Deep Cold Ocean
Overworld (water)
Cold ocean water sunk to twice its depth: dark indigo over a gravel floor, salmon and cod between the kelp, and ocean monuments lurking where no land is in sight.

Resources
- Ocean monument loot: sponges, gold blocks, prismarine
- Salmon and cod in schools
- Kelp and sparser seagrass on the gravel floor
- Extra tall seagrass compared to the shallow cold ocean
Mobs
- Salmon and cod; dolphins in Bedrock
- Squid, glow squid and nautiluses
- Guardians and elder guardians; drowned that can ride zombie nautiluses
Structures
- Ocean monuments
- Shipwrecks and cold ocean ruins
- Never borders land - only cold oceans, deep oceans, deep frozen oceans and mushroom fields
Why go
- The cold-zone monument hunt
- Reliable salmon fishing over deep water
- Atmospheric deep-sea builds far from any coast
Tips
- Follow a cold ocean out to sea: the moment the floor drops to about Y=30 you are in monument territory.
- Doors, magma columns or a conduit give you air on long dives.
