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 East Siberian Sea?

The bar splits the East Siberian Sea'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%
  • below 6,000 m: 0%

Named features near the deepest point: Amerasian Basin (402 km), Lomonosov Ridge (570 km), Mendeleev Ridge (625 km), Chukchi Abyssal Plain (766 km).

Frequently asked questions

How deep is the East Siberian Sea?

On average about 26 m in the GEBCO grid (the middle value is 25 m). The deepest cell inside its outline is 69 m, at 77.46° N, 155.96° E.

How big is the East Siberian Sea?

About 602,561 km² of water inside its Natural Earth outline, counted from the grid cells that are below sea level.

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

With the sea 10 m lower, about 70,430 km² (11.7%) 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.
