How deep is each part of the Delaware Bay?
The bar splits the Delaware Bay's water by depth. Each colour is a depth band, and the shares add up to 100%.
- 0 to 200 m: 100%
- 200 to 1,000 m: 0%
- 1,000 to 4,000 m: 0%
- 4,000 to 6,000 m: 0%

The Delaware Bay if sea level dropped
The slider on the map lowers the sea in steps. This table shows how much of the Delaware Bay's water would be land at each step.
| Sea level lowered by | Becomes land | Share of its water |
|---|---|---|
| 10 m | 1,600 km² | 83.9% |
| 20 m | 1,862 km² | 97.6% |
| 50 m | 1,907 km² | 100% |
| 80 m | 1,907 km² | 100% |
| 120 m | 1,907 km² | 100% |
| 200 m | 1,907 km² | 100% |
| 500 m | 1,907 km² | 100% |
| 1,000 m | 1,907 km² | 100% |
| 2,000 m | 1,907 km² | 100% |
| 3,000 m | 1,907 km² | 100% |
| 4,000 m | 1,907 km² | 100% |
| 6,000 m | 1,907 km² | 100% |
A simple bathtub model: it lowers the sea everywhere by the same amount and does not simulate how water would really drain.

Frequently asked questions
How deep is the Delaware Bay?
On average about 6 m in the GEBCO grid (the middle value is 5 m). The deepest cell inside its outline is 45 m, at 38.85° N, 75.08° W.
How big is the Delaware Bay?
About 1,907 km² of water inside its Natural Earth outline, counted from the grid cells that are below sea level.
How much of the Delaware Bay would be land if sea level dropped?
With the sea 10 m lower, about 1,600 km² (83.9%) 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.
