Frequently asked questions
How deep is the Pamlico Sound?
On average about 4 m in the GEBCO grid (the middle value is 4 m). The deepest cell inside its outline is 20 m, at 34.91° N, 76.34° W.
How big is the Pamlico Sound?
About 5,225 km² of water inside its Natural Earth outline, counted from the grid cells that are below sea level.
How much of the Pamlico Sound would be land if sea level dropped?
With the sea 10 m lower, about 5,177 km² (99.1%) 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.
