Bioactive trace metals and their isotopes as paleoproductivity proxies: An assessment using GEOTRACES-era data

This contribution grew (and grew) out of a joint workshop between GEOTRACES and Past Global Changes (PAGES) held in Aix-en-Provence in December 2018. The workshop was funded by the US National Science Foundation (NSF) through the GEOTRACES program, the international PAGES project, which in turn received support from the Swiss Academy of Sciences and NSF, and the French national program LEFE (Les Enveloppes Fluides et l'Environment). The authors extend tremendous thanks to the GEOTRACES-PAGES workshop organizers, particularly Bob Anderson, Catherine Jeandel, Laurence Vidal, and Kazuyo Tachikawa.
