| 10 m | 4,474 km² | 90.4% |
| 20 m | 4,926 km² | 99.5% |
| 50 m | 4,951 km² | 100% |
| 80 m | 4,951 km² | 100% |
| 120 m | 4,951 km² | 100% |
| 200 m | 4,951 km² | 100% |

Frequently asked questions
How deep is the Tatar Strait?
On average about 5 m in the GEBCO grid (the middle value is 4 m). The deepest cell inside its outline is 47 m, at 53.04° N, 140.93° E.
How big is the Tatar Strait?
About 4,951 km² of water inside its Natural Earth outline, counted from the grid cells that are below sea level.
How much of the Tatar Strait would be land if sea level dropped?
With the sea 10 m lower, about 4,474 km² (90.4%) 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.
