Frequently asked questions
How deep is the Laccadive Sea?
On average about 1,956 m in the GEBCO grid (the middle value is 2,181 m). The deepest cell inside its outline is 4,313 m, at 4.66° N, 78.63° E.
How big is the Laccadive Sea?
About 816,957 km² of water inside its Natural Earth outline, counted from the grid cells that are below sea level.
How much of the Laccadive Sea would be land if sea level dropped?
With the sea 10 m lower, about 8,869 km² (1.1%) 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.
