The present dataset contains results from magnetic data measurements – data files and plots –on sediment cores collected during the M162 marine campaign, conducted onboard the R/V Meteor (Geomar, Germany) from 06/03/2020 to 11/04/2020 along the Gloria Fault - the Atlantic plate boundary between the Africa and the Eurasia plates. 46 gravity cores (39 with successful recovery) were collected on 6 geographically defined working areas (WA1 to WA6), from the Azores plateau to the Josephine seamount area. Magnetic susceptibility was measured onboard after core opening, using a KT10 magnetic hand susceptibilimeter (Bartington). Generally, one measurement was taken at each 5 cm, except when the core was very monotonous (each 10 cm) or when singular sedimentary horizons occurred in between each 5 cm mark. In addition to onboard measurements, 26 cores were also sampled using 2×2 cm3 plastic boxes, standard for laboratory magnetic analysis. Magnetic measurements were later conducted on the Paleomagnetism Laboratory of Instituto Dom Luiz (FCUL, Lisbon, Portugal), and included: anisotropy of magnetic susceptibility (AMS), using a MFK1 Kappabridge (Agico), natural remanent magnetization (NRM) using a JR6 spinner magnetometer (Agico), and its alternating field demagnetization, using a LDA-3 AF demagnetizer (Agico).
