There were at total of 427 analyses of samples obtained from the field, the collections of the USGS Hawaiian Volcano Observatory (HVO), the University of Hawai\u02bbi, and the Smithsonian Institution. The samples originated from K\u012blauea (historical and prehistoric summit and rift zone lavas), Mauna Loa (historical lavas), and L\u014d\u02bbihi (submarine lavas of unknown age). Data for associated reference materials are described in the process steps. The Sr isotope ratios may be used to test models for the magmatic plumbing system of each volcano.
