Spatial changes in gas transport and sediment stiffness influenced by regional stress: Observations from piezometer data along Vestnesa Ridge, eastern Fram Strait
Gas transport through sediments to the seabed and seepage occurs via advection through
pores, faults, and fractures, and as solubility driven gas diffusion. The pore pressure gradient …
