abstract = {The interface of the oceans and aqueous aerosols with air
drives many important physical and chemical processes in the
environment, including the uptake of CO2 by the oceans.
Transport across and reactions at the ocean–air boundary
are in large part determined by the chemical composition of
the interface, i.e., the first few nanometers into the
ocean. The main constituents of the interface, besides water
molecules, are dissolved ions and amphiphilic surfactants,
which are ubiquitous in nature. We have used a combination
of surface tension measurements and liquid-jet X-ray
photoelectron spectroscopy to investigate model seawater
solutions at realistic ocean-water ion concentrations in the
absence and in the presence of model surfactants. Our
investigations provide a quantitative picture of the
enhancement or reduction of the concentration of ions due to
the presence of charged surfactants at the interface. We
have also directly determined the concentration of
surfactants at the interface, which is related to the ionic
strength of the solution (i.e., the “salting out”
effect). Our results show that the interaction of ions and
surfactants can strongly change the concentration of both
classes of species at aqueous solution–air interfaces,
with direct consequences for heterogeneous reactions as well
as gas uptake and release at ocean–air interfaces.},
