Session description:
The compositions of seawater and marine particulate material, and their temporal and spatial fluxes and exchange, play a pivotal role in modulating the biological pump and atmospheric CO2 uptake, as well as various biogeochemical processes in the oceans. Determination of the inputs, settling fluxes, remineralization rates, chemical scavenging and the linkage of particles to seawater composition and marine productivity, are therefore critical for a full understanding of marine biogeochemical cycles and their impact on global climate.

Here we seek contributions on the following non-exclusive topics: (1) new methodologies for determination of trace element concentrations, isotopic compositions, or particle flux rates, (2) new approaches to characterize particle compositions, including across size classes, mineralogical phases or different environments, or (3) the interactions between particles and dissolved distributions. We encourage submissions of multi-disciplinary studies, such as GEOTRACES or other programs, including applications of radionuclides, experimental and analytical isotope geochemistry, modeling, and trace element partitioning between solid, colloidal and dissolved phases. We focus on studies that describe processes in the modern oceans but submissions discussing paleoceanographic conditions are welcome. We further seek studies that focus on the interplay between external sources (e.g., dust, rivers, margins), surface productivity and marine particulate and dissolved compositions and fluxes.
