Figure 1. This target found in Area 1 may be a barge, but its identification has not been verified. The images were generated by a REMUS 100 SW AUV with a dual-frequency sidescan sonar. One image (on the left) shows the entire target captured by the 900-kHz sonar. Other detailed images (to the right) — showing hatches, cable, and other objects — were generated by the 1800-kHz sonar.Image courtesy of AUVfest 2008: Partnership Runs Deep, Navy/NOAA, OceanExplorer.noaa.gov.
