The 3rd GEOTRACES Data-Model Synergy Workshop will focus on ocean particles, with emphasis on their role in the biogeochemical cycle of trace elements & isotopes (TEIs). The exchange with particulate phases is recognized as an important process in the oceanic budget of a large number of substances present in trace amount in seawater, including that of key substances of GEOTRACES. Particles occur in variable amounts in different oceanic environments, such as the continental shelves and slopes, the bottom and intermediate nepheloid layers, and the particle-poor regions of the deep sea. Likewise, marine particles can occur with very distinct physical properties and chemical compositions. They are subject to a wide variety of processes, such as aggregation, disaggregation, precipitation, dissolution, sinking, and transport by currents. Moreover, the exchange of chemical constituents between the dissolved phase and particles can take different forms, including adsorption, desorption, (in)organic complexation, and biologically-mediated uptake and remineralization. In spite of the recognized importance of particles in the transport of trace elements in the ocean, various aspects of ocean particles remain poorly understood, such as the spatial variations in their concentration, chemical composition, and size distribution. This state of affairs implies that the current ability to constrain the representation of particles in models of ocean biogeochemistry is limited.

The goal of the workshop is to bring together analysts and modelers in an effort to answer to two specific questions:

What measurements of particles should GEOTRACES make?

2)How should models of ocean biogeochemistry represent particles?

The workshop will be held for a period of four days. The first three days will consist of three sessions:

1) Observing particles in the ocean: Methods, Results, & Lacunae

2) Role of particles in the cycle of trace elements & isotopes in the ocean

3) Transport & transformation of particles in the ocean

Each session will comprise invited keynotes followed by topical talks and then a round-table discussion.

The last day of the workshop will be used to recommend future studies that would further our understanding of ocean particles, both in the context of GEOTRACES and beyond. Although GEOTRACES is focused on TEIs, approximately 2/3 of the material to be covered at the workshop is equally relevant to the cycling of particulate biogenic phases as well, which is especially of interest to the ocean carbon community. The action items to be identified during the workshop will be reported in a journal publication in order to provide higher visibility to the output of the workshop.
