Supplementary material from "Annual cycle of downward particle fluxes on each side of the Gakkel Ridge in the central Arctic Ocean"
Two mooring arrays carrying sediment traps were deployed from September 2011 to August 2012 at ~83°N on each side of the Gakkel Ridge in the Nansen and Amundsen Basins to measure downward particle flux below the euphotic zone (approx. 250 m) and approximately 150 m above seafloor at approximately 35...
