Penguin Banks Acoustic Bottomfish Survey (SE0703L2, EK60)
Narrow-band, split-beam acoustic data were collected using a Simrad EK60 system operating
at 38 and 120 kHz frequencies along predetermined transects to collect reverberation
data from organisms in the watercolumn to be processed for echoes of economically
important bottomfish.

Purpose | The scientific objective of this cruise is to assess the feasibility of separating acoustic signals of economically important Hawaii semi-demersal fish from other signals using narrow-beam active acoustics and whether a methodology could be developed to estimate the abundance and biomass of these fish for stock assessment purposes. |
