Under the Deep Blue Sea

At the dawn of the underwater world's televised scuba era, when Jacques Cousteau began to introduce the air-bound world to the wonders of the sea, British marine biologist Trevor Norton was already there; slipping through kelp forests, marveling at the underwater plunge of the cormorant, exploring the seabeds that would become his second home.

We are seven-tenths salt water, he knew as a boy. Our blood and a bucket of sea water are close cousins. We have gills in the womb.

Trevor Norton took to the sea for life. Now he's telling that story, of wonders and waste under the sea around the world.

Hear about life in the sea, and the life of the sea today, with marine biologist Trevor Norton.
