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 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.
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...
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...
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...
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,...
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...
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...

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...
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...
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...
