How do explorers chart the seafloor under miles of ocean? With bathymetric or “wet” maps! We bounce sonar off the seabed to build a detailed picture of an area’s shape. That data then helps us identify and map all kinds of structures, from trenches to undersea mountains. Our website features a lesson plan for teachers to help students understand wet maps and their uses. If you’re not a teacher (but still feeling crafty) why not give it a try yourself? You can find the materials and instructions

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.
