Abstract:
For the past 20 years, the GEOTRACES program has produced transformative insights into the cycling of trace elements and isotopes (TEIs) in the ocean. Modeled after the 1970s GEOSECS (Geochemical Ocean Sections Study) program, the goals of this ambitious study were to conduct large-scale measurements of TEI concentrations and to determine the biogeochemical processes that controlled their distributions throughout the global ocean. Perhaps the biggest hurdle to overcome was how to accurately measure less than nanomolar concentrations of TEIs from the deck of a 3,000 gross tonnage steel ship. Co

Abstract:
Between 40 % and 50 % of the Earth’s primary production occurs in marine environments, primarily by phytoplankton. The trace metal micronutrients iron, zinc and cobalt are known to exert a significant biological control on phytoplankton productivity by serving as essential active centres in enzymatic processes such as inorganic carbon, nitrogen and phosphorus acquisition. The distributions and biogeochemistries of iron, zinc and cobalt therefore, have the potential to impact upon the global carbon cycle and hence climate.

Fixed N (nitrate, nitrite, and ammonium) is a limiting nutrient for photosynthesis in the surface ocean. The rates and relative importance of N cycling processes, however, are temporally and spatially complex, which hamper their direct measurement and quantification.

Abstract:
Marine phytoplankton account for more than 40% of global primary production and hence play an important role in moderating global climate through ocean-atmosphere CO2 exchange. Zinc (Zn) is an essential micronutrient and plays an important role in the carbon acquisition system within marine phytoplankton, thus, it has the potential to influence marine primary production. In seawater, Zn bioavailability is dependent on its concentration and its chemical speciation. The free Zn2+ ion concentration of the surface ocean is usually in the low picomolar range
