Vapor Film Lifetime at Magma-Water Interface

Video records of the meta-stable vapor film conditions on a spherical magma sample in contact with water.

The dataset is the base the following article:
Experimental constraints on the stability and oscillation of water vapor film–a precursor for phreatomagmatic and explosive submarine eruptions. By I. Sonder, and P. Moitra, 2022 in Frontiers in Earth Science, 10, doi: 10.3389/feart.2022.983112 .

The dataset consists of observations (videos) of three experiments, and manually drawn polygons outlining the vapor film on the melt sample, or areas of direct magma-water contact.

• Video material is stored in two formats: (a) as video file (.mp4) and (b) as zip container that contains each of the video's frames in .jpg format.
• The polygon markup is stored in JSON format.

Changes

• Version 0.1:
  Initial upload of video and polygonal markup material.
