    Characterization of insoluble nanoparticles in Antarctic ice cores
    (American Geophysical Union, 2013-12-09) Ellis, A; Edwards, R; van Riessen, A; Saunders, M; Smith, AM; Curran, MAJ; Goodwin, ID; Feiteng, W
    Insoluble nanoparticles in the form of aerosols have significant effects on climate and biogeochemical cycles. Records of these aerosols are essential for understanding paleoclimate forcing and future climate change. These particles and their precursors are emitted to the atmosphere from a variety of primary and secondary sources including biomass burning as well as biogenic, anthropogenic, volcanic, extraterrestrial, and terrestrial mineral emissions. While a large body of research exists with respect to mineral dust particles (on the micrometer scale) derived from ice and sediment cores, very little is known with regards to the history of insoluble particles on the nano scale. Ice core records are the only reliable way to study the past history of these particles. Here, we will present new data regarding the physical and chemical properties of nanoparticles found in ice cores from East Antarctica.

    Characterization of insoluble nanoparticles in ice cores from Law Dome, East Antarctica

    Insoluble nanoparticles, in the form of aerosols, have significant affects on climate and biogeochemical cycles.

Ice core records are the only reliable way to study the past history of these particles. Here, we will present new data with regards to the physical and chemical properties of these particles as found in the Law Dome ice core, DSS0506 from East Antarctica.
