Multibeam Sonar


We head into the ocean for a look at new technology designed to keep our coastline safe for seagoing vessels. See how NOAA (The National Oceanic and Atmospheric Administration) is mapping the coastline off Oregon’s coast using multibeam sonar. Join the crew of the research vessel Rainer as they plot the depths of the Columbia River Bar and Grays Harbor in Washington state. As well as the historic wreck of the Admiral Benson passenger ship.
