dc.description.abstract | Calibration of fisheries echo sounders and integrators by means of optimal copper spheres is
reviewed. The standard procedure is elaborated. Maintenance of O.1 dB precision is described for a
wide range of temperatures and for untuned equipment. The method is illustrated by reference to a
calibration exercise of R/V "Michael Sars". The long-term stability of quoted, cumulative
calibration results for the same vessel witnesses to the reliability and precision of the method. | en |
