Abstract:
The magnetotelluric impedance tensor elements and errors were calculated with the software BIRRP (Chave &Thomson, 2004; doi:10.1111/j.1365-246X.2004.02203.x). Magnetotelluric measurements were conducted from December 2010 to January 2011 at the Walvis Ridge, offshore Namibia. Coordinates of the MT stations are included in the EDI files and cover an area at ~8°E - 12°E, ~18°S-22°S. Station deployment and recovery was conducted on the two cruises MSM17/1 and MSM17/2 on German research vessel Maria S. Merian as part of the SPP1375 priority program SAMPLE. The SAMPLE project focused on the processes linked to continental margin formation.
