Deep Sea – Deep Secrets: Exploring and Understanding the World Beneath the Waves

The oceans cover more than 70% of the Earth’s surface. We are just beginning to understand the oceans’ role in human origins, evolution, and destiny. They provide half of the oxygen we breathe, most of the fresh water we need, and protein to more than one billion people. Despite these facts, we have explored only 8% of the oceans.  In that fraction of the world’s oceans, we have found the planet’s greatest mountain range, thousands of deep valleys, and animal communities that rival the tropical rainforests in diversity and density. For more than 25 years, Dr. Gallo has been at the forefront of ocean exploration. He has participated in expeditions to all of the world’s oceans and was one of the first scientists to use a combination of robots and submarines to explore the deep seafloor.
