Minecraft Deep Ocean Finder
Highlight every Deep Ocean patch on your Minecraft seed — Java 26.3 & Bedrock 1.26.62, any seed, free, no sign-up.
Quick answer: Deep Oceans are the deep central basins of the open sea, deep enough for towering ocean monuments to generate, guarded by guardians and rich in prismarine and sponges. Half of worlds have one within 900 blocks of the world centre. This finder highlights every Deep Ocean patch on your seed, free, Java & Bedrock.
Where do Deep Oceans generate?
Deep Oceans generate on the Overworld surface in the deepest parts of the open sea, where the water column is far taller than in a normal ocean. The extra depth is what lets ocean monuments generate here, and the temperate Deep Ocean sits between the deep lukewarm and deep cold seas.
How far away is the nearest Deep Ocean?
Usually within 1,000 blocks. Across 200 random worlds, half had a Deep Ocean within 900 blocks of the world centre (0, 0), and 9 in 10 had one within 1,750. Enter your seed above and click any highlighted patch to read its coordinates. The deep lukewarm, cold and frozen oceans are separate biomes with their own finders, and monuments generate in all four.
| How close | Java and Bedrock |

| Half of worlds have one within | 900 blocks |
| 9 worlds in 10 have one within | 1,750 blocks |
| Worlds with one within 1,000 blocks | 6 in 10 |
Measured with this finder on 200 random worlds, from the centre of the world (0, 0). A seed puts its biomes in the same places on Java and Bedrock, so one column covers both. Distances are rounded.
Why look for a Deep Ocean?
Deep Oceans are one of the four deep ocean biomes where ocean monuments generate — vast prismarine temples guarded by guardians and three elder guardians, holding sponge rooms and eight hidden blocks of gold. They are the best place to gather prismarine, sea lanterns and sponges, while the deep water also hides ravines, magma blocks and the occasional shipwreck.
