Diving Deep by Michelle Cusolito


Diving Deep: Using Machines to Explore the Ocean
by Michelle Cusolito; Illustrations by Nicole Wong
Charlesbridge. 2022

This delightful informational picture book explores the different machines and equipment people use to explore the ocean.

“From snorkeling to free diving, scuba, submarines, and Challenger Deep.”

The text is poetic and set in white on Wong’s full-page, beautifully illustrated pictures created digitally on an iPad using Procreate. 

What drives humans to dive into the sea and sink deeper than the last inkling of light?

We are wired for wonder.

We delight in discovery.

For some, 

danger is the draw.

Other chase the thrill

of an unseen seascape—

to confront unknown

and push the limits of exploration.”

The double-page spreads includes a brief statement of how the tool is used, along with a scientific explanation of the machine or equipment being shown in the illustration. 

The book ends with possibilities: “Today, we explore a lush landscape deep below Antarctic ice. Tomorrow we may unlock more secrets of life on Earth.”

An author’s note, a note about measurements, glossary, and additional resources is included. 

A beautiful, inspiring book to spark questions for all level of readers.

Pair this with Cusolito and Wong's companion book, Flying Deep: Climb Inside Deep-Sea Submersible ALVIN.


  1. I'm so excited to see this. My niece is an engineer currently designing and building drone submarines. Currently they are tracking migrating whales so that wind turbines will be turned off when the whales are in the area. I'm getting a copy of this for her!

    1. That is super cool! I'd love to know more about it.

  2. Thank you so much! I'm glad you enjoyed it.
