The most recommended books about deep sea exploration

My Goodreads review of this book just says, “Yes yes yes yes yes this is the good stuff,” if you want a sign of my emotional reaction to Our Wives Under the Sea.

This is a gorgeous, compact, spooky, haunting novel about a marriage falling apart, and it came into my life at exactly the right time. Miri’s wife, Leah, is an undersea explorer who vanishes for months under the water without a trace. Finally, she returns—but has all of Leah come back?

I would call this half dark fantasy horror, half contemporary queer literary fiction. Or Mitski meets The Haunting of Hill House. It checked all my boxes, and I whipped through it in two sittings. In other words, “the good stuff.”

Ann Elias demonstrates how visual media – photography, film, art, and museum displays – re-cast coral reefs in the early 20th century from dangers to navigation into fantastical but familiar and inviting spectacles. Coral Empire reveals photographers, artists, and scientific explorers as they rendered the undersea modern yet colonial. Using technology, indigenous knowledge, and their own visions, they presented the oceans as wild, untouched spaces full of resources that invited exploitation, conquest, and tourism. Desire-fueled uses of the undersea obscured the destructive nature of human activities on coral reefs, now abundantly apparent, while the power of the visual for imagining and knowing the undersea remains.

I highly recommend this true tale of deep-sea exploration!

The suspense is intense, compelling readers to keep turning pages. In 1930, two intrepid explorers climbed into a 5,000-pound hollow metal sphere and descended 800 feet into the ocean—farther than any human had ever dared to venture. They were amazed to find animals aglow in the ocean’s cold, dark depths.

Young readers (and older readers, too!) will be inspired by Otis and Will’s desire to know more, their persistent problem solving, and this remarkable feat of science and engineering. Over 90% of the ocean is still unexplored! Well-researched pencil, ink, and watercolor illustrations suit the story perfectly.

Another great book rife with tension and terror, about a team who go in search of what killed their friends and loved ones, a nightmare recorded on video but hard to believe, a terror buried in the depths of the Marianas Trench. I love this fascinating take on mermaids, how the book keeps you on tenterhooks the whole time, waiting to see what will happen, who is next, and what sort of monsters we haven't even seen yet.

This is the story that first got me interested in science fiction. Of course, we now recognise some of the flaws in the science, but consider that at the time of its writing steam propulsion was still in its infancy, most ships were still built of timber, and Verne envisaged a ship capable of indefinite travel beneath the ocean surface – something not even possible until the advent of nuclear power almost a century later. Even today Verne’s vision and the story he wove around it can inspire.

For a while space and the deep oceans were a matched set of explorations – even Arthur C. Clarke wrote parallel novels about space and sea - then they diverged. What space promised, however, the oceans delivered – new maps of the solid Earth, a new geology, new biotas, and life forms.

No comprehensive survey of all that exploration yet exists. But Robert Ballard’s Eternal Darkness gives access to what happened and some of the critical discoveries, even if it grants attention to the sunken Titanic as well as to black smokers. Deep sea discovery doesn’t have a grand narrative akin to the space race to the Moon or Voyager’s mission to the outer planets; instead, it has biographies like that for the submersible Alvin and pioneers like Ballard. A readable introduction, with some thoughtful conclusions.
