Accompanying dataset for thesis: Volatile metal degassing from volcanoes: source processes, atmospheric transport and deposition. Full details of data uses are given in the thesis document, which is open access and linked to this dataset. The dataset contains folders labelled by the chapter of the thesis they correspond to. On the first sheet of each excel file contained in this dataset there is a full description of what the data is, and where it is used in the thesis.

Chapter 2: Data to support Methodology Chapter 3: Villarrica 2018 gas composition, including chemical speciation modelling and a global review of metal emissions from volcanoes (this chapter also includes a review of metal melt inclusion compositions, including new melt inclusion compositions from Villarrica and Mt Etna) Chapter 4: Kilauea 2018 gas composition, and composition of the lava ocean entry plume. Chapter 5: Composition of the downwind atmosphere of Hawai'i during the 2018 eruption of Kilauea volcano Chapter 6: Review implications of ice core record of volcanic metals from the 17.7 Mt. Takahe in Antarctica.

This dataset contains gas and aerosol compositions (with a particular focus on volatile metals) of volcanic gases collected using filter packs and size-segregating cascade impactors at Kilauea Volcano, Hawai'i, and Villarrica, Chile. It also contains downwind compositions of the atmosphere around the Island of Hawai'i during the 2018 eruption of Kilauea. Further, it contains chemical speciation modelling (modelled using HSC Chemistry) of volcanic gas emissions and a review of the global database of volatile metal emissions from volcanoes.

The purpose of this dataset is to support the thesis of the same name: Volatile metal degassing from volcanoes: source processes, atmospheric transport and deposition. The aim of this thesis is to further our understanding of the behaviour of volcanic volatile metals as they are emitted from volcanoes, and during atmospheric transport.
