Geochemical compositions of cryptotephra particles analysed from the RICE (black squares) and SPC14 (cyan squares) ice cores compared to four cryptotephra layers identified by Di Roberto et al.52 in a marine sediment core collected in the Edisto Inlet, Ross Sea. They include the TR17-08–56 cryptotephra (red diamonds) produced by a historic eruption of Mt. Rittmann at 1254 CE, and three additional cryptotephra layers from Mt. Melbourne at 335 CE (TR17-08–512: green diamonds), 302 CE (TR17-08–518: blue diamonds), and 273 CE (TR17-08–524: pink diamonds)52. Note the individual measurements (open squares) and mean value (filled squares) from polished EMPA-WDS of glass shards identified in our samples of the RICE and SPC14 ice cores.
