| 10 m | 888 km² | 3.4% |
| 20 m | 3,416 km² | 13.1% |
| 50 m | 10,626 km² | 40.6% |
| 80 m | 13,766 km² | 52.7% |
| 120 m | 18,052 km² | 69% |
| 200 m | 22,777 km² | 87.1% |
| 500 m | 26,129 km² | 99.9% |
| 1,000 m | 26,145 km² | 100% |

Frequently asked questions
How deep is the Hecate Strait?
On average about 102 m in the GEBCO grid (the middle value is 73 m). The deepest cell inside its outline is 665 m, at 54.66° N, 130.72° W.
How big is the Hecate Strait?
About 26,145 km² of water inside its Natural Earth outline, counted from the grid cells that are below sea level.
How much of the Hecate Strait would be land if sea level dropped?
With the sea 10 m lower, about 888 km² (3.4%) 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.
