On her maiden voyage the Royal Mail Ship Titanic struck an iceberg in the North Atlantic just before midnight on April 14th, 1912. Dr. Robert Ballard first discovered the ship's wreckage in 1985...
Scientists on the tiny island of Moorea, in the Pacific, are gathering one of every life form large enough to pick up with tweezers. They're on a quest to build a detailed catalog of the entire...
Welcome to Moorea, a tiny, isolated island in the middle of the vast Pacific. Moorea is 132 square kilometers (51 square miles) of tropical ecosystems – from jungle and wetlands to beaches and coral...
A cable connects a remotely operated vehicle (ROV) to a ship at the surface, where it is operated by a pilot onboard the ship. The cable can extend for miles into the deep sea.
Dr. Robert Ballard poses with an unmanned submersible, like the one he used when locating and exploring the wreck of the RMS Titanic. A veteran explorer, former U.S. Navy Commander, and professor of...

Diving to survey, sample, and manage marine life takes a great deal of skill and knowledge. This diver is sampling the seafloor, also known as the benthic zone. This kind of sampling is important for...
Researchers use Autonomous Reef Monitoring Structures (ARMS) like this one to study the diversity of coral reef organisms. They leave the structures underwater for about a year. Then they retrieve...
Traveling aboard the Charles W. Morgan , a 173-year-old whaling ship on its 38th Voyage, I’m struck by its paradox: this vessel which spent years chasing and killing whales is now helping us to study...
Using a deep-diving ROV, the crew aboard Oceana’s research vessel Ranger were surprised to discover large colonies of deep-sea white coral in the Western Mediterranean Sea in July 2010. Most of the...
Algae, like all organisms, normally grow in balance with their ecosystems, limited by the amount of nutrients in the water. But sometimes, certain species of algae reproduce so rapidly that they...
