Like marine mammals using sound to “see” their underwater environment, scientists also use sound to determine what the seafloor looks like! Mapping the seafloor provides information for many purposes, including safe navigation of fishing vessels and helping pinpoint where marine animals call home. Join us as we discuss the tools of the trade for mapping the seafloor and the many ways that data is used by scientists for everything from charting the ocean to understanding habitat.
