Trace Element and Nutrient Cycling in San Francisco Bay
Abstract
Our goal is to make quantitative measurements of the fluxes of trace metals (copper, cobalt, cadmium, manganese, and iron) and nutrients (ammonia, nitrate, phosphate and silicate) and gases (oxygen, carbon dioxide and 222Rn) into and out of the sediments of shallow water embayments and harbors. We seek to understand the coupling between organic matter diagenesis, pore water chemical profiles, infaunal activities, and the mobility of trace metals across the sediment-water interface. We seek to investigate metal-nutrient interactions utilizing in situ, manipulative experimentation. These measurements will be used to develop a predictive model of chemical cycling whereby the magnitude of the anthropogenic contributions of dissolved metal and nutrient species within a coastal system can be addressed. Further, we seek to advance the technologies available to conduct in situ research into shallow water sediment diagenesis and benthic biological impacts on sediment and water quality.
