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...

At the entrance of most beaches, there is a bulletin board with notices about water conditions: maybe a faded sign warning...
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...
Rip currents are dangerous and fast moving.
A screen capture from NOAA's NowCoast website which displays real-time weather data, including current speeds, projected hazards, temperature and wind speed. Real-time data is helping scientists work...
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...
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...
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...
CREDIT: Provided by Rutgers University Glider Technology Now Used to Study Oil Spill in Gulf of Mexico The first underwater robotic vehicle—or “glider”—to cross an ocean is the centerpiece of a new...
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...
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...
The Woods Hole Oceanographic Institution's "Line W" program is conducting research to better understand how the oceans and the atmosphere work together to cause, and are affected by, climate...
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...
Animals, on land and in the ocean, live in a 3-D world, and they depend on their sense organs and brains to build the mental constructs that allow them to orient and navigate, which is crucial for...
As a geological oceanographer at the Smithsonian National Museum of Natural History, Dr. Maggie Toscano has made a career of documenting how coastal systems have changed over thousands of years in...
Part 5 of a 6-part series describing Woods Hole Oceanographic Institution's efforts to understand the scope and impact of the Deepwater Horizon oil spill in the Gulf of Mexico. "Tracking the Currents...
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...
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...
