How deep is each part of the Beaufort Sea?
The bar splits the Beaufort Sea's water by depth. Each colour is a depth band, and the shares add up to 100%.
- 0 to 200 m: 30.6%
- 200 to 1,000 m: 18.9%
- 1,000 to 4,000 m: 50.5%
- 4,000 to 6,000 m: 0%
- below 6,000 m: 0%
Named features near the deepest point: Barrow Canyon (292 km), Canada Abyssal Plain (341 km), Northwind Ridge (486 km), Herschel Basin (505 km).
The Beaufort Sea if sea level dropped
The slider on the map lowers the sea in steps. This table shows how much of the Beaufort Sea's water would be land at each step.
| Sea level lowered by | Becomes land | Share of its water |
|---|---|---|
| 10 m | 16,625 km² | 3.9% |
| 20 m | 33,918 km² | 8.1% |
| 50 m | 84,941 km² | 20.2% |
| 80 m | 109,896 km² | 26.1% |
| 120 m | 117,587 km² | 27.9% |
| 200 m | 128,966 km² | 30.6% |
| 500 m | 188,116 km² | 44.7% |
| 1,000 m | 208,606 km² | 49.5% |
| 2,000 m | 257,110 km² | 61% |
| 3,000 m | 347,146 km² | 82.4% |
| 4,000 m | 421,277 km² | 100% |
| 6,000 m | 421,277 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 Beaufort Sea?
On average about 1,407 m in the GEBCO grid (the middle value is 1,058 m). The deepest cell inside its outline is 3,731 m, at 72.41° N, 149.53° W.
How big is the Beaufort Sea?
About 421,277 km² of water inside its Natural Earth outline, counted from the grid cells that are below sea level.
How much of the Beaufort Sea would be land if sea level dropped?
With the sea 10 m lower, about 16,625 km² (3.9%) 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.
