Fig. 4: Crater thickness map between crater floor horizons CF1 and CF2.
From: Multiple lines of evidence for a hypervelocity impact origin for the Silverpit Crater
Contour increment is 10 m. The map shows a clear change in thickness between the central, nested inner crater (~60 m), the wider crater up to the crater rim (~15–30 m) and the crater brim (<10 m). The lack of contours in the PGS SNS 3D MegaMerge data highlights the increased frequency and lower tuning thickness of the Greater NEP 3D data.
