Particles (> 500 nm) in ice cores

Climatic indications of particles (>500nm) in Ice cores

Particles trapped in the Antarctic ice shield contain a lot of climatic information. Researchers have studied the chemistry of individual particle in great detail, which however dramatically reduced the amount of analyzed particles, as the analysis was always performed manually. A large number of particles can be processed by particle counters, producing a solid dataset on the particle size distribution, but with the drawback, that the chemical composition of the particles remains unknown. In this study we tried to combine the advantages of both approaches by using CCSEM (computer controlled scanning electron microscopy).
