GEOTRACES session at AGU Fall Meeting 2021

Dear colleagues,

We would like to draw your attention to the following GEOTRACES session at AGU Fall Meeting 2021 (December 13-17, New Orleans, LA, and online everywhere

The deadline for abstract submission is August 4, 2021 (23:59 EDT/03:59 +1 GMT).

GEOTRACES session:

*PP024. Refinement of paleo-proxies in the GEOTRACES era

Co-conveners: Christopher Hayes, Kazuyo Tachikawa, Kassandra Costa and Jesse R Farmer.

Session Description:

Our knowledge of the past ocean relies upon measurable quantities in the sedimentary record that represent past conditions. The development of these proxies is driven by linking relationships between processes in the modern ocean and the transfer of signals into preserved archives, ranging from bulk sediment to species-specific fossils. The international GEOTRACES program has been surveying the global ocean distribution of trace elements and isotopes, many of which have specific paleoceanographic applications, including protactinium-thorium ratios and neodymium isotopes. Furthermore, the advancements GEOTRACES has made in the understanding of micronutrient metals, redox sensitive metals and nutrient isotopic ratios also have significant implications for our understanding of past ocean circulation, biological productivity, particle Kuxes and climate. In this session we welcome abstracts focusing on either modern or past ocean systems that speak to the development, calibration, or modeling of proxies and/or any associated updates to our proxy-based understanding of ocean conditions
