Deep Ocean Biome in Minecraft: Where It Is and What's There
A deep ocean is an ocean with a floor about twice as deep as normal, usually around Y=30. It is where ocean monuments generate, so guardians and elder guardians live there. Otherwise it is much like a regular ocean.
Where does the deep ocean generate?
Deep oceans form further from land than normal oceans, so they cannot border land biomes, except mushroom fields. They sit at moderate temperatures, with deep lukewarm and deep cold versions on either side.
What is in a deep ocean?
- A floor around Y=30, twice as deep as a normal ocean
- More tall seagrass than shallow oceans
- Very few islands
- Ocean monuments
Mobs and structures
Guardians and elder guardians spawn at ocean monuments, along with normal ocean fish and mobs. Drowned spawn as they do in other oceans.
How do you find one?
The fastest way to find one in a world with cheats is /locate biome minecraft:deep_ocean, which works on Java and Bedrock (Bedrock uses its own IDs for some biomes, so let tab-complete fill it in). The F3 screen on Java shows the biome you stand in. The search covers a large area but can miss very narrow strips of a biome.
How biomes are placed
Overworld biomes are placed by a few hidden noise values: temperature, humidity, continentalness (how far inland), erosion (how flat) and weirdness. That is why the same neighbours keep showing up together, and why a biome you want is usually found next to its usual partners. Biomes look and work almost the same on Java and Bedrock, with small differences in mobs and structures noted on this page. See all biomes and ocean monuments.
Tip
Bring Respiration, Depth Strider and potions of water breathing before you raid an ocean monument.
Does ArtemisPvP have its own worlds?
