Short summary
In this study, we discuss the regional variability in the fractional solubility of trace elements (Al, Ti, Fe, Mn, Co, Ni, Cu, Zn, Cd, Pb) from aerosol samples collected during three cruises to the North Atlantic Ocean. We present data that provides a solubility window, covering a conservative, lower limit to an upper limit, the maximum potentially soluble fraction, and discuss why this upper limit could be used to represent the biologically available fraction in some regions.
