Purpose
Abstract SO193 aimed to reconstruct the origin and spatial and temporal evolution of the Manihiki Plateau and to characterize the relationship between the Manihiki Plateau and other LIPs in the western and southwestern Pacific. The accuracy of the EM20 data that was obtained is usually critically dependent upon weather conditions and the use of a correct sound speed profile. During SO193 two sound profiles have been recorded at different stations. Thus, the correct sound velocity was used in the different geographical areas on this cruise
