | 100% |

Frequently asked questions
How deep is the Uchiura Bay?
On average about 543 m in the GEBCO grid (the middle value is 488 m). The deepest cell inside its outline is 1,725 m, at 41.47° N, 142.06° E.
How big is the Uchiura Bay?
About 25,646 km² of water inside its Natural Earth outline, counted from the grid cells that are below sea level.
How much of the Uchiura Bay would be land if sea level dropped?
With the sea 20 m lower, about 502 km² (2%) 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.
