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.

Land height

  • Land up to 500 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.

Utah Basin is an ocean basin. In the GEBCO grid it reaches 304 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 New Zealand, about 1 km from its listed point.

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

How deep is the Utah Basin?

The grid figure is 304 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 gives 442 m, which is 138 m deeper than the grid figure of 304 m. Published depths for the same feature often differ like this: they can come from one ship's sounding of one spot rather than a gridded model, or refer to a different part of a long feature. We show both, and use the grid figure in our headline numbers because every depth on this site then comes from one source.

Among the 110 ocean basins in our list it ranks 78th 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.
