Frequently asked questions
How deep is the Bransfield Strait?
On average about 608 m in the GEBCO grid (the middle value is 449 m). The deepest cell inside its outline is 2,798 m, at 61.78° S, 55.46° W.
How big is the Bransfield Strait?
About 71,790 km² of water inside its Natural Earth outline, counted from the grid cells that are below sea level.
How much of the Bransfield Strait would be land if sea level dropped?
With the sea 20 m lower, about 1,069 km² (1.5%) 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.
