Thorium isotopes in the water column in Amundsen Basin during POLARSTERN cruises PS70 (ARK-XXII/2) in 2007 and PS94 (ARK-XXIX/3) in 2015 ...
In this study we present dissolved ²³⁰Th and ²³²Th results, as well as amount of particulate ²³⁴Th from total ²³⁴Th. The data, obtained as part of the GEOTRACES central Arctic Ocean sections GN04 (2015) and IPY11 (2007). Samples were analyzed following GEOTRACES methods, and compared to previous res...
