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.

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.

Larsen Basin is an ocean basin. In the GEBCO grid it reaches 524 m below sea level. That figure is the depth in the grid at its listed centre point, so a typical depth for the feature, not its deepest or shallowest point. The nearest country in our list is Antarctica, about 88 km from its listed point.

Open the main map at its listed point and tap anywhere to read the depth.

How deep is the Larsen Basin?

The grid figure is 524 m. We measured it as the depth in the grid at its listed centre point, so a typical depth for the feature, not its deepest or shallowest point. 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 has no depth figure for this feature, so the grid is our only source for it.

Among the 110 ocean basins in our list it ranks 65th by depth. The list is the named features on Wikidata with a position at sea, so it is not every ocean basin in the world.

About ocean basins

An ocean basin is a large bowl of deep seabed bounded by ridges, rises or continental slopes.

This site lists 110 ocean basins, 32 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.
