Frequently asked questions
How deep is the East Korea Bay?
On average about 110 m in the GEBCO grid (the middle value is 51 m). The deepest cell inside its outline is 1,083 m, at 39.34° N, 128.30° E.
How big is the East Korea Bay?
About 7,415 km² of water inside its Natural Earth outline, counted from the grid cells that are below sea level.
How much of the East Korea Bay would be land if sea level dropped?
With the sea 10 m lower, about 104 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.
