©2020 Biological and Chemical Oceanography Data Management Office.This is a dataset of arctic aerosol Be7 concentrations from the MOSAIC expedition on the R/V Polarstern in the Central Arctic Ocean from December 2019 to June 2020.
Aerosol samples were obtained with a Tisch TE-5170V-BL high volume aerosol sampler, modified to collect 12 replicate samples on acid-washed 47mm diameter Whatman-41 (W-41) filters, using procedures of the US GEOTRACES aerosol program (Morton et al., 2013; Marsay et al., 2018). The aerosol sampler was mounted on the Polarstern p-deck.
For 7Be, three of the 47mm aerosol samples were stacked in a plastic Petri dish and counted by gamma spectroscopy. Be-7 has a readily identifiable gamma peak at 478 keV. The counting system was calibrated for all samples by preparing a commercial standard in geometry identical to the samples.
