Abstract:
In this study we present dissolved and particulate silicon isotope results from intermediate to deep 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 the relative influence of water mass mixing and particle flux on the Si cycle in the Arctic Ocean.
