## Ocean depth averages
The average depth of the ocean varies by ocean, with the Pacific at 4,280m, Indian Ocean at 3,741m, Atlantic at 3,646m.
## Deepest ocean point
Challenger Deep in the Mariana Trench reaches 10,911m, 13 times taller than tallest building.
## Human access to deep ocean
Only 27 people have descended to Challenger Deep, including Titanic director James Cameron and Hamish Harding.
## Ocean depth zones
The ocean has distinct layers: epipelagic (surface), mesopelagic (twilight zone), bathypelagic (no sunlight), abyssopelagic (4,000-6,000m), hadalpelagic (deepest).
## Deep sea life
Trillions of animals migrate nightly between deep and surface waters, with predators following them.
## Deep ocean threats
Trawling nets damage ancient deep sea corals, risking ecosystem collapse.
## Key takeaway

Challenger Deep in Mariana Trench reaches 10,911m, 13 times taller than tallest building.
