The data contain processed multichannel seismic data from the Namibia continental slope. Multichannel seismic data was acquired on R/V Meteor expedition M49/1 and on R/V Maria S. Merian expedition MSM19/1c using the high-resolution seismic acquisition system of the Department of Geosciences at the University of Bremen, Germany. During cruise M49/1, two Sercel GI-Guns were employed alternatingly, one with 2 x 1.7 L volume and another with 2 x 0.4 L chamber volume. The Syntron streamer used for recording consisted of a 600 m active section with 48 channels at 12.5 m spacing. During cruise MSM19/1c, the multichannel seismic data was acquired using a Sercel GI-Gun with a chamber volume of 2 x 1.7 L as seismic source.
