Session Description:
The distributions of trace elements in the marine environment are undeniably linked to biological processes. Low concentrations or low bioavailability of trace metals in the water column can lead to micronutrient limitation and stress, while greater availability may increase biological demand and enhance the growth of microorganisms. Recent advances in high throughput biological techniques, including “omics”, as well as high-resolution geochemical data from the GEOTRACES program (www.geotraces.org) has lead to a wealth of new data. However, meaningful interpretation of these data often still relies on process studies, incubation-based experimental work, or the culturing of representative or novel organisms. This session invites contributions on every scale of metal-microorganism interactions, ranging from small-scale mechanistic work to large-scale biogeochemical cycle studies. We encourage abstracts that investigate trace metal acquisition strategies, cellular metabolism, chemical speciation and bioavailability, and/or studies that link trace metal and biological water column data. Presentations that strive to better understand the biological control exerted on the distribution of trace elements in the marine environment are especially encouraged.
