How deep is each part of the La Pérouse Strait?
The bar splits the La Pérouse Strait'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 La Pérouse Strait if sea level dropped
The slider on the map lowers the sea in steps. This table shows how much of the La Pérouse Strait's water would be land at each step.
| Sea level lowered by | Becomes land | Share of its water |
|---|---|---|
| 10 m | 10 km² | 56.8% |
| 20 m | 17 km² | 100% |
| 50 m | 17 km² | 100% |
| 80 m | 17 km² | 100% |
| 120 m | 17 km² | 100% |
| 200 m | 17 km² | 100% |
| 500 m | 17 km² | 100% |
| 1,000 m | 17 km² | 100% |
| 2,000 m | 17 km² | 100% |
| 3,000 m | 17 km² | 100% |
| 4,000 m | 17 km² | 100% |
| 6,000 m | 17 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 La Pérouse Strait?
On average about 7 m in the GEBCO grid (the middle value is 8 m). The deepest cell inside its outline is 20 m, at 45.45° N, 141.84° E.
How big is the La Pérouse Strait?
About 17 km² of water inside its Natural Earth outline, counted from the grid cells that are below sea level.
How much of the La Pérouse Strait would be land if sea level dropped?
With the sea 10 m lower, about 10 km² (56.8%) 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.
