7 Sediment Acoustics Experiment (SAX99) Part of High Frequency Sediment Acoustics DRI (FY98-02) Motivation: Better understand acoustic processes associated with detection of buried mines in sandy sediments Frequency: khz
8 Detection of Mines Buried in Sand Understanding shallow grazing angle detection of buried mines requires knowledge of the penetration into, propagation within, and scattering from sand sediments Signal = Penetrate/Propagate/Target/Propagate/Penetrate Noise = Scatter from Sediment Above critical angle: simple picture.
9 Site of SAX99
10 APL-UW Measurements at SAX99
11 Diver Inserting Hydrophones Through Cofferdam QuickTime and a Sorenson Video decompressor are needed to see this picture.
12 SAS Image of Proud Target SAX99 Site 9 m 9 m CSS Image, 180 Hz
13 For a given ripple wavelength, there will be a cut-off frequency, above which lowest-order scattering will not occur. Dominant Subcritical Penetration Mechanism Data/model comparisons indicate that the dominant mechanism is scattering due to sand ripples. First order perturbation theory gives cos θ 2 = (c 2 /c 1 ) (cos θ 1 λ 1 / λ r ).
14 Transmission Across Water/Sand Interface at Shallow Grazing Angles
15 Site of SAX99
16 SAS Image of Ripple Field Target Field Site 9 m 9 m CSS Image, 180 khz
17 Target Field Site Average ripple wavelength: ~70 cm At 20 khz first-order scattered field evanescent (cutoff) for grazing angles < 13 Suggests ripple field not favorable for low grazing angle detections of buried targets using 20 khz SAS system
18 CSS SAS Image of Buried Target at 20 khz Target depth 15 cm Grazing angle 10º Image 9 m 9 m Critical angle 30º
19 CSS SAS Image of Buried Target at 20 khz Target depth 50 cm Grazing angle 4º Image 9 m 9 m Critical angle 30º
20 Buried Target Detections Results better than expected from penetration measurements at SAX99 site - Ripple height not measured at Target Field site Detection results not completely consistent - Target at 15 cm depth detected once in three chances - Target at 50 cm depth detected on all five chances
21 Special Issue Publications IEEE Journal of Oceanic Engineering Special issue on high-frequency acoustics, January Two overview papers on SAX99 Special issue on high-frequency sediment acoustics, July Thirteen papers on SAX99 results - Guest editorial
22 Continuing Research on Target Detection Joint project with APL-UW and CSS Measurements at CSS test pond with artificially generated ripple Results at 20º grazing angle show enhanced detection over first -order perturbation theory predictions as ripple heights increase - Enhancement not yet observed at 10º
23 Planned SAX04 Research (Sept. - Nov. 2004) Fundamental examination of penetration into, propagation within, and scattering from sand sediments - Expanded frequency coverage (1-500 khz) - Detailed environmental characterization (as in SAX99) SAS imaging of proud and buried targets using bottom mounted rail system
24 Portion of SAX04 Bottom Mounted Rail System Total length 50 m
25 SAX04 Updates Pre-mine burial chirp sonar survey of SAX04 site - Schock, April Mine burial May - R/V Savannah Classified data Possible vibracore survey of SAX04 site
26 SAX04 Updates Diving during SAX04 Site surveys in September - Side scan, Caruthers - Multi-beam, Mayer - Chirp sonar, Schock
27 Marine Acoustics, Inc. - Bill Metzger - Kathleen Vigness Raposa Fish: best sensitivity Hz Sea turtles: best sensitivity Hz high hearing thresholds db Marine Mammals Environmental Assessment Ridgway et al. 1997, 3-75 khz, 1 s tones - bottlenose dolphins Schlundt et al. 2000, extended work down to 400 Hz - included beluga whales
28 Environmental Assessment Result: - Change in behavior: 185 db re 1 µpa - Temporary threshold shift (TTS): 195 db re 1 µpa Current thought is that total energy is a more appropriate metric Marine Acoustics is now using these levels: (for whales and dolphins) - Change in behavior: 186 db re 1 µpa 2 -s - Temporary Threshold Shift (TTS): 195 db re 1 µpa 2 -s - Permanent Threshold Shift (PTS): 215 db re 1 µpa 2 -s
29 Thresholds: Environmental Assessment - Change in behavior: 186 db re 1 µpa 2 -s - Temporary Threshold Shift (TTS): 195 db re 1 µpa 2 -s - Permanent Threshold Shift (PTS): 215 db re 1 µpa 2 -s Highest projected SAX04 levels reported to date: - NSWC-PC db re 1 µpa 2 -s at khz 189 db re 1 µpa 2 -s at khz - APL-UW 188 db re 1 µpa 2 -s at khz We should be able to operate at night for essentially all measurements
30 Pelican Boatracks - Through ship, for short messages - Free if not overused SeaNet - Suitable for attachments, not free From Ships Seward Johnson SEAWAVE.com - Individual PIs can sign up (even on ship) - Rate: cost to S.J. plus 15%..$1.79/min (Iridium) - Baud rate (today): 2400 b/s (Iridium) - Apparently will be major increase in speed between now and fall
