For the most part, we don’t know what lies beneath the surface of our oceans.
Most of the waters and ocean floor remain unexplored.
But with new technology, projects are underway to find out what lies in the deep.
Since 2004, a team of scientists has been cruising the Caribbean surrounding Puerto Rico, as well as St. Thomas and St. John islands in the U.S. Virgin Islands to create a comprehensive map of the seabed.
