摘要：Measurements of cosmic-ray nucleon and meson components were carried out on the on the southbound voyage were almost the same as those obtained on the northbound ice-breaker " SoY A " throughout the full trip. voyage. Latitude effects of 60'.? for the nucleon component and 12'.? for the meson component were obtained. The knee of the latitude curve was found at about the same geomagnetic latitude 35 S for both components. North-south asymmetry can be explained by assuming the cosmic-ray coordinates shifted westward by 45° from the centre dipole field.
