The illustrations! It's mind-blowing!

It feels like I am right there at the bottom of the ocean and exploring it's world.

Amazing book with good information and practical tips for divers and those who are interested in exploring the oceans.

Get this book. It's interesting, engaging and informative.

Thank you, Charlesbridge, for the advance reading copy.

A very beautifully made non-fiction book with gorgeous illustrations. I was intrigued by the cover immediately and can imagine lots of children falling in love with it.

This book explains its purpose and delivers on it. The purpose is to tell readers about the different machines used to explore the ocean depths and the reasons that motivate people to explore these depths. The book begins by explaining snorkeling, free diving, scuba diving and more, and ends with the deepest dive to Challenger Deep. For each machine, readers learn how deep it can go, how long it can explore, and how many people are needed to do the exploring. The other purpose of the book is to explain why people explore the ocean depths. The reasons offered are that we are "wired for wonder" and we "delight in discovery." The text is clear--a mix of fact and feelings of awe for life in the ocean.

The dark blues and black illustrations give readers a sense of traveling down to the ocean depths while lighter greens, blues and purples show the upper reaches. Words and illustrations work beautifully together.

Perhaps this book will raise more questions about studying the ocean depths. Readers can move on to learning about ocean explorers, their findings, and the questions still unanswered. That's what informational books should do--tell us new things and stimulate our interest in learning more.

I read this book not as someone who has kids, but as an adult who would desperately love to get Scuba certified and live in the ocean. Alas, I have a medical condition that prevents me from exploring the ocean so I must live vicariously through others. When I saw this book, I immediately had to have it; I didn't care that it was meant for kids. And it did not disappoint! It gave me all the feels. I felt like a kid in a candy store that was told they got whatever they wanted. I finally understood how kids can read the same book over and over and over again and still be enthralled. The illustrations were gorgeous. Like I want prints of them all over my house gorgeous. Even after reading the text, I gazed in awe at their beauty. I would definitely 10/10 recommend this. If I could give it over 5 stars, I would. Immediately after posting this review I will be going to see what other books this author has posted.
