Abstract
Here we make available raw data and code used in the paper, "Trapped bubbles keep pumice afloat and gas diffusion makes pumice sink" by Fauria, Manga, and Wei (2017, EPSL). Included in this database is:
1. A .pdf copy of Fauria et al. (2017).
2. Trapped bubble and vesicle volume and surface area measurements from six uXRT samples (Data3.mat and TrappedGas_VolumeArea.xlsx) and a corresponding readme file.
3. Script to plot bubble and vesicle size distributions, power-law fits, and surface area-to-volume fits (i.e., Figures 4, 5, and S2). This script (PlotBubbleSizeDist3.m) references code from Clauset et al. (2009) (i.e., plfit.m and plplot.m) and that can be downloaded here: http://tuvalu.santafe.edu/~aaronc/powerlaws/.
4. Script to plot Figure 6 from the text (PumiceFloatation_August2016.m). This script also includes floatation time measurements from this study and others that are referenced in Fauria et al. (2017).
5. A movie (SMK2_6_small) that shows a 3-D rendering of our X-ray tomography measurements. In the movie, the light blue represents the pumice rock and the bright colors represent trapped gas bubbles- where the different colors are used to show separate bubbles. The aqua color present in the last 8 seconds of the movie represents liquid phase.
