Marine magnetic data of profile SO305/2_9-3 over the Argo transform fault at the Central Indian Ocean near 13°30'S during SONNE cruise SO305/2

During the cruise SO305/2 of the German research vessel SONNE, we recorded densely spaced magnetic field measurement over the Argo transform fault offsetting the Central Indian Ridge near 13°30'S. The total magnetic field was measured using two SeaSpy magnetometers which were towed at 500 m and 575 m, respectively, behind the stern of the ship, sampling the data continuously at 1 Hz. The ships navigation was corrected to match the position of the sensors towed behind the vessel and data were resampled at 30 s. Uncorrected total field magnetic data are available in text/ascii format.
