Abstract:
Fossil fish otoliths were collected in surface sediments (0 to 1 cm) from the Lomonosov Ridge, Arctic Ocean, recovered with a giant box corer during the R/V Polarstern Expedition PS87 of 2014. Carbon isotopic measurements of 22 specimens were performed in 2022, at the 14C laboratory of the Alfred Wegener Institute Helmholtz Centre for Polar and Marine Research, Germany, with a MICADAS-mini carbon dating system. Results show a wide range of 14C-ages from ~44 to 0.4 ka, illustrating the mixing of late Quaternary fossils at the sediment surface in low sedimentation rate sites of the Arctic Ocean. Significant δ13C-values differences could be identified between pelagic and benthic fish, in accordance with their distinct habitats.
