Description 156-163
The
spatial variability of sediment geoacoustic inversion results, derived from
dual-frequency single-beam (SBES) and multi-beam echosounder system (MBES)
operable at 33/210 kHz and 95 kHz, respectively, have been analyzed to
demonstrate the interrelationship among the sediment texture and benthic
macro-fauna abundance. The correlationship among the derived acoustical and
biological parameters was identified from the spatial map generated using
ArcGIS and validated by applying Principal
component analyses (PCA). Distinct interclass separation of the sediment
provinces is revealed by the spatial variability in the computed inversion results,
demonstrating a strong correlation with the backscatter and biologically active
faunal functional group assemblages on the seafloor. The results obtained are
indicative of bioturbation by benthic animals, resulting in variability in the
data that should be taken into account to optimize the model-data matching
procedure during inversion.
