How deep is each part of the Shark Bay?
The bar splits the Shark Bay'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%
Named features near the deepest point: Wallaby Plateau (511 km), Exmouth Plateau (550 km), Perth Canyon (802 km), Zenith Plateau (942 km).
The Shark Bay if sea level dropped
The slider on the map lowers the sea in steps. This table shows how much of the Shark Bay's water would be land at each step.
| Sea level lowered by | Becomes land | Share of its water |
|---|---|---|
| 10 m | 4,169 km² | 58.9% |
| 20 m | 6,879 km² | 97.2% |
| 50 m | 7,075 km² | 100% |
| 80 m | 7,075 km² | 100% |
| 120 m | 7,075 km² | 100% |
| 200 m | 7,075 km² | 100% |
| 500 m | 7,075 km² | 100% |
| 1,000 m | 7,075 km² | 100% |
| 2,000 m | 7,075 km² | 100% |
| 3,000 m | 7,075 km² | 100% |
| 4,000 m | 7,075 km² | 100% |
| 6,000 m | 7,075 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 Shark Bay?
On average about 9 m in the GEBCO grid (the middle value is 8 m). The deepest cell inside its outline is 25 m, at 24.94° S, 113.40° E.
How big is the Shark Bay?
About 7,075 km² of water inside its Natural Earth outline, counted from the grid cells that are below sea level.
How much of the Shark Bay would be land if sea level dropped?
With the sea 10 m lower, about 4,169 km² (58.9%) 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.
