How deep is each part of the Norwegian Sea?
The bar splits the Norwegian Sea's water by depth. Each colour is a depth band, and the shares add up to 100%.
- 0 to 200 m: 9.9%
- 200 to 1,000 m: 26.3%
- 1,000 to 4,000 m: 63.9%
- 4,000 to 6,000 m: 0%
- below 6,000 m: 0%

The Norwegian Sea if sea level dropped
The slider on the map lowers the sea in steps. This table shows how much of the Norwegian Sea's water would be land at each step.
| Sea level lowered by | Becomes land | Share of its water |
|---|---|---|
| 10 m | 3,074 km² | 0.2% |
| 20 m | 6,669 km² | 0.4% |
| 50 m | 20,179 km² | 1.3% |
| 80 m | 36,024 km² | 2.4% |
| 120 m | 62,311 km² | 4.1% |
| 200 m | 150,342 km² | 9.8% |
| 500 m | 443,448 km² | 29% |
| 1,000 m | 551,633 km² | 36.1% |
| 2,000 m | 850,053 km² | 55.7% |
| 3,000 m | 1.3 million km² | 82.3% |
| 4,000 m | 1.5 million km² | 100% |
| 6,000 m | 1.5 million 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 Norwegian Sea?
On average about 1,684 m in the GEBCO grid (the middle value is 1,691 m). The deepest cell inside its outline is 4,057 m, at 68.61° N, 3.51° W.
How big is the Norwegian Sea?
About 1.5 million km² of water inside its Natural Earth outline, counted from the grid cells that are below sea level.
How much of the Norwegian Sea would be land if sea level dropped?
With the sea 50 m lower, about 20,179 km² (1.3%) 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.
