This chapter presents a general overview of the major controls of trace metals in seawater, developed from the extensive research on trace metals over the last few decades. The reader should be given a first-order understanding and insight into trace metal biogeochemistry in the oceans, rather than presented with a comprehensive review of the distribution of each trace metal. Each of the trace metals discussed will undoubtedly prove to have unique characteristics and subtle differences from this version, yet the comparison with these characteristics will serve as a good springboard to a more complete understanding.read more

Mercury biogeochemical cycling in the ocean and policy implications.

TL;DR: This analysis suggests that while atmospheric deposition is the main source of inorganic Hg to open ocean systems, most of the CH₃Hg accumulating in ocean fish is derived from in situ production within the upper waters (<1000 m), and that the deeper waters of the oceans are responding slowly to changes in atmospheric Hg inputs.

The Trace Metal Composition of Marine Phytoplankton
TL;DR: There are notable differences between taxa and regions that inform the understanding of ocean metal biogeochemistry, and differences in the quotas estimated by the various techniques also provide information on metal behavior.

Chapter Fourteen Elemental Proxies for Palaeoclimatic and Palaeoceanographic Variability in Marine Sediments: Interpretation and Application
TL;DR: In this article, the elemental proxies for palaeoclimatic and palaeoceanographic variability in marine sediments are discussed, and the application of sedimentary geochemistry to the reconstruction of climatic and oceanographic changes over the Cenozoic is discussed.

Feedback Interactions between Trace Metal Nutrients and Phytoplankton in the Ocean.
TL;DR: Iron is thought to play a key role in regulating biological cycles of carbon and nitrogen in the ocean, including the biological transfer of carbon to the deep sea, the so-called biological CO2 pump, which helps regulate atmospheric CO2 and CO2-linked global warming.
Journal ArticleDOI
The Isotope Geochemistry of Zinc and Copper
TL;DR: Chaboy et al. as mentioned in this paper showed that the symmetry of the hexaaqua complex of Cu(H2O)62+ has a Jahn-Teller distortion effect (Sherman 2001; Bersuker 2006), whereby the two Cu-O distances of the vertical axial bond (Cu-Oax) are longer than four Cu O distances in the equatorial plane (Cu Oax).

TL;DR: The iron cycle, in which iron-containing soil dust is transported from land through the atmosphere to the oceans, affecting ocean biogeochemistry and hence having feedback effects on climate and dust production, is reviewed.

TL;DR: It is demonstrated that iron supply controls phytoplankton growth and community composition during summer in these polar Southern Ocean waters, but the fate of algal carbon remains unknown and depends on the interplay between the processes controlling export, remineralisation and timescales of water mass subduction.
