Description
Oceanic Expanse is a Forge mod that backports many ocean-based features from 1.13+ and adds even more new custom content! Each Feature is made to fit and expand upon vanilla Minecraft design and is built to be highly configurable.

Backports and alters many 1.13+ features such as Drowned, Shipwrecks, Conduits, Tridents, all the fish, and much more.
Adds ocean regions such as Frozen Oceans with Icebergs, and Warm Oceans with Coral Reefs.
Expands upon beaches, adding Palm Trees with falling Coconuts, Crabs that dig up treasures, Shelly Sand for beachcombing, and more!
Adds content below Frozen Oceans with the ocean crop Dulse, Tube Sponges, and lots of Sea stars!

FAQ

Q: Why did you make this for 1.12? Isn't that a lot of unnecessary work?
A: I started development on this mod in 2018, and it was the first Minecraft mod I ever developed to completion. Rather than abandon the work done so far, I decided to just finish the 1.12 mod, as it is better to release the mod rather than attempt to keep with the latest version.

Q: Why are some of the content backports, and others fully original?

A: When this mod began development, there weren't many mods backporting content from 1.13 well; so the original purpose of this mod was backporting. Working on it though, I expanded upon parts of 1.13 I felt were lacking such as the Trident, and soon enough began adding more unique content based on what I'd like out of an ocean mod.

Q: Will you port this mod past 1.12 / When will it be on [newer version]?

A: If I port this mod to a later version, many features will need to be changed/altered. As such, expect it to be a sequel, like Oceanic Expanse 2: Electric Jellyfish!!1!
Also, please don't beg for a port. This is not my job, nor is it my duty. I will port it if I want to, when I want to.

Q: Will you add X feature?

I have multiple documents used for planning, expect them to be made public in the future. As for adding features, I am very picky on what I want to add. So many things you might want (like sharks) will likely never be added.

Fluidlogged API adds fluidlogging, similar to 1.13+ waterlogging, but supporting any fluids, including those added by mods!
