Through exploration, we’re learning more about the ocean's biological, chemical, physical, geological, and archaeological aspects every day. But before we can truly explore, we must map. Learn more about seafloor mapping through our curated education theme: https://oceanexplorer.noaa.gov/edu/themes/seafloor-mapping/welcome.html | NOAA Ocean Exploration
