Virtual Goldschmidt 2020

June 21 - June 26

Goldschmidt is the foremost annual, international conference on geochemistry and related subjects, organized by the Geochemical Society and the European Association of Geochemistry.

GEOTRACES session:

14m: Biogeochemical Cycling of Trace Elements and their Isotopes in the Oceans (GEOTRACES)

Conveners: Tim Conway, Mariko Hatta, Nick Hawco

Keynote: Brandy Toner
Invited Speakers: Jun Nishioka, Sam Wilson

Trace elements and their isotopes (TEIs) play critical roles in ocean biogeochemistry and carbon cycling, as well as providing new insights into oceanic processes such as circulation, ventilation, particle scavenging, primary productivity, redox state and source/sink processes. In the last decade, the International GEOTRACES Program has facilitated rapid progress in this area, providing a wealth of data, answers and new questions for our understanding of past and present ocean TEI cycling. In this session, we aim to bring together studies from a range of disciplines, over a range of scales, that aim to address current questions in marine biogeochemical cycling. We invite submissions concerning any aspects of trace element chemistry and biogeochemistry in the oceans, and encourage submissions presenting process studies or making use of large-scale concentration distributions or modeling of TEIs or their isotopes to provide new insights. Given the Hawaiian location of Goldschmidt in 2020, and the recent sharp focus on the importance of East Pacific Rise and Loihi as TEI sources, we especially encourage submissions dealing with the biogeochemistry of both near and far-field hydrothermal activity. We also encourage studies which focus on rates, abiotic/biotic particle scavenging, trace-metal speciation, redox and isotope cycling, organic ligand metal interactions, and boundary exchange (redox, atmosphere, sediments, hydrothermal, rivers), or those that aim to use trace element isotope systems (e.g. Ba, Si, Zn, Cd, Cr, Ni) as redox or productivity paleoproxies.
