Drifters deployed into the Gulf of Mexico sent location information back to scientists through a GPS satellite. Some of the 5.7 million data points about the drifters locations are seen in this map...
Expedition data went to the Arctic Ocean Diversity database of the Census of Marine Life to establish a baseline that will help to document change in the poorly known Arctic Ocean. Scientist Kevin...
Dive into the Gulf of Mexico without getting wet! The Smithsonian has recently uploaded some of its marine collections from that region onto Google Earth's Ocean Layer . Now you can go where our...
Dr. Patrick Colin , of the Coral Reef Research Foundation in Palau, examines a sponge he collected off the island of Curaçao, in the Caribbean. Colin is conducting research for the National Cancer...
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.
NOAA’s New Millennium Observatory (NeMO) was set up to study geologic, chemical, and biologic interactions along the mid-ocean ridge system. Learn more about NeMO and watch a video about underwater...
This radio device is used to track North Atlantic right whales. Suction cups hold the device to a whale's back, where it records data such as depth, water, temperature, and underwater sounds. These...
Peter Auster and colleagues direct a Remotely Operated Vehicle (ROV) dive on the New England Seamounts. Three teams composed of three scientists and four ROV engineers take two 4-hour watches every...
Researchers collect underwater noises with autonomous recorders.
The Baltic’s waters are so frigid that the sandy seabed was often frozen during Oceana's 2011 expedition. The divers’ underwater cameras had to be put on automatic settings to take photos, as their...
Leatherback sea turtles ( Dermochelys coriacea ) are listed as critically endangered by the IUCN Red List of Threatened Species. The primary threats to leatherbacks are interactions with fisheries...
On May 31, 2009, this one-of-a-kind hybrid robotic vehicle reached the deepest part of the ocean—the Marianas Trench, located in the western Pacific Ocean, 10,902 meters (6.8 miles) below the surface...
The sea's largest fish has been a mystery until recent decades. Thanks to electronic tags, researchers are uncovering some of the secrets of the whale shark ( Rhincodon typus Smith, 1828 ). One...
A Coral Reef Watch satellite monitors the temperature of the world’s oceans. When ocean waters get too hot, corals release the microscopic algae that provide them with color and, more importantly,...
This is the world’s first unmanned, underwater robot—or “glider”—to cross an ocean basin, the pioneering Scarlet Knight . The robotic glider, also known as RU27, can dive to depths of 200 meters (660...
NOAA is working with students across the globe to place floating buoys throughout the ocean through their Adopt a Drifter Program . The buoys will drift with the help of ocean currents and record the...
