How deep is each part of the Murchison Sound?
The bar splits the Murchison Sound's water by depth. Each colour is a depth band, and the shares add up to 100%.
- 0 to 200 m: 55.1%
- 200 to 1,000 m: 44.9%
- 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: Baffin Basin (622 km), Barrow Basin (637 km), Grinnell Ridge (694 km), Eurasian Basin (750 km).
The Murchison Sound if sea level dropped
The slider on the map lowers the sea in steps. This table shows how much of the Murchison Sound's water would be land at each step.
| Sea level lowered by | Becomes land | Share of its water |
|---|---|---|
| 10 m | 75 km² | 1.4% |
| 20 m | 155 km² | 2.9% |
| 50 m | 668 km² | 12.5% |
| 80 m | 1,646 km² | 30.9% |
| 120 m | 2,467 km² | 46.3% |
| 200 m | 2,931 km² | 55.1% |
| 500 m | 3,566 km² | 67% |
| 1,000 m | 5,322 km² | 100% |
| 2,000 m | 5,322 km² | 100% |
| 3,000 m | 5,322 km² | 100% |
| 4,000 m | 5,322 km² | 100% |
| 6,000 m | 5,322 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 Murchison Sound?
On average about 340 m in the GEBCO grid (the middle value is 144 m). The deepest cell inside its outline is 988 m, at 77.22° N, 71.26° W.
How big is the Murchison Sound?
About 5,322 km² of water inside its Natural Earth outline, counted from the grid cells that are below sea level.
How much of the Murchison Sound would be land if sea level dropped?
With the sea 10 m lower, about 75 km² (1.4%) 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.
