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
