Exact Expressions

We added a sediment layer with a Vp of 1.6 km/s, a Vs of 0.2 km/s, and a thickness of 0.4 km (e.g., Kanazawa et al. 2001; Shinohara et al. 2008) above the velocity model (Fig. 8a).

In the case of S waves with an employed frequency range of 2 5 Hz and a Vs of 0.2 km/s (Tonegawa et al. 2013), the wavelength becomes 40 100 m, indicating that estimation of Vp/Vs within marine sediments can be performed with mostly comparable wavelengths between P and S waves.

The velocity model was the same as the one in Fig. 7a but with a grid spacing of 0.04 km and a Vs of 0.9 km/s at the top layer, which ensured good calculation accuracy with 22 grids per minimum wavelength.

Considering the 4.8 × 106 tons of wet banana stem produced in Hainan province and chopped to a particle size of 20 mm having a VS of 3.78 % w/w and a BMP of 347 m3 ton−1 VS, the yearly methane production could sum up to 6.29 × 107 m3 CH4.
