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.

Frequently asked questions

How deep is the Richard Collinson Inlet?

On average about 17 m in the GEBCO grid (the middle value is 12 m). The deepest cell inside its outline is 80 m, at 73.11° N, 113.70° W.

How big is the Richard Collinson Inlet?

About 998 km² of water inside its Natural Earth outline, counted from the grid cells that are below sea level.

How much of the Richard Collinson Inlet would be land if sea level dropped?

With the sea 10 m lower, about 424 km² (42.4%) 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 bay. See data sources and licences. The GEBCO Grid should NOT be used for navigation or for any other purpose involving safety at sea.
