How deep is each part of the Kattegat?
The bar splits the Kattegat'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 Kattegat if sea level dropped
The slider on the map lowers the sea in steps. This table shows how much of the Kattegat's water would be land at each step.

|---|---|---|
| 10 m | 4,480 km² | 19.5% |
| 20 m | 10,475 km² | 45.6% |
| 50 m | 20,185 km² | 87.8% |
| 80 m | 22,192 km² | 96.5% |
| 120 m | 22,722 km² | 98.8% |
| 200 m | 22,996 km² | 100% |
| 500 m | 22,996 km² | 100% |
| 1,000 m | 22,996 km² | 100% |

Frequently asked questions
How deep is the Kattegat?
On average about 27 m in the GEBCO grid (the middle value is 22 m). The deepest cell inside its outline is 195 m, at 58.00° N, 10.85° E.
How big is the Kattegat?
About 22,996 km² of water inside its Natural Earth outline, counted from the grid cells that are below sea level.
How much of the Kattegat would be land if sea level dropped?
With the sea 10 m lower, about 4,480 km² (19.5%) 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.
