The Robeson Channel if sea level dropped
The slider on the map lowers the sea in steps. This table shows how much of the Robeson Channel's water would be land at each step.
| Sea level lowered by | Becomes land | Share of its water |
|---|---|---|
| 10 m | 19 km² | 1.1% |
| 20 m | 29 km² | 1.7% |
| 50 m | 64 km² | 3.7% |
| 80 m | 93 km² | 5.4% |
| 120 m | 137 km² | 7.9% |
| 200 m | 222 km² | 12.8% |
| 500 m | 1,299 km² | 74.5% |
| 1,000 m | 1,743 km² | 100% |
| 2,000 m | 1,743 km² | 100% |
| 3,000 m | 1,743 km² | 100% |
| 4,000 m | 1,743 km² | 100% |
| 6,000 m | 1,743 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 Robeson Channel?
On average about 409 m in the GEBCO grid (the middle value is 425 m). The deepest cell inside its outline is 814 m, at 81.98° N, 62.08° W.
How big is the Robeson Channel?
About 1,743 km² of water inside its Natural Earth outline, counted from the grid cells that are below sea level.
How much of the Robeson Channel would be land if sea level dropped?
With the sea 10 m lower, about 19 km² (1.1%) 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.
