NOAA Multibeam Mapping Diagram

Image shows a diagram of multibeam seafloor mapping

Detailed Description

An illustration from NOAA of how a ship like the R/V Falkor collects multibeam data. As the ship sails, multiple sound waves are sent out from the multibeam echosounder. These soundwaves then reflect off both the ocean floor and things in the water column, like bubbles from a methane seep. As the soundwaves reflect back to the ship, the multibeam echosounder receives the waves and interprets the data so that GIS specialists like Bill can create visualizations, not just of the ocean bottom, but of the entire 3-dimensional space beneath the ship.
