Why do creatures glow in the dark miles below the waves? What could be lurking in the Mariana Trench? And why do some ocean parts remain a mystery—even to scientists?

Into the Deep is your gateway into Earth's last unexplored frontier: the ocean. With 10 captivating chapters that unravel the deep sea's most astonishing, mysterious, and mind-bending phenomena, this book is crafted for curious minds of all ages. Whether you're a budding marine biologist, a lifelong ocean lover, or someone who marvels at the wonders of nature, this journey into the abyss will leave you awestruck.

Covering everything from the haunting glow of bioluminescent creatures to the high-pressure worlds of hydrothermal vents and deep-sea trenches, each chapter delivers a digestible, engaging, and scientifically sound exploration of some of the most elusive topics in oceanography.

Dive into the crushing depths of the Mariana Trench, where alien-like organisms thrive without sunlight. Discover the eerie beauty of bioluminescence—living lights that dance through the darkness. Trace the path of the global ocean conveyor belt, an underwater superhighway that regulates Earth's climate. Examine the bizarre creatures of the twilight zone, a layer of ocean so dim and so mysterious that it remains one of the least understood habitats on the planet.

You'll encounter squids once believed to be myths, uncover the origins of the strange sounds recorded by ocean microphones, and learn how plastic pollution is reaching even the most remote ocean trenches. Along the way, you'll gain insight into how scientists are gradually mapping the ocean floor despite the immense technical and environmental challenges involved.

Written by science communicator Serena Quillan, Into the Deep brings clarity to the complexity of marine science with warmth, curiosity, and plainspoken insight. Each topic is explained without jargon but with deep respect for science and the ocean.
