High-resolution bathymetry data of the Witch Ground Basin (central North Sea) aquired during research cruise MSM63

Bathymetric data were acquired with the EM712 system mounted to the hull of RV Maria S. Merian (Figure 1). The survey was designed to provide high-resolution bathymetry with 5 x 5 m resolution. We processed the data using MB Systems software (Caress & Chayes, 2017) and included statistical evaluation of soundings that increased the signal-to-noise ratio. The sound velocity profile for multibeam processing was measured at the beginning and at the end of the cruise.
