Resumen
Oceanographic research vessels are platforms to carry out acoustic surveys to assess pelagic fisheries resources, using scientific echosounders like Simrad EK60. The quantitative use of echosounder’s data requires a precise determination of background noise since a good signal to noise ratio (SNR) is determinant to have an accurate estimation of fishery resources.
This paper presents a new systematical analysis of noise test results method. Three different research vessels (R/V) have been analyzed proving that only 18 and 38 kHz frequencies are influenced for vessel’s propeller system.
