The ocean is a common aquatic biome consisting predominantly of water. Oceans are the largest biome by area, covering anywhere around 25-33% of the surface area of the Overworld when factoring in all of its variants, and consist of a deep body of water with the surface at an altitude of Y=63 by default, which is counted as the "sea level" of the world.

Description

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. The seafloor is fairly hilly, featuring multiple peaks and valleys, and is mostly made up of gravel, though some clay, dirt and sand patches may generate near the peaks. Ravines 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 beaches surrounding a patch of a common biome, such as forest or plains. The seafloor is covered with seagrass and kelp, with "forests" of kelp frequently reaching close to, or even touching the water's surface. Aquatic mobs, such as cod, salmon, squid, and dolphins, frequently spawn within oceans. Shipwrecks and underwater ruins frequently generate within all oceans, more often than other structures in other biomes. Deep ocean variants can occasionally generate ocean monuments.

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. Ocean biomes are quite vast; one might not find the mainland for hundreds or even thousands of blocks. 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. Depending on the island's size, drowned are likely to be the most frequent mob encountered, followed by skeletons. See the Island Survival article for more information.

Variants

Oceans come in nine different varieties in-game, including the base ocean and eight different variants. Both editions also have an unused Deep Warm Ocean variant, while Bedrock Edition has an additional unused Legacy Frozen Ocean variant.

Deep Ocean

Deep Ocean

Data	dec: 24 hex: 18 bin: 11000
Id	deep_ocean
Type	Aquatic
Rarity	Very common
Temperature	0.5
Structures	Ocean Monuments Shipwrecks Underwater ruins
Blocks	Water Gravel Bubble column Magma Block Obsidian Seagrass Kelp

In the Deep Ocean variant, the ocean can exceed 30 blocks in-depth, making it twice as deep as the normal ocean. The ground is mainly covered with gravel. Ocean monuments generate in deep oceans, meaning guardians and elder guardians can spawn here. Dolphins, cod, salmon‌^{[Bedrock Edition only]} and squid spawn in these oceans as well. Underwater caves and ravines often generate here, forming underwater trenches. Exposed lava in these trenches occasionally turns into magma blocks, creating whirlpool bubble columns that can drag a player down.

Frozen Ocean

Frozen Ocean

Data	dec: 10 hex: A bin: 1010
Id	frozen_ocean
Type	Aquatic
Rarity	Common
Temperature	0.0 (default; varies within ocean)
Structures	Icebergs Shipwrecks Underwater ruins
Blocks	Water Ice Snow Block Packed Ice Blue Ice Gravel Sand Clay Dirt

The Frozen Ocean variant has dark purple water at the surface. Like the cold ocean, it has a gravel seabed, though the water's surface is mostly frozen. Neither seagrass nor kelp generates on the seafloor, leaving it entirely barren and reminiscent of pre-1.13 oceans. Large icebergs made of snow blocks, packed ice, and blue ice frequently generate on the surface and polar bears and strays may spawn on these icebergs. Salmon, cod‌^{[Bedrock Edition only]} and squid may spawn here as well, and are the only aquatic mobs (other than drowned) that can.

Similarly to swamps, frozen oceans have varying temperatures across their landscapes, but have a more noticeable effect in that colder patches have snowfall and ice sheets, while warmer patches have rainfall (up to a certain height, similarly to mountains) and unfrozen water. This does not apply to their deep variants, however.

In Java Edition, frozen oceans (along with their deep variants) never generate directly bordering land. They always have a 32-block-wide border of the cold ocean around them should they generate close to any land. This border is often jagged and broken.

Deep Frozen Ocean

Deep Frozen Ocean

Data	dec: 50 hex: 32 bin: 110010
Id	deep_frozen_ocean
Type	Aquatic
Rarity	Common
Temperature	0.5
Structures	Ocean Monuments Icebergs Shipwrecks Underwater ruins
Blocks	Water Snow Block Packed Ice Ice‌[Bedrock Edition only] Blue Ice Gravel Bubble column Magma Block Obsidian

Deep Frozen Ocean variants also contain ocean monuments and a deeper floor than normal oceans. In Java Edition, unlike its shallow counterpart, the surface of the water is not frozen; however, the surface is completely frozen in Bedrock Edition. Icebergs may still generate and polar bears, strays, cod‌^{[Bedrock Edition only]} and salmon may still spawn.

Cold Ocean

Cold Ocean

Data	dec: 46 hex: 2E bin: 101110
Id	cold_ocean
Type	Aquatic
Rarity	Common
Temperature	0.5
Structures	Shipwrecks Underwater ruins
Blocks	Water Gravel Dirt Sand Clay Seagrass Kelp

The Cold Ocean variant has dark indigo water at the surface. Like regular oceans and frozen oceans, its floor is made up of gravel, although there are scarce patches of dirt, sand and clay on underwater peaks. Salmon, cod, dolphins, squid and drowned are able to spawn in cold ocean biomes, alongside all the other common hostile mobs.

Deep Cold Ocean

Deep Cold Ocean

Data	dec: 49 hex: 31 bin: 110001
Id	deep_cold_ocean
Type	Aquatic
Rarity	Common
Temperature	0.5
Structures	Ocean Monuments Shipwrecks Underwater ruins
Blocks	Water Gravel Bubble column Magma Block Obsidian Seagrass Kelp

The Deep Cold Ocean variant is similar to cold ocean biomes, but twice as deep. Like other deep oceans, ocean monuments are able to generate here, which contain guardians, elder guardians, prismarine and sponges.

Lukewarm Ocean

Lukewarm Ocean

Data	dec: 45 hex: 2D bin: 101101
Id	lukewarm_ocean
Type	Aquatic
Rarity	Common
Temperature	0.5
Structures	Shipwrecks Underwater ruins
Blocks	Water Sand Dirt Clay Gravel Seagrass Kelp

The Lukewarm Ocean variant has light teal water at the surface. Its floor is made of sand with the occasional dirt, gravel and clay and it contains kelp and seagrass. Underwater ruins that generate in lukewarm and warm oceans are made of sandy materials, as opposed to the stony materials that make up ruins in the other oceans. Cod, salmon‌^{[Bedrock Edition only]}, tropical fish‌^{[Java Edition only]} and pufferfish‌^{[Java Edition only]} may spawn here, alongside the other aquatic mobs.

Deep Lukewarm Ocean

Deep Lukewarm Ocean

Data	dec: 48 hex: 30 bin: 110000
Id	deep_lukewarm_ocean
Type	Aquatic
Rarity	Common
Temperature	0.5
Structures	Ocean Monuments Shipwrecks Underwater ruins
Blocks	Water Sand Bubble column Magma Block Obsidian Seagrass Kelp

The Deep Lukewarm Ocean variant is similar to lukewarm ocean biomes but twice as deep. Since they are a deep ocean variant, they can generate ocean monuments, resulting in the spawning of guardians, elder guardians, prismarine, and sponges.

Warm Ocean

Warm Ocean

Data	dec: 44 hex: 2C bin: 101100
Id	warm_ocean
Type	Aquatic
Rarity	Common
Temperature	0.5
Structures	Coral reefs Shipwrecks Underwater ruins
Blocks	Water Sand Dirt Clay Gravel Coral Blocks Coral Coral Fans Sea Pickles Seagrass

The Warm Ocean variant has light green water at the surface. Like the lukewarm ocean, it has a floor made of sand, and like all except frozen oceans, it is populated with seagrass. Warm oceans feature large coral reefs and numerous sea pickles, though kelp does not naturally generate here. Because of the height of the coral reef, warm oceans can appear more shallow than other oceans, though the actual ocean floor is no deeper. Tropical fish and pufferfish may spawn here, like in lukewarm oceans, though cod does not spawn.

In Java Edition, similarly to frozen oceans, warm oceans never generate directly bordering land. They always have a 32-block-wide border of the lukewarm ocean around them should they generate close to any land. This border is also very jagged, like frozen oceans.

Deep Warm Ocean

Deep Warm Ocean

Data	dec: 47 hex: 2F bin: 101111
Id	deep_warm_ocean
Type	Aquatic
Rarity	N/A
Temperature	0.5
Structures	Ocean Monuments Shipwrecks Underwater ruins
Blocks	Water Sand Bubble column Magma Block Obsidian Seagrass

The Deep Warm Ocean variant is similar to warm ocean biomes, but without coral reefs nor sea pickles, and twice as deep. Since they are a deep ocean variant, they can generate ocean monuments, resulting in the spawning of guardians, elder guardians, prismarine, and sponges. This biome does not naturally generate, though it can be generated using a Customized Superflat world or the appropriate Buffet world options‌^{[Java Edition only]} or addons‌^{[Bedrock Edition only]}.

Legacy Frozen Ocean

Legacy Frozen Ocean

Data	dec: -116 hex: FFFFFFFFFFFFFF8C bin:
Id	legacy_frozen_ocean
Type	Aquatic
Rarity	N/A
Temperature	0.0
Structures	Shipwrecks Underwater ruins
Blocks	Ice Water Gravel Bubble column Magma Block Obsidian Seagrass Kelp

The Legacy Frozen Ocean variant is similar to frozen ocean biomes, but without icebergs, making it look like flatlands of ice. Polar bears and strays can spawn in here. Unlike the regular frozen ocean biome, rabbits can spawn here and have their snowy texture. Also unlike the regular frozen ocean, no monsters other than drowned, strays and skeletons can spawn here. This biome also generates kelp. This biome existed prior in Pocket Edition Alpha 0.9.0. This biome does not naturally generate, though it can be generated using a biome editor or add-ons.

Trivia

• The plains and forest biomes also generates in patches within normal deep ocean biomes, similar to how 'Hills' biomes generate within their respective base biomes.
• Although normal Deep ocean biomes can generate standalone, normal deep ocean biomes also generates in patches within normal ocean biomes, similar to how 'Hills' biomes generate within their respective base biomes.
