Midwater Multi-beam Sonar Data Analysis Techniques for Fisheries Applications
The recently developed multi-beam underwater sonar technologies
offer new opportunities for fisheries applications. In this
project, conducted in conjunction with the Sonardata company,
sonar modelling techniques have been developed to convert
raw multi-beam sonar data into midwater soundings. A sounding
is a measurement of the sonar backscatter occuring at a specified
point in space in a particular instant of time. Work is now
progressing to convert these soundings into data values which
can directly indicate the presence of fish schools, determine
the species of fish and estimate the overall biomass contained
in the school.
