The Hudson Strait if sea level dropped
The slider on the map lowers the sea in steps. This table shows how much of the Hudson Strait's water would be land at each step.

|---|---|---|
| 10 m | 2,932 km² | 1.9% |
| 20 m | 5,140 km² | 3.4% |
| 50 m | 11,857 km² | 7.8% |
| 80 m | 18,388 km² | 12.1% |
| 120 m | 29,389 km² | 19.3% |
| 200 m | 58,994 km² | 38.7% |
| 500 m | 146,384 km² | 95.9% |
| 1,000 m | 152,569 km² | 100% |

Frequently asked questions
How deep is the Hudson Strait?
On average about 241 m in the GEBCO grid (the middle value is 232 m). The deepest cell inside its outline is 1,133 m, at 60.91° N, 65.18° W.
How big is the Hudson Strait?
About 152,569 km² of water inside its Natural Earth outline, counted from the grid cells that are below sea level.
How much of the Hudson Strait would be land if sea level dropped?
With the sea 10 m lower, about 2,932 km² (1.9%) 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.
