U-Series isotopes analytical results (U & Th) on core PS2757-6 (MUC) ...

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 adjacen...

Description
Summary: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. ...
