Trace Elements in Arctic Ocean Aerosols: Contemporary Status and Decadal Variability
This study presents extensive shipboard observations of 13 aerosol trace elements across the Arctic Ocean during summer 2024. TE concentrations and the enrichment levels of anthropogenic TEs rank among the lowest globally observed. Decadal comparisons revealed a near ten-fold reduction in Pb and Cd enrichment, contrasting with a near-doubling of V enrichment driven by intensified Arctic shipping.
