BN008:
Building biogeochemical bonds: Identifying the influence of macro and micro-nutrient cycling on marine carbon and nitrogen


Session ID#: 28316

Session Description:
The efficiency of the ocean’s biological carbon pump is determined by the physical transport and cycling of both macro- (N, P, Si, S, O) and micro-nutrients (e.g. Fe, Zn, Co, Cu, Cd, Ni, Mn, Mo, V, B, Se). However, even as our capability to measure nutrient concentrations and their isotopes have expanded to include basin-scale datasets, we continue to be challenged by new insights with respect to variable plankton and organic matter stoichiometry, lateral nutrient transport fluxes, ‘new’ vs. ‘recycled’ nutrients, metal-organics complexation, scavenging rates, variable remineralization rates, elemental residence times, and more. Here we welcome submissions that address macro- and micro-nutrient cycling and their effects on sustaining the marine carbon (e.g. export production) and nitrogen (e.g. nitrogen fixation, denitrification) cycles. A wide breadth of scales (meso, regional, basin, global; paleo, present, future) and scientific approaches to these questions are encouraged including observational, theoretical, modeling, and isotopic studies. Finally, we encourage submissions that work to bridge oceanographic disciplines.
