Gridded bathymetry from EM120 multibeam echosounder of R/V Maria S. Merian cruise MSM4/4a
Bathymetry data was acquired during R/V MARIA S. MERIAN cruise MSM4/4a in the Atlantic North West off Africa between 27.02.2007 and 16.03.2007. The cruise focused on the study of particle transport processes as well as the collection of sediments for the reconstruction of past environmental conditio...
