Abstract:
In this study we present dissolved and particulate silicon isotope results in surface waters obtained as part of the GEOTRACES central Arctic Ocean section GN04 (2015) onboard POLARSTERN cruise PS94 (ARK-XXIX/3).
The aim of the study was to investigate in more detail the influence of the Transpolar Drift on the Si cycle in the AO comparing areas with and without its influence.
