The importance of zinc may extend even further as the processes that control carbon uptake by marine phytoplankton are important in the carbon cycle, and the zinc enzyme carbonic anhydrase could be a limiting factor. The concentration of zinc available to some marine phytoplankton has... 

In recent years, there has been an increasing level of interest in the use of 234Th/238U disequilibrium in the marine environment to study geochemical processes with short time scales (up to 100 days), particularly those associated with carbon cycling in the oceans [34-36] and the partitioning of pollutants between the dissolved and particulate phases [37,38]. However, the analysis of 234thorium is constrained by its short half-life and its low concentration in seawater, so appropriate analytical techniques must be rapid and sensitive and preferably should allow shipboard analysis.

Measurement of trace metal concentrations can provide fundamental insights into marine geochemical processes. Many metals are important micronutrients in seawater and can play a significant role in upper ocean biogeochemistry and carbon cycling. Under certain conditions, elevated concentrations of metals associated with human activities can have negative impacts on marine ecosystems.
