Minecraft Deep Ocean Finder
Every patch · freeJava 26.2 & Bedrock 1.26.30Highlight every Deep Ocean on your Minecraft seed — Java 26.2 & Bedrock 1.26.30, 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. 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 do I find a Deep Ocean on my seed?
Enter your seed and the map highlights every Deep Ocean — click any highlighted patch to read its coordinates. The finder runs the same world-generation maths Minecraft uses, so the deep basins are marked exactly on any seed and in either edition.
Why look for a Deep Ocean?
Deep Oceans are the home of ocean monuments — vast prismarine temples guarded by guardians and elder guardians, holding sponge rooms and 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.
Does the Deep Ocean finder work on Bedrock?
Yes — both editions, Minecraft 26.2 on Java and 1.26.30 on Bedrock. Deep Oceans and their monuments generate the same way on both. The map highlights every patch on your seed, free and with no sign-up.
