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 Bohol Sea?

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

  • 0 to 200 m: 16.6%
  • 200 to 1,000 m: 37.1%
  • 1,000 to 4,000 m: 46.3%
  • 4,000 to 6,000 m: 0%
  • below 6,000 m: 0%

Named features near the deepest point: Philippine Trench (205 km), Galathea Depth (369 km), Sulu Trench (459 km), Sangihe Trench (598 km).

Frequently asked questions

How deep is the Bohol Sea?

On average about 913 m in the GEBCO grid (the middle value is 840 m). The deepest cell inside its outline is 2,084 m, at 9.37° N, 124.94° E.

How big is the Bohol Sea?

About 37,319 km² of water inside its Natural Earth outline, counted from the grid cells that are below sea level.

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

With the sea 10 m lower, about 1,397 km² (3.7%) 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.

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.
