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.

  • 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 the Gotland Deep?

The grid figure is 250 m. We measured it as the deepest cell in the grid within 20 km of its listed point. The cell is at 57.31° N, 20.09° E. The GEBCO_2026 grid has a value every 15 arc-seconds, about 460 m at the equator, so a very narrow feature can be a little deeper or shallower in reality than any grid cell shows.

Wikidata, the open database this feature's name comes from, gives a depth of 249 m. That is within 1 m of the grid figure.

Among the 24 deeps in our list it ranks 19th by depth. The list is the named features on Wikidata with a position at sea, so it is not every deep in the world.

About deeps

A deep is the deepest part of a trench or basin: a small area, often only a few kilometres across, that gets its own name.

This site lists 24 deeps, 13 of them with their own indexed page. See all undersea features.

Nearby undersea features

Distances are between listed points. A long feature such as a trench or ridge has a single listed point on Wikidata.
