Evaluation of the oceanographic measurement accuracy of different commercial sensors to be used on fishing gears

Summarizing, the data collected by Star-Oddi sensors are useful only considering the data portion where a dwell time at a fixed depth permanence is longer than 50 s, while those collected by NKE sensors are much more accurate for both depth and temperature and could be usefully considered for broader oceanographic purposes. The weak point of the NKE sensors is the salinity measurement. The evaluation carried out in the present study underlined the optimal conditions for the usage of the considered sensors and produced a series of offsets that might be used to enhance the accuracy of the recorded datasets.
