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...
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...
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...
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...
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...
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...
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...
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...
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...
Rip currents are dangerous and fast moving.
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...
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 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...
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...
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.
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...
