Abstract
Following hurricanes Katrina and Rita, many types of acoustic systems were used to assess the effects of the storms. Swath multibeam sonars were used to survey erosion in ports, channels, and estuaries. Sidescan and scanning imaging sonars were used to locate debris, obstructions, missing oil platforms and ships, and dislocated pipelines. Acoustic positioning systems and acoustic modems were used to support the sonar imaging systems. A wide array of acoustic systems were used in the overall effort. Samples of data from several types of sonar systems will be presented along with discussions of the challenges of collecting data in a real-world environment.
