Granulometric data of pyroclastic fragments found at Livingston Island and Bransfield Strait (Antarctica)

Original granulometric data obtained using a laser diffraction particle analyzer (Coulter LS230) at the Departament de Dinàmica de la Terra i de l'Oceà at the University of Barcelona. Data were separated into two Excel files for each research: (1) granulometric data from tephra fragments of the 1970 eruption of Deception Island, and (2) granulometric data from tephra layers found in sediment marine cores at the Bransfiel Strait. These files are part of the Supplementary Material of the Doctoral Thesis: "POST-CALDERA VOLCANISM OF DECEPTION ISLAND (ANTARCTICA): NEW INSIGHTS FROM TEPHRA STUDIES AND PORT FOSTER BAY VOLCANIC DEPOSITS"
