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 varieties. 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, going from sea level all the way down to the ocean floor, which is at a depth of roughly Y=45 for normal oceans, or 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 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 when bordering on land, while deep variants generate when away from land.

Survival in ocean biomes themselves is impractical due to 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

When in any ocean biome, unique ocean ambience play randomly. Normal overworld tracks also play, alongside “Axolotl”, “Dragon Fish”, and “Shuniji”, as the requirements for those are merely to be underwater rather than biome-determined.

History

[hide]Java Edition Classic
0.0.12a							An infinite ocean now surrounds the map.
[hide]Java Edition Infdev
20100227-1414							Added infinite worlds. Oceans generate as random parts of the terrain, similarly to mountains.
[hide]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.
[hide]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.
							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 sand or gravel floor.

			beta 1.2.20.1				Added underwater ruins.
1.17.0 Experiment Caves and Cliffs			beta 1.16.230.56				All oceans generate with a stone floor below Y=51 instead of a sand or gravel floor behind the Caves & Cliffs experimental gameplay toggle. This does not occur in the Old world type.
1.17.30 Experiment Caves and Cliffs			beta 1.17.30.23				All oceans generate with a sand or 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.
[hide]Legacy Console Edition
Xbox 360	Xbox One	PS3	PS4	PS Vita	Wii U	Switch
TU5	CU1	1.00	1.00	1.00	Patch 1	1.0.1	As part of a terrain generation overhaul, oceans have been made into their own proper biome.
TU31	CU19	1.22	1.22	1.22	Patch 3		Added ocean monuments.
TU69		1.76	1.76	1.76	Patch 38		Added shipwrecks, and underwater ruins.

Data history
