Twenty Years of GEOTRACES

June 05, 2024

  A special issue of Oceanography celebrates 20 years of the international GEOTRACES program. The issue highlights the advances accomplished during the program,  and its impact on our understanding of processes that determine the oceanic distributions of trace elements and isotopes (TEIs).
