Abstract
In this live interactive video session, scientists onboard the R/V Roger Revelle in the Philippine Sea off the coast of Taiwan describe the basic concept of sound propagation in the ocean in the context of an ongoing acoustic mooring deployment. Six acoustic source moorings and a distributed hydrophone array will be deployed during the course of the month-long cruise. The scientists will give an introduction to how research is carried out at sea and will describe basic concepts and advantages of using acoustics as a tool to learn about the ocean environment. They will show examples of oceanographic instrumentation, including conductivity-temperature-depth sensors, acoustic sources, and hydrophone receivers, and will describe the process of deploying acoustic moorings and acquiring oceanographic data. The girl scouts will learn how sound is used to map the 6-km deep ocean floor as well as how tomographic moorings can be used to sense the ocean interior. There will be the opportunity to interact with scientists on the research ship and ask questions about ocean acoustics or life at sea. [Field work supported by ONR.]
