Fig. 3: Crater surface morphology and seismic attributes of horizons CF1 and CF2 at the crater floor.
From: Multiple lines of evidence for a hypervelocity impact origin for the Silverpit Crater
True vertical depth subsea (TVDSS) structure maps with a 25 m contour interval (a, d), RMS amplitude (b, e) and dip (c, f) attributes for the CF1 (upper row) and CF2 (middle row) horizons, respectively. Seismic sections show the detailed crater morphology across the ~3.2 km central crater, including the ~1.2 km wide nested inner crater above the central uplift (g) and ~50–150 m diameter secondary craters beyond the crater rim (h). Note the high seismic amplitudes extending around 1.5 km from the crater rim in (b) and (e).
