How do I find an Ocean Monument in the Deep Ocean?

Ocean Monuments are large structures made of prismarine. They show up as dark structures on the ocean floor. Use the /locatebiome command (Java) to find the biome, then explore to locate the monument. Monuments can be far apart so it might take a while to find one.

What should I bring before exploring the Deep Ocean?

Bring a Potion of Water Breathing so you can breathe underwater. Healing potions are essential since Guardians deal heavy damage. A sword, pickaxe, and building blocks help too. Armor enchanted with Protection and Respiration is useful if you have it.

How do I defeat Guardians without taking damage?

Guardians can't shoot through solid blocks, so place blocks between you and them to block their laser. Mine the monument carefully, using the structure itself for cover. A bow and arrows work well for hitting them from a distance. Potions of Strength help deal more damage.

What loot can I get from Ocean Monuments?

Ocean Monuments contain wet sponges, gold blocks, and prismarine variants. The sponges are useful for drying out rooms underwater. There are also chests with enchanted books and other valuables if you search thoroughly.

How deep does the Deep Ocean go?

The Deep Ocean is deeper than regular oceans, dropping to Y-level around 33 or lower depending on the terrain. You'll hit sand, then stone, then ores as you dig deeper. The ocean floor itself is usually 20+ blocks below the surface.

Deep Ocean Biome Guide | Minecraft 1.16+

The Deep Ocean biome is one of the most dangerous places you can explore in Minecraft. It’s a massive water world that drops deep, packed with hostile mobs and underwater structures. If you want loot and a real challenge, this is where you go.

What You’ll Find

The Deep Ocean is basically endless water that gets dark fast. You spawn at sea level and the ocean floor is way down there. Most players skip these biomes because they’re hard to navigate and the mobs will kill you quick if you’re not ready. But there’s good treasure if you’re brave enough to go looking for it.

Vegetation and Materials

Water plants grow everywhere. You’ll see seagrass and kelp on the ocean floor and floating up through the water. These don’t give you much but they’re everywhere so you can farm them if you need to.

The ocean floor is covered in sand, and you’ll find prismarine, dark prismarine, and sea lanterns scattered around. These blocks look cool and are used for underwater builds. Dig deeper and you hit the standard Minecraft stuff like stone, coal ore, iron ore, gold ore, diamond ore, and redstone ore.

Mobs

Squids, glow squids, and cod swim around in the water. None of them are dangerous. The real threat comes from Guardians and Elder Guardians. These mobs guard Ocean Monuments and they will wreck you. Their laser attacks hit hard and they can see through walls. Bring a Potion of Water Breathing or you’ll drown before you even get close to fighting.

Pro tip: Always bring healing potions and a Potion of Water Breathing when exploring the Deep Ocean.

Ocean Monuments

Ocean Monuments are huge underwater structures made of prismarine blocks. They’re lit up with sea lanterns so you can see them from a distance. The whole thing is held up by massive pillars made of prismarine bricks.

Two types of mobs guard these structures: Guardians and Elder Guardians. Guardians have a laser attack that shoots from their eye. Elder Guardians are tougher and hit harder. Both will attack if you get close. You’ll hear an eerie sound when they target you, which is basically a warning to get out or prepare for a fight.

If you manage to raid an Ocean Monument, you get sponge blocks, gold, and other valuables. It’s worth the effort if you’re prepared.

Finding a Deep Ocean Biome

Just explore. If you travel far enough from spawn, you’ll find oceans. The Deep Ocean is the darker, deeper version. You can also use the /locatebiome command if you want to find one fast. In Java Edition, type: /locatebiome minecraft:deep_ocean

Biome ID (Java Edition)

Minecraft ID: minecraft:deep_ocean

Versions: 1.16 – 1.19.2

This ID is used in commands like /locatebiome and /setbiome if you’re in creative mode.

Seeds for Deep Ocean Spawns

If you want to spawn directly in a Deep Ocean biome instead of searching, use a specific seed. Check the world seed list for seeds that start you in this biome. Then generate a new world with that seed and you’ll spawn in or near a Deep Ocean.
