    U-Series isotopes analytical results (U & Th) on core PS2757-6 (MUC) (2021)
    PANGAEA
    Details
    Publication Date: 2023-01-30
    Description: Core PS2757-6 was retrieved with a multicorer (MUC) on the Lomonosov Ridge next to the Russian continental shelf during the Polarstern expedition ARK-XI/1 in 1995. This expedition had the principal aim to study material fluxes and ecological connections between the Arctic Deep Basins and the adjacent Siberian shelf seas, the northern Laptev Sea and the northeastern Kara Sea. In 2018 and 2019, this core had samples analyzed by MC-ICPMS at the Geotop-UQAM laboratories for uranium-series isotopes with the aim to establish radiochronological age constraints for the coring location.

    Carbon isotopes composition of otoliths from surface samples of the Lomonosov Ridge, Arctic Ocean (2022)
    PANGAEA
    Details
    Publication Date: 2023-06-27
    Description: 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.
