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.

Warming the Arctic surface ocean due to influx of warm Pacific water not only leads to the declining of the sea ice extent but also triggers melting gas hydrate stored in the Arctic Sea floor of the continental shelf areas. Methane (CH4) is the most abundant hydrocarbon in the atmosphere, where it plays a much more effective role as the greenhouse gas than carbon dioxide (CO2). To understand the behavior of gas hydrate in the sediment and to estimate the CH4 fluxes from the sediment through the water column to the atmosphere, we obtained data on water temperature, salinity, density and fluorescence in the water column.
