Methane bubble rise velocities in artificial seawater and demineralized water under deep-sea and ambient conditions

Single methane bubbles are recorded under different pressure/temperature conditions to investigate the influence of pressure and artificial seawater on the bubble rise velocity. Therefore two similar experimental setups in the lab-scale are used, one for high-pressure applications and one for ambient conditions. For the generation of the bubbles in both setups the same capillaries are used. The gas phase is pure methane and the liquid phase (continuous phase) is artificial seawater as well as demineralized water (DI-water). The velocities at 4 °C and 20 °C and pressures of 0.2 and 15.1 MPa are compared. This dataset is an expansion of the results published in the dataset R1.x135.118:002 (DOI: 10.7266/N75M63N6).
