Oceans
Oceans are now 1.13's oceans: warm, lukewarm, cold, and frozen. Coral reefs grow in the warm ones. Frozen oceans carry icebergs and sea ice, with polar bears walking on top. Kelp forests and seagrass cover the floor nearly everywhere else.
Water takes its color from the biome, and daylight now reaches the sea floor. Underwater caves and ravines cut through the bottom.
A new world matches 1.13 seed for seed, so a seed map set to 1.13 shows your biomes and structures.

Sea life
Cod, salmon, pufferfish and tropical fish swim in schools. Scoop one up in a water bucket and carry it home. Tropical fish come in 2,700 looks.
Turtles nest on the beach they hatched on. Feed two of them seagrass and one lays eggs in the sand. Zombies will try to stomp the eggs. A baby drops a scute when it grows up, and five scutes make a turtle shell helmet.

Dolphins leap out of the water, toss dropped items around and chase your boat. Swim beside one for extra speed. Feed one raw fish and it leads you to a shipwreck or a ruin.
The drowned and phantoms
Drowned walk the sea floor and come ashore at night. Some carry a trident, and that is the only way to get one. A zombie left under water turns into a drowned.
The trident stabs and throws. It takes Loyalty, Riptide, Impaling and Channeling.

Skip three nights of sleep and phantoms come for you. Their membrane repairs elytra and brews Slow Falling.

Shipwrecks, ruins and treasure
Shipwrecks lie on the sea floor and on beaches. Ocean ruins hold loot chests and drowned. Either can give you a buried treasure map, and the chest under the red X holds a heart of the sea.
Eight nautilus shells around a heart of the sea make a conduit. Frame it in prismarine under water and it gives you air, night vision and faster mining. With a full frame it attacks hostile mobs nearby.

Swimming
Sprint under water to swim. You lie flat and fit through gaps one block tall. Where there is no room to stand, you crawl.

Soul sand under water makes a bubble column that carries you up. A magma block makes a whirlpool that pulls you down, and it sinks boats.

Everything else
Coral comes in five kinds as blocks, plants and fans, and it dies out of water. Sea pickles glow under water. Kelp dries into a quick snack, and a block of dried kelp burns as fuel.

Shears carve a face into a pumpkin, since pumpkins now grow without one. Axes strip logs. You also get prismarine stairs and slabs, bark blocks, trapdoors, buttons and pressure plates in every wood, blue ice, the undyed shulker box and the Potion of the Turtle Master.

Zombies and skeletons sink and walk along the bottom. Squid squirt ink when hurt. Skeleton horses can be ridden under water. Dropped items float.
Kelp, seagrass, coral and the prismarine stairs and slabs hold the water they sit in.
The title screen shows 1.13's ocean panorama.
Every feature can be turned off in Backport Core's settings screen, under Mod Options. Each setting has a plain name and a one-line description, and search finds any of them.

Compatibility
Existing worlds work. The new oceans show up in chunks you have not explored yet.
With Village & Pillage Backport installed, the composter takes kelp, seagrass and sea pickles, the stonecutter cuts prismarine, and cats scare phantoms away.
Commands
/locate structure #minecraft:shipwreck finds the nearest shipwreck. #minecraft:ocean_ruin and minecraft:buried_treasure work the same way.
/gamerule doInsomnia false stops phantoms in that world.
Requirements
Minecraft 1.12.2 with Forge 14.23.5.2847 or newer, and Backport Core 1.1.0 or newer. The CurseForge app installs Backport Core and Fluidlogged API with it.
Also by me: Village & Pillage Backport, Enchantment Recipes, which lets you craft enchanted books from mod materials, and Villager Tomes, which lets you teach a librarian the books you find.
