Table 2. Hydrophone array characteristics and dates used during SWFSC research cruises. Hydrophones with a “*” included a
single high-frequency hydrophone with a flat frequency range from 1 kHz to 150 kHz ( ± 2 dB at -166 dB re 1 V/mPa) in addition
to the other elements listed. The ‘SW Norris’ and ‘SE Norris’ arrays were built by Don Norris of Sonatech, Inc. Due to a design
problem, only four of the five hydrophone elements on the SW Norris and SE Norris arrays were operational (shown in
parentheses).
