The Labrador Sea if sea level dropped
The slider on the map lowers the sea in steps. This table shows how much of the Labrador Sea's water would be land at each step.

|---|---|---|
| 10 m | 4,549 km² | 0.5% |
| 20 m | 8,296 km² | 1% |
| 50 m | 23,492 km² | 2.7% |
| 80 m | 34,997 km² | 4% |
| 120 m | 51,038 km² | 5.9% |
| 200 m | 146,042 km² | 16.8% |
| 500 m | 327,285 km² | 37.6% |
| 1,000 m | 346,850 km² | 39.8% |

Frequently asked questions
How deep is the Labrador Sea?
On average about 1,948 m in the GEBCO grid (the middle value is 2,518 m). The deepest cell inside its outline is 4,124 m, at 55.85° N, 48.08° W.
How big is the Labrador Sea?
About 870,545 km² of water inside its Natural Earth outline, counted from the grid cells that are below sea level.
How much of the Labrador Sea would be land if sea level dropped?
With the sea 50 m lower, about 23,492 km² (2.7%) 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.
