Frequently asked questions
How deep is the Kotzebue Sound?
On average about 10 m in the GEBCO grid (the middle value is 10 m). The deepest cell inside its outline is 28 m, at 66.81° N, 163.93° W.
How big is the Kotzebue Sound?
About 10,348 km² of water inside its Natural Earth outline, counted from the grid cells that are below sea level.
How much of the Kotzebue Sound would be land if sea level dropped?
With the sea 10 m lower, about 5,152 km² (49.8%) 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.
