MM42B:
The Dawn of BioGEOTRACES: Metal-Microbe Interactions in the Ocean II


Session ID#: 37406

Session Description:
Trace metals are essential for life, catalysing key cellular reactions which then govern patterns of ocean fertility and biodiversity. Fundamental in this regard are the ways in which ocean microbes acquire essential metals and how biological activity is affected by metal availability. Developments in this field are being led by advances in analytical chemistry, nanotechnology, molecular biology, and bioinformatics, as well as the expansion of 'omics'-related observations of in-situ microbial communities, and the advent of new high resolution geochemical data from the international GEOTRACES program. It is now timely to bring together insights from these different disciplines, spanning observation and modelling approaches to better understand how microbial activity, diversity and ecology is shaped by interactions with trace metals over different space and time scales. By linking across disciplines, there is the potential to develop the mechanistic understanding required to inform the ecological and biogeochemical models we rely on for testing hypotheses and projecting the impacts of ocean change. We are specifically interested in contributions that address (i) metal uptake and competition between microbes for metal resources, (ii) how microbes adapt their physiology to metal scarcity and varied supply and (iii) how trace metals shape cellular function and evolution.
