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...
By Emily Frost Throw a message in a bottle into the vast ocean and where does it go? The answer to this question is not just a romantic curiosity. Thinking about where a small floating item might end...
When you look underwater, what is making the seagrass wave in the water? The answer is ocean currents . Ocean currents are continuous movements of water in the ocean that follow set paths, kind of...
Since 1902, more than 40 centimeters of mangrove peat could have accumulated at the Belize site, enough to entrap and bury small pieces of pumice. But Juan’s vexing questions persisted: Why hadn’t...
A boat full of SCOPE drifters waits to release small, biodegradable buoys that will travel throughout the Gulf of Mexico and send GPS coordinates to researchers. This is the second experiment by...
Scientists met the robotic glider Scarlet Knight about halfway along its journey of scientific exploration from the United States to Spain, discovering that barnacles were growing on the glider’s...
Researchers launch one-meter-tall plastic drifters into the Gulf of Mexico in 2012. Over 300 of these drifters were released and their location information was sent to researchers every five minutes...

In the Pacific Ocean, four ocean currents merge to form the North Pacific gyre, also known as the North Pacific Subtropical High, which spans the western US to Japan, and Hawaii to California. This...
Ocean conditions change every hour of every day. Tides, currents, and winds are constantly in flux. NOAA’s real-time data helps huge ships navigate safely under bridges and around obstacles. Explore...

At the entrance of most beaches, there is a bulletin board with notices about water conditions: maybe a faded sign warning about rip currents and a list of this week's tide tables. Most people pass...
If you think only men can helm research vessels to get their hands dirty and study ocean currents, you're wrong. This short film follows the mostly-female scientists of the R/V Knorr research ship on...
The first unmanned, underwater robot or glider Scarlet Knight maneuvers through the dangerous opposing and circular currents in swirling eddy fields of the Atlantic Ocean to collect data below the...
Pink dye was released along the coast of the Gulf of Mexico by CARTHE researchers and its movement tracked using underwater sensors, two small drones, a helicopter and a kite. In this photo you can...
