This dataset supports the thesis entitled "Imaging the Internal Structure of an Active Fluid Escape Structure in the North Sea: 3-D Full Waveform Inversion of the Scanner Pockmark OBS Seismic Dataset"

AWARDED BY: Univeristy of Southampton

DATE OF AWARD: 2025

DESCRIPTION OF THE DATA:
- List of P-wave velocity (Vp) models derived from seismic data acquired over the Scanner Pockmark (SP) complex. The models were generated using full waveform inversion (FWI) approaches using the in-house software tools provided by Shell and Imperial Collegeand a Tomographic model (Tomo) using the open-source FAST tomography code. The FWI velocity models are in both binary and SEG-Y, while the Tomo velocity model is only in binary format.
