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...

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...
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...
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...
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...

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...
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.
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...
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...

Orange shaded areas are major drainage basins of Belize, Guatemala, and Honduras that contribute sediment to the Caribbean. Wind and current patterns are represented by red and black arrows,...
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...
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...

The Deepwater Horizon disaster has imperiled the ecosystem along the U.S. Gulf Coast. Most oil spills have occurred at the ocean surface. This one, originating at the ocean floor and rising up...
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.
