Sea level in metres below today’s. A simple bathtub model: it lowers the sea everywhere by the same amount and does not simulate how the water would really drain.

Key

Sea depth

  • Deeper than 6,000 m
  • 4,000 to 6,000 m
  • 2,000 to 4,000 m
  • 1,000 to 2,000 m
  • 200 to 1,000 m
  • Shallower than 200 m (the continental shelf)

Land height

  • Land up to 500 m
  • 500 to 2,000 m
  • Above 2,000 m

How to read the map. Darker blue is deeper water. Tap anywhere to see how deep the sea is there, or how high the land is, and the nearest named undersea feature. Depths come from the GEBCO_2026 grid, which in most of the deep ocean is predicted from satellite measurements of the sea surface rather than surveyed by ship, and the map’s tiles are coarser than the grid, so narrow trenches read shallower on the map than their true depth. Not for navigation.

How deep is each part of the Java Sea?

The bar splits the Java Sea's water by depth. Each colour is a depth band, and the shares add up to 100%.

  • 0 to 200 m: 90%
  • 200 to 1,000 m: 9%
  • 1,000 to 4,000 m: 0.9%
  • 4,000 to 6,000 m: 0%
  • below 6,000 m: 0%

Named features near the deepest point: Batu Buntunga (108 km), Yersey (720 km), Nieuwerkerk (760 km), Sunda Trench (1,084 km).

Frequently asked questions

How deep is the Java Sea?

On average about 91 m in the GEBCO grid (the middle value is 43 m). The deepest cell inside its outline is 1,885 m, at 4.77° S, 118.06° E.

How big is the Java Sea?

About 545,163 km² of water inside its Natural Earth outline, counted from the grid cells that are below sea level.

How much of the Java Sea would be land if sea level dropped?

With the sea 10 m lower, about 48,671 km² (8.9%) 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.

Data: depths from the GEBCO_2026 grid, statistics worked out inside the Natural Earth outline of the sea. See data sources and licences. The GEBCO Grid should NOT be used for navigation or for any other purpose involving safety at sea.
