highly motivated graduate student (MS or PhD) to join an NSF-funded
collaborative project examining the organic biogeochemistry of surfactants at
the air-sea interface. The student will be advised by Dr. Andrew Wozniak at the
University of Delaware’s, School of Marine Science and Policy in Lewes, DE with
an expected start date of Fall 2021 or Winter 2022. Tuition and a competitive student
stipend will be offered for the 3-year duration of the project.</span></p>

air-sea interface, in the surface microlayer, influencing both the chemistry of
materials available for exchange and the physical environment (e.g., surface
tension, turbulence) for gas and particle transfers between air and sea. </span><span style="font-family:"Times New Roman",serif">The project seeks to develop a
mechanistic understanding of the links between biological and photochemical
processes and the resulting surfactant and surface microlayer chemical and
physical characteristics. Such an improved understanding will represent a first
step toward improved models of the air-sea exchange of climate relevant gases
and aerosols. The project is a collaboration with Dr. Amanda Frossard’s group
at the University of Georgia. Two research cruises to sample surface microlayer
and subsurface waters from estuarine, coastal ocean, and open ocean sites will
provide the student with valuable oceanographic field experience. The student
will be trained and actively involved in a subset of seawater organic matter
molecular (colorimetry and UV-vis spectroscopy; Fourier transform ion cyclotron
resonance mass spectrometry; high resolution liquid chromatograph mass
spectrometry), biological (next-generation DNA sequencing), and physical (dynamic
and equilibrium surface tension) characterization, and multivariate statistical
techniques. </span></p>
