Dataset S1 is uploaded with file name Dataset S1-Stress-Strain Data. xlsx. Detailed information includes Deviator stress versus axial strain for hydrate-bearing sediment specimen (Figure 8) Dataset S2 is uploaded with file name Dataset S2-Total hydrate number, volume, diameter, sphericity-Strain. xlsx. Detailed information include Variation in the total hydrates, average volume, average equivalent diameter and average sphericity of hydrates along with axial strain. Data are used to generate Figure 12 & 13 in this manuscript. Dataset S3 is uploaded with file name Dataset S3-Sphericity- Cumulative percentage Data. xlsx. Detailed information include Variation in the sphericity of the hydrate particles along with the cumulative percentage at different axial strains. Data are used to generate Figure 14 in this manuscript. Movie S1 is uploaded with file name Movie S1. gif.
