  1. Multibeam Sonar Operations and Applications 1994—2005 NOAA’s Experience

  2. The Early Era • 1984/5 BS3 on Davidson • Charting surveys in Alaska • 1985—1994 EEZ surveys • SeaBeam [12] (MI, SU, DI) • BS3 (DA) & HydroChart II (WH)

  3. Getting into Shallow Water • 1992 Hurricane Andrew • How to clear navigable waterways? • RESON 9001 • 1994 RESON 9001 on NOAA Ship RUDE • Least depth on SSS-detected targets

  4. Beginning Systematic Surveys • 1994 Reference Mile • RUDE with Reson 9001 • 1995 Full-coverage SWMB surveys • SAIC in Long Island Sound • 1997 RUDE in approaches to Portsmouth, NH • Reson 9003 skunk stripes and full coverage SWMB supplemented with 100% or 200% SSS. • 1998 Multiple contracts in Gulf of Mexico • Skunk stripe MB with 200% SSS

  5. RUDE Reson 9003 SeaBat System (1994) Contract Survey comparison

  6. Storing & Processing the Data • 1993-1996 —logging & decimating the data to identify shoalest soundings with in-house software (Huff) • 1995—HyPack/Isis combo selected for NOAA data acquistion and logging • 1995—CARIS HIPS selected for NOAA MB data cleaning & processing • 1995 CARIS compatibility required for contractor data submission

  7. The Current Era • 1998 SWMB for RAINIER and Launches • ELAC/SeaBeam 1050D (50/180) on ship • RESON 8101 on launches Our first RA project—Shakan Strait, Alaska

  8. The Current Era • Today in the Hydro Fleet (RA, FA, RU, TJ, NRTs) • ELAC/SeaBeam 1050D, 1180 • RESON 8101, 8125, 8111,8160 • Simrad EM 3000, 1002 • Side Scan Sonar—still important • Klein 3000 & 5000

  9. Reference Block

  10. Data Acquisition and Processing • HyPack & Isis combo for data acquisition • Data stored in XTF • CARIS HIPS and SIPS for processing • PYDRO for target management\ • Down sampling to smooth sheet and chart density

  11. The Coming Era • Phase comparison systems in the mix • Surveying on the Ellipsoid • Re-assessing XTF vs GSF vs native formats • CUBE • Bathymetric Attributed Grids (NavSurface) • Full density products for next generation ENCs

  12. The Coming Era—Beyond Hydro • Habitat, UNCLOS, and water column surveys • Multibeam throughout the NOAA fleet • SeaBeam on BROWN, TBD for the future • EM 300 and dual-head 3002 on HI’IALAKAI • EM 1002 to be installed on NANCY FOSTER • EM 3002 for Gloria Michelle • TBD for CAPABLE • TBD for new Fisheries vessels

  13. Burning Issues • Expectations vs specs vs actual capabilities • System integration • System timing management • Sound speed characterization • On-line quality control aids • Backscatter • Common terminology • Calibration • Interpretation • Products • Data archiving

  14. More Burning Issues • Forward-looking sonar for refraction • Standards for archiving • Automated cartography from BAGs • Standards for error specifications • Target recognition and detection
