[ES_JOBS_NET] PhD in Identifying ocean COS and CS2 sources by sulfur stable isotopes

[Alon Angert]

We are looking for a PhD student for an NSF (and BSF) funded project at the
Hebrew University of Jerusalem, Institute of Earth Sciences.
Project description:
Carbonyl sulfide (COS) is the most abundant long-lived sulfur gas in the
atmosphere, with a lifetime of a few years. COS is an important source for
background stratospheric sulfate aerosols, which have significant control
on Earth’s albedo, and hence temperature. COS is used as a promising proxy
for terrestrial gross primary production (photosynthesis), which controls
atmospheric CO2 concentration, based on the fact that COS largest sink is
through terrestrial plant stomata, which also take up CO2.
The goal of the current project is to enable a better understanding of
ocean COS and CS2 sources and sinks, both on the global and the local
scales, through the use of stable isotopes. The research will include
measurements of the sulfur isotopes ratio in COS emitted from the ocean,
and measurements of the COS isotopic fractionation during different
processes. The research will be based on lab experiments, and sampling at
sea, in cruises leaving from Israel and the USA.

Requirments:
The project requires a student with a MSc who is persistent, imitative, and
has a broad interest in Earth and ocean Sciences. During the research, the
student will use advanced equipment in the lab, and will perform sampling
in the field. The study involves the operation of cutting-edge
stable-isotopes measurements and other advanced analytical systems.
Experience with operating IRMS and/or other hands-on experience with
analytical systems is highly desirable.
