The relationship between boatwhistle parameters (e.g., PRR, duration) and male reproductive success needs further investigation; however, the recent development of a hydrophone array that can localize toadfish nest sites (Putland et al., 2018) might allow correlation of vocalization with reproductive success (i.e., eggs in nest).
Figure 1(b) shows a schematic of the fabricated diaphragm hydrophone array with 8 x 8 elements.
Mobile positioning of tagged aquatic animals using acoustic telemetry with a synthetic hydrophone array (SYNAPS: Synthetic Aperture Positioning System).
The ship being measured will pass by the hydrophone at controlled conditions and speed at least 100 meters from the hydrophone array. The measured sound at the hydrophone is then adjusted based on the actual distance between the ship and hydrophone.
It consists of two SAS systems: a high frequency (HF) synthetic aperture sonar and a long-wavelength broadband (BB) synthetic aperture sonar, wherein two separate projectors share a common hydrophone array, as shown in Figure 1.
Deirdre Slevin, who was with the group, said the RV Celtic Mist carried a towed hydrophone array for acoustic detections and surveyed offshore shelf edge waters as well as inshore and coastal waters to provide the maximum variety of species and marine habitats.
Early each morning, in the base's onshore acoustics room, researchers began by identifying where whales were located within the hydrophone array. The rectangular-shaped array, broadcast on computer monitors, showed colored lights representing each hydrophone.
Acoustic signals generated by pipeline leaks are detected by a system composed of a hydrophone array, a preamplifier and a cable driver.
That day, the hydrophone array picked up distinctive earthquake tremors caused by magma moving upward through the crust.
As part of the experiment, WHOI researchers Keith von der Heydt and John Kemp designed and deployed an autonomous hydrophone array that recorded the longest, highest-quality shallow-water acoustics data set ever collected.
The last eruptions from both were recorded using seismometers as well as hydrophone arrays.
