Project description:
This project focus on the optical and microphysical characterization of particulate matter (mineral dust, BC,...) contained in the seasonal snowpack. For this reason we want to continue the measurements of the particles in the lower atmosphere (OPTAER project) with the maintenance of the SPES instrumentation at the Gruvebadet laboratory. This is important to characterize the deposition of the particles on the snowpack and trace back significant deposition events. We also want to perform some measurements collecting snow samples and making stratigraphic profiles in snow pits in selected glaciers around Ny-Alesund such as: Broggerbreen, Edithbreen, Midtre Lovembreen, Austre Lovembreen and Kongsvegen. On these glaciers we also perform measurements with a snow-probe (SNOWLIGHT project) to detect the solar light penetration in the snowpack in different snow conditions. During these activities we need 2 snow mobiles and 1 sled of the Dirigibile Italia station. We plan 5 days in the field activities on the glaciers and 8 days in the Gruvebadet lab and snow field. To overcome the problems that probe measurements can only be conducted under clear or at most slightly cloudy sky conditions and that we need the highest snowpack, we planned to stay in the Dirigibile Italia Station for 21 days in the period between March and April. The researchers involved in this project and who will spend the indicated period at the station are 3: Marco Potenza as PI and expert in the SPES and Snow-Probe instrumentations and physical analysis, Claudio Artoni as expert in the snowpack physical properties and in field safety and Luca Teruzzi as expert in the operational and data analysis of the Snow-Probe and SPES instrumentation.
