Short Description of your Research or Creative Project (700 characters or less)

Iron is an essential nutrient in biological systems, and is the limiting nutrient in about ⅓ of the surface ocean. We investigate the flow injection method of Lohan et al., 2006, with modifications described in Biller et al., 2013 to analyze nanomolar concentrations of iron in seawater. In this work we focus on quantifying and understanding the uncertainties in the measurements and the signal of the blank by adjusting the method in four distinct ways.
