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

Over the next several days, we're going to explore how seafloor mapping truly is the foundation for healthy oceans and a healthy planet. We'll start by looking at how we use sonar systems to map the seafloor, one "ping" at a time: http://oceanexplorer.noaa.gov/world-oceans-day-2015/mapping-the-seafloor-one-ping-at-a-time.html | NOAA Ocean Exploration

As things continue to ramp up for ocean exploration in 2023, we'd like to take a moment to reflect back on all of the activities, discoveries, partnerships, and outreach that made 2022 such a great year: https://oceanexplorer.noaa.gov/about/annual-reports/annual-report22/annual-report-2022.html. Onward and downward! | NOAA Ocean Exploration

Despite its importance, the majority of our ocean is largely unknown. 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.
