Dive!

"[An] introduction to the comprehensive world history of diving . . . How do you breathe underwater? What tools can we use to go deeper and deeper into the oceans? And...what's down there?

Dive deep into our long history of sea exploration to learn why, how, and when humans have dived, and uncover our biggest questions about what hides in the Earth's deepest waters"--Provided by publisher.
