Earth's ocean currents 🌊 This data visualization is showing how the ocean moves water across the planet using data from NASA’s ECCO model, or Estimating the Circulation and Climate of the Ocean. The model pulls data from spacecraft, buoys, and more. Researchers rely on the model output to study ocean dynamics and to track conditions that are crucial for ecosystems and weather patterns.

Curious about how and why scientists map the ocean floor? Learn more about bathymetry: the study of underwater floors in oceans, rivers, or lakes! Just like dry land, the surface of the seafloor is not always flat––it can have coral reefs, mountainous ridges, deep canyons, and many other features that can be revealed in bathymetric data. Check out our latest ocean fact to learn more about what bathymetry is and why it is important: https://oceanexplorer.noaa.gov/facts/bathymetry.html | NOAA Ocea
