| 20 m | 569 km² | 1.4% |
| 50 m | 1,103 km² | 2.8% |
| 80 m | 1,579 km² | 4% |
| 120 m | 2,154 km² | 5.4% |
| 200 m | 3,218 km² | 8.1% |
| 500 m | 38,112 km² | 96.2% |
| 1,000 m | 39,627 km² | 100% |

Frequently asked questions
How deep is the M'Clure Strait?
On average about 399 m in the GEBCO grid (the middle value is 425 m). The deepest cell inside its outline is 902 m, at 74.39° N, 119.73° W.
How big is the M'Clure Strait?
About 39,627 km² of water inside its Natural Earth outline, counted from the grid cells that are below sea level.
How much of the M'Clure Strait would be land if sea level dropped?
With the sea 20 m lower, about 569 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.
