Summary

An awe-inspiring and panoramic investigation into the hidden world of the deep sea — a mysterious, unforgiving landscape whose secrets radically revise our understanding of life on earth.

The deep sea is one of our planet’s last frontiers. For most of human history, it has been a remote realm shrouded in obscurity. But here, where the light cannot reach, lies a strange, wonderful and breathtaking world, teeming with scientific marvels and lessons for the future of life on this planet.

In The Dark Frontier, marine microbiologist and explorer Jeffrey Marlow plunges us into the ocean’s depths and invites us to witness close-up encounters with its hidden brilliance. Translucent shrimp dance through sulphureous vents, crabs stretch twelve feet from claw to claw and the eerie chalk-white towers of the ‘Lost City’ loom. Immersive and illuminating, Marlow’s journeys reveal alarming warning signs as well: we are irrevocably changing the deep sea before we have even had a chance to understand it.

This expansive book offers crucial and surprising insights into the ways in which the twinned forces of exploration and exploitation have shaped our relationship with the ocean. It shows how life can thrive in even the most extreme conditions, and reveals critical links between the deep sea and life on land. The Dark Frontier expands our understanding of biological possibilities – and our responsibilities – on Earth and beyond.

Critic Reviews

Jeffrey Marlow goes deep—really deep—beneath the sea to explore a world we can't see and can barely imagine. The Dark Frontier is at once an adventure story, a tale of scientific discovery, and a plea for preserving one of the world's most fascinating and fragile environments.

Elizabeth Kolbert, author of THE SIXTH EXTINCTION

Critic Reviews

A brilliant scientist and storyteller, Jeffrey Marlow takes us on a page-turning descent into the deepest mysteries on the planet, revealing a world as strange, beautiful, and edifying as it is essential to our uncertain future. Though witness to the farthest reach of our destructive ways, Marlow leaves us with words of hope.

Critic Reviews

A fascinating, even moving, deep dive into the deepest of subjects . . . As Jeffrey Marlow shows us, the ocean floor isn’t a bleak wasteland—it’s the largest part of our planet, teeming with life and with possibilities for a radically reimagined future. Marlow’s book shines a brilliant light on Earth’s crucial frontier.

Jason Roberts, Pulitzer Prize–winning author of EVERY LIVING THING

Critic Reviews

Dr. Jeffrey Marlow gives readers a front-row seat and a backstage pass to the vanguard of deep-sea science, at a time when this research has never been more exciting or vital. The Dark Frontier is a meticulous, wide-ranging, and riveting book, and an essential addition to the ocean canon.

Susan Casey, author of THE UNDERWORLD: JOURNEYS TO THE DEPTHS OF THE OCEAN

Critic Reviews

This gripping trip to the bottom of the ocean doesn’t just explore many of the otherworldly mysteries lurking in a lightless universe;, it is an illuminating peek into something deeper yet – the nature of life itself.

Dan Egan, author of THE DEATH AND THE LIFE OF THE GREAT LAKES

Critic Reviews

Marlow writes with poetic precision, illuminating the unseen depths of our ocean and giving voice to the silent communities of scientists, explorers, and protectors working at the frontiers of discovery. The Dark Frontier arrives at a critical moment, bridging the vast distance between deep-sea exploration and public understanding—showing us why the ocean's future is inseparably linked to our own.
