2011 Grímsvötn eruption: table of ash shape parameters

Dataset

Description

This dataset contains raw size measurements and derived shape parameters for six ash samples of the 2011 Grímsvötn eruption, Iceland (G1, G3, G4, G6, G7, & G8). All size measurements were made on backscattered electron SEM images using ImageJ image analysis software. Size measurements have units of pixels, and the dimensions of each pixels (in microns) is given for each sample. This dataset forms part of the supplementary material for the publication Liu, E.J., Cashman, K.V., Rust, A.C., & Gislason, S., (2015), The role of bubbles in generating fine ash during hydromagmatic eruptions', Geology.
