In recent years, there has been a great deal of interest in the heterogeneous chemistry of
trace atmospheric gases on aqueous and solid-phase particles present in the troposphere …

Nanoparticles are discrete nanometer (10-9 m)-scale assemblies of atoms. Thus, they have
dimensions between those characteristic of ions (10-10 m) and those of macroscopic …

It has long been hypothesized that acids formed from anthropogenic pollutants and natural
emissions dissolve iron (Fe) in airborne particles, enhancing the supply of bioavailable Fe to …

The solubility of iron, aluminium, manganese and phosphorus has been determined in
aerosol samples collected between 49° N and 52° S during three cruises conducted in the …

The fraction of atmospherically deposited iron which dissolves in seawater, or becomes
available to phytoplankton for growth, is a key determinant of primary productivity in many …

Mineral dust is a complex entity containing a range of iron minerals including poorly
crystalline to crystalline iron oxides to clay minerals. Important progress has been made to …

The atmosphere is a complex medium in which several phases coexist: gas, aerosol
particles, condensed water, liquid, and ice particles. All of the interactions that may occur …

To understand the impact of dust deposition on ocean primary productivity, the evaluation of
dust input is not sufficient, and the soluble iron supply is also needed. Measurements of iron …

We report empirical estimates of the fractional solubility of aerosol iron over the Sargasso
Sea during periods characterized by high concentrations of Saharan dust (summer 2003) …

Aerosol deposition provides a major input of the essential micronutrient iron to the open
ocean. A critical parameter with respect to biological availability is the proportion of aerosol …
