Abstract:
During the MSM130 research cruise with the German research vessel Maria S. Merian in July and August 2024, sediment samples were collected using a minituarized multicorer (Mini-MUC) at 12 stations across three fjords in SE Greenland: Sermilik, Sikuijvitteq and Kangerlussuatsiaq. The MUC cores were sliced into 1 cm segments from 1-4 cm sediment depth, 2 cm segments from 4-10 cm, and 3 cm segments below (to a maximum depth of 25 cm). Pore-water analyses were conducted for dissolved iron (dFe), dissolved manganese (dMn), sulfate (SO42-), sulfide (H2S), silicate (SiO2), phosphate (PO4³-), ammonium (NH4+), anddissolved inorganic carbon (DIC).
