Seismic data (ARA05C-L05 and L17 lines, segy format) and related inverted models (binary files) for Imaging the P-wave velocity structure of Arctic subsea permafrost
The multichannel seismic (MCS) survey was conducted on the outer continental shelf and slope of the Beaufort Sea, the Arctic Ocean from 2nd to 13th September 2014, and the main objective of the survey is to investigate sedimentary stratigraphy, locations of permafrost. Presented inverted P-wave velocity models were calculated by the Laplace domain full-waveform inversion method from the acquired seismic dataset. It uses to image the subsea permafrost on the continental shelf of the Canadian Beaufort Sea by interpretation.
