Tides & Currents

Tides and currents move large amounts of water around the world’s oceans, as well as nutrients, oxygen and heat. Currents influence weather patterns and tides are relied on for maritime safety due to their extremely reliable nature.

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...
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...

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.
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...
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...
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...
