Dataset description

This is the data for High-speed Imaging of Ice Nucleation in Water Proves the Existence of Active Sites, where we demonstrate that specific locations on the surface of feldspar and quartz are repeatedly the area in which ice growth originates in freezing experiments, i.e. the nucleation active sites. This means that heterogeneities on the surfaces are of first order importance in determining the temperature at which liquid water freezes. The data contained in this repository consists of the ice nucleation experimental data, used to construct the figures in the main text and supplementary materials. These show that nucleation is site specific for both quartz and feldspar. We also present WDS mapping results, where no chemical differences were found at the active sites within the resolution of the technique, leading to our hypothesis that topography is an important factor in determining ice nulceation effectiveness of a site.
