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 Kupe Abyssal Plain?

The grid figure is 4,205 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 18 abyssal plains in our list it ranks 10th by depth. The list is the named features on Wikidata with a position at sea, so it is not every abyssal plain in the world.

About abyssal plains

An abyssal plain is a vast, flat stretch of deep seabed, built up over millions of years as fine sediment settles from above.

This site lists 18 abyssal plains, 8 of them with their own indexed page. See all undersea features.
