Analysing estimators in the alternative echo integrator method
Aksland, Magnar (Peer reviewed; Journal article, 2010)Abstract: New and existing estimators of the “Echo Value Constant” based on split-beam detected and integrated single target echoes in the “alternative echo integration method” have been compared by using acoustic data. ... -
Estimating Fish Densities from Single Fish Echo Traces
Aksland, Magnar (Peer reviewed; Journal article, 2009)Estimating mean fish density per unit area has been done by counting single fish echo traces with a split beam echo sounder system in the open sea. A data program has been written that scans the acoustic signals for echo ...
