00:00Our world is mostly ocean, yet its deepest parts remain a mystery.

00:04We've mapped the moon and sent rovers to Mars, but oceanic trenches,

00:08Earth's deepest, darkest places are still largely unexplored.

00:12Imagine a canyon deeper than Everest is tall, the Mariana Trench plunges nearly seven miles down.

00:19These trenches are formed by tectonic plates colliding and one sliding beneath the other,

00:24creating immense, narrow scars on the seafloor.

00:27They're not just geological features, they're dynamic, ever-changing, and vital to our planet's evolution.

00:34For centuries we thought these depths were lifeless voids.

00:38But every expedition reveals new life and geological wonders.

00:42The deep trenches are a library of natural history, and we've only just begun to read the first page.

00:48What secrets do they hold?

00:50What strange creatures and clues to Earth's origins might be waiting in the abyss?

00:54The call of the deep is irresistible, promising discovery with every descent.

01:00These are the last true wildernesses on our planet, challenging our understanding of life itself.

01:06Each journey down rewrites what we know about our world.

01:10The story of the trenches is one of the greatest tales of exploration left for us to tell.

01:15They are the planet's great recycling centers, where old seafloor is reborn.

01:19The forces at work here drive earthquakes, volcanoes, and even create new land.

01:24The deep ocean trenches are a testament to the power and mystery of our planet.

01:29And we are only at the beginning of their story.

01:32The trenches are a world of extremes, total darkness, crushing pressure, and icy cold.

01:37Sunlight fades after a few hundred meters.

01:40By trench depths, it's an eternal night.

01:42Pressure here is over a thousand times greater than at the surface, enough to crush ordinary

01:47vessels and unadapted life.

01:50Temperatures hover just above freezing, creating a brutally cold, stable environment.

01:56For years, scientists believed nothing could survive here.

01:59But life is endlessly inventive.

02:01Creatures have evolved to sense without sight, withstand immense pressure, and find energy

02:06without sunlight.

02:07The challenges of the deep haven't prevented life.

02:10They've sculpted it into something unique and resilient.

02:14These adaptations offer profound lessons in survival and the possibilities for life elsewhere

02:18in the universe.

02:20The deep is not a barren wasteland, but a crucible of evolution.

02:24Every organism here is a marvel of adaptation.

02:28The trenches show us the tenacity of life in the harshest conditions.

02:32And they remind us how much we have yet to discover.

02:35Trenches are the front lines of plate tectonics where Earth's crust is recycled.

02:40Subduction carves out these immense V-shaped valleys, the deepest scars on our planet.

02:46Hydrothermal vents erupt here, spewing mineral-rich water and building towering chimneys.

02:51Cold seeps bubble with methane and hydrogen sulfide, creating unique habitats.

02:56These features support entire ecosystems, independent of sunlight.

03:00The trench floor's mud is a geological archive, recording millions of years of Earth's history.

03:07By studying these layers, scientists unlock stories of past climates and ancient life.

03:13The geology of the abyss is not just dramatic, it's a priceless record of our planet's past.

03:18And it's still revealing new secrets with every expedition.

03:23In the trenches, life finds energy in unexpected ways.

03:27Marine snow, organic debris from above, feeds scavengers and decomposers.

03:32Around hydrothermal vents and cold seeps, bacteria harness chemical energy, forming the base of a unique food web.

03:38This discovery proved life can thrive without sunlight.

03:41The creatures here are extraordinary, the gelatinous Mariana snailfish, giant amphipods, ghostly octopuses, and glowing sea cucumbers.

03:50Many are blind, relying on feelers or chemical senses to navigate the darkness.

03:55Some produce their own light, bioluminescence, to hunt, mate, or evade predators.

04:01Every adaptation is a marvel of evolution, perfectly suited to the abyss.

04:05The deep is alive with faint signals and glowing lights, a hidden conversation in the dark.

04:12These outposts of life challenge everything we thought we knew about survival.

04:16And they hint at what might be possible elsewhere in the universe.

04:19Why do we explore the trenches?

04:22They're a frontier of scientific discovery.

04:25Studying life here reveals the limits of biology and may inspire breakthroughs in medicine and technology.

04:31Chemosynthetic ecosystems offer clues to how life might exist on other worlds like Europa's hidden ocean.

04:38Trenches also regulate Earth's climate, locking away carbon for millennia.

04:43Understanding these processes is vital for our planet's future.

04:46Each dive answers some questions and raises many more.

04:50The deep oceanic trenches remain one of Earth's last great mysteries.

04:54They remind us how much there is left to learn and how much we have to protect.
