🌊 OCEANOGRAPHIC ENCYCLOPEDIA • 0m TO 11,034m DIVE MAP
The 5 Oceanic Depth Zones in The Endless Dive
Every meter of descent in The Endless Dive mirrors real-world oceanography. As you answer obscure category prompts, your vessel plunges through 5 distinct ecological and physical layers. Learn the pressure thresholds and biological milestones of each depth tier.
01
0m – 200m Epipelagic Zone (Sunlight Layer)
Hydrostatic Pressure 1 – 21 ATM (up to 308 PSI)
Light Penetration 100% – 1% (Photosynthesis Active)
Water Temperature 24°C – 18°C
Submarine Spec Standard Commercial Submersible Hull
Resident Fauna: Dolphins, Bluefin Tuna, Sea Turtles, Phytoplankton
Trench Strategy: The Surface Crowd Trap Zone. Answers chosen by over 25% of players keep your vessel stranded in this layer. You must immediately deploy obscure knowledge to break through the 200m thermocline boundary.
02
200m – 1,000m Mesopelagic Zone (Twilight Layer)
Hydrostatic Pressure 21 – 101 ATM (308 – 1,484 PSI)
Light Penetration 1% – 0.001% (Faint Blue Shimmer)
Water Temperature 18°C – 5°C
Submarine Spec Reinforced HY-80 Steel Pressure Hull
Resident Fauna: Lanternfish, Barreleye Fish, Hatchetfish, Bigfin Squid
Trench Strategy: The Transition Layer. Answers with 10% to 25% submission frequency hover here. To descend further, stop submitting familiar pop-culture trivia and pivot toward historical dates and scientific terminology.
03
1,000m – 4,000m Bathypelagic Zone (Midnight Layer)
Hydrostatic Pressure 101 – 401 ATM (1,484 – 5,893 PSI)
Light Penetration 0% (Perpetual Absolute Darkness)
Water Temperature 5°C – 2°C
Submarine Spec High-Strength Titanium Alloy Sphere (Grade 5)
Resident Fauna: Vampire Squid, Gulper Eel, Anglerfish, Giant Isopod
Trench Strategy: The Deep Water Threshold. Requires answers submitted by 3.5% to 10% of players. Pressure begins to tax your submarine ballast; single common mistakes result in catastrophic buoyancy blow-outs.
04
4,000m – 6,000m Abyssopelagic Zone (The Ocean Abyss)
Hydrostatic Pressure 401 – 601 ATM (5,893 – 8,832 PSI)
Light Penetration 0% (Only Bioluminescent Flashes)
Water Temperature 2°C – 1°C
Submarine Spec Thick Cast-Titanium Capsule (60mm+ thickness)
Resident Fauna: Dumbo Octopus, Faceless Cusk, Deep-sea Anemones, Sea Pigs
Trench Strategy: Extreme Depths. Covers the vast abyssal plains of the Pacific floor. Only submissions under 3.5% frequency survive. You must rely on deep geography (micronations, island enclaves) and obscure literature.
05
6,000m – 11,034m Hadopelagic Zone (Trench Trenches & Challenger Deep)
Hydrostatic Pressure 601 – 1,086 ATM (8,832 – 15,960 PSI)
Light Penetration 0% (Complete Void)
Water Temperature 1°C – 4°C (Hydrothermal Vents)
Submarine Spec Specialized Deepsea Challenger Syntactic Foam & Forged Steel Sphere
Resident Fauna: Pseudoliparis swirei (Mariana Snailfish), Supergiant Amphipods, Xenophyophores
Trench Strategy: The Ultimate Victory Zone. Found only in deep oceanic trenches (Mariana, Kermadec, Puerto Rico). Over 1,000 atmospheres of pressure will crush any vessel that enters an answer above 1.2% global popularity.
