The “garbage patches,” as referred to in the media, are areas of marine debris concentration in the North Pacific Ocean, circulated by the North Pacific gyre. The gyre spreads across the Pacific Ocean from Japan to the western US...

EPA divers from Atlanta place this instrument in Charleston Harbor in order to monitor currents and better predict sand movement for a harbor deepening project.
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...
The arrows show the direction of ocean currents recorded by William Dampier while crossing “La Grande Mer du Sud”—the Pacific Ocean. The map appeared in Dampier’s second book, Voyages and...
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...
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...
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...
This video, produced by Waterlust, shows how the Consortium for Advanced Research on Transport of Hydrocarbon in the Environment (CARTHE) uses drifters to collect important data about the ocean...
The Bay of Fundy in Nova Scotia, Canada has the highest tidal range. The tides range from 3.5m (11ft) to 16m (53ft) and cause erosion to the landscape, creating massive cliffs.
Rip currents are dangerous and fast moving.
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...
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...
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...
But what path, precisely, did this pumice take to reach Belize from the Guatemalan Highlands? Maps of drainage networks that reach the Gulf of Honduras and currents in the western Caribbean Sea are...
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...
To protect Venice from rising seas, Dimitri Deheyn (Scripps Institution/UC San Diego Sediment Research Group) studied the environmental impact of dredging sediment from the waterways. Managers...
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...
