Frequently asked questions
How deep is the Smith Sound?
On average about 164 m in the GEBCO grid (the middle value is 143 m). The deepest cell inside its outline is 589 m, at 52.31° N, 127.06° W.
How big is the Smith Sound?
About 1,100 km² of water inside its Natural Earth outline, counted from the grid cells that are below sea level.
How much of the Smith Sound would be land if sea level dropped?
With the sea 10 m lower, about 51 km² (4.6%) 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.
