Shallow and Deep Seismic Amplitude Anomalies Indicate Times of Fluid Accumulation and Tectonic Activity in the Barents Sea
This master thesis studied the 3D-seismic dataset ST0825 located in the southwest Barents Sea. Aiming to map seismic anomalies and faults above and below the Upper Regional Unconformity (URU). The survey partly covers four different structural elements: Finnmark Platform, Tromsø Finnmark Fault Compl...
