The ocean is an aquatic biome consisting of water. All oceans together are the largest biomes by area, covering anywhere around 28–29% of the surface area of the Overworld when factoring in all of its variants. They are deep bodies of water with the surface at an altitude of Y=63 by default, which is counted as the “sea level” of the world.

Description

The separate colors of each ocean variant in *Java Edition*.

Oceans are vast expanses of water from sea level to the ocean floor, which is at a depth of roughly Y=45 for normal oceans and Y=30 for deep variants. The seafloor is fairly hilly, featuring multiple peaks and valleys, and is mostly covered by a one-block layer of gravel or sand, though some clay, dirt, gravel, and sand patches may generate near the peaks. Canyons can occasionally generate on the ocean floor, forming underwater trenches. Some seafloor peaks may reach high enough to form islands on the surface of the ocean; these islands are typically small and may have very sparse vegetation with very little grass and few oak trees. The seafloor is often covered with seagrass and kelp, with “forests” of kelp frequently reaching close to or even touching the water's surface. Fish, squid, and dolphins frequently spawn within oceans. Shipwrecks and ocean ruins generate within all oceans, while deep ocean variants can occasionally generate ocean monuments. The regular ocean variant mainly generates adjacent to land, while deep variants generate farther from land.

Survival in ocean biomes is impractical because of all the water. A player who camps on an island in the ocean faces a rather difficult situation. This means that whatever resources found on an island might be all the player has if the player is unwilling or unable to venture out. See the island survival article for more information.

Sounds

In any ocean biome, unique ocean ambience plays randomly. Normal overworld tracks also play, alongside “Axolotl”, “Dragon Fish”, and “Shuniji”, as the requirements for those are merely to be underwater, regardless of biome.

History

Java Edition

Java Edition Classic
0.0.12a		An infinite ocean now surrounds the map.
Java Edition Infdev
20100227-1414		Added infinite worlds. Oceans generate as random parts of the terrain, similarly to mountains.
Java Edition Beta
1.8	Pre-release	As part of a terrain generation overhaul, oceans have been made into their own proper biome. Previously, oceans were not considered their own biome.
		The ocean level has been decreased by one block (64 to 63).
		Oceans have been made much larger and take up most of the map and their floors were made of a mix of clay, dirt and sand.
Java Edition
1.7.2	13w36a	Oceans have been made much smaller. In addition, oceans now only have gravel as the ocean floor. In contrast, old oceans had their floors made out of dirt, sand and clay.
1.7.2	13w36a	Ocean is now required for the new "Adventuring Time" achievement.
1.8	14w25a	Added ocean monuments, which generate in oceans.
1.13	18w09a	Added underwater ruin structures, which generate in oceans.
	18w10a	Ocean is no longer required for the "Adventuring Time" advancement.
	18w11a	Added shipwrecks, which generate in oceans.
1.16	20w06a	Underwater ruins and shipwrecks are now rarer.
1.17	21w06a	Ocean biomes generate with a stone floor below Y=50 instead of a gravel floor.^[1]
1.17	21w15a	Oceans generate with a gravel floor once again.
1.18	21w44a	Ocean is once again required for the "Adventuring Time" advancement.

Bedrock Edition

Pocket Edition Alpha
v0.1.0		Oceans generate as random parts of the terrain, similarly to mountains. In snowy biomes, ice generates on the surface.
v0.9.0	build 1	Ported all the biomes from Java Edition 1.7.2 and overhauled the terrain generation. As part of this, oceans have been made into their own proper biome.
v0.16.0	build 1	Added ocean monuments with guardians and elder guardians.
Bedrock Edition
1.4.0	beta 1.2.14.2	Added shipwrecks.
1.4.0	beta 1.2.20.1	Added underwater ruins.
1.17.0 Experiment Caves and Cliffs	beta 1.16.230.56	Oceans generate with a stone floor below Y=51 instead of a gravel floor behind the Caves & Cliffs experimental gameplay toggle.^[2] This does not occur in the Old world type.
1.17.30 Experiment Caves and Cliffs	beta 1.17.30.23	Oceans generate with a gravel floor once again.
1.21.60	Preview 1.21.60.23	Kelp now generates more frequently and in denser patches, except for in frozen ocean biomes.
