Depths of the Sea

"To understand what makes Earth different from any other place, and why life can thrive here, it would be logical to focus on the part of the biosphere that supports most of the action -- that is, the sea, of course. Since I am by nature an air-breathing sun-loving mammal, it has taken some time for the awareness to seep into the cracks of my brain that most of the biosphere is ocean. All of life on Earth lives in the dark at least half of the time, and much of it lives in the dark all of the time -- in the depths of the sea." ~ Sylvia Earle, Sea Change

One of the characters in my novel has a background in oceanography; she wanted me to read Sea Change after listening to Sylvia Earle speak with Krista Tippett OnBeing. I'm also going to be reading Rachel Carson's The Sea Around Us and her other two books about the sea.

I've never been much of a sea-person; I'm far more at ease hiking in the woods -- being in the depths of the forest. However, did you know that "almost anyone listening to a recording of humpback whales can identify them as humpback whales--but experts can pinpoint where a song has been sung, and even when." (Earle) Isn't that incredible?
