Characterising a New Gas Analyser for Eddy Covariance Measurements of
Air-Sea Fluxes of Carbon Dioxide
--------------------------------------------------------------------

Accurate measurements of atmosphere-ocean fluxes are important for
quantifying the amount of greenhouse gases that are transferred across
the air-sea interface.  The eddy correlation (direct) method is
considered to be the benchmark for accurate determination of air-sea
fluxes. This method relies on high-frequency measurements of the
fluctuations of vertical wind velocity (w') and gas concentration
(c'). Current gas analyser technology places constraints on the
ability to determine c' with the required signal-to-noise ratio, and
measurements are limited to conditions of high air-sea fluxes.

The main objective of this project is to characterise a
newly-developed photoacoustic gas analyser and implement it within an
eddy-covariance system.  This technology will provide a significant
improvement in sensitivity over the IR absorption sensors that are
currently in oceanographic use, and there is a very stong potential
for reducing the scatter in the air-sea gas transfer coefficient.

--------------------------------------------------------------------
Post-doctoral candidates should have completed a PhD in oceanography,
atmospheric science, or a related field with a proven research record
and evidence of high research potential. Familiarity with the eddy
covariance flux method is exceedingly desirable.  Experience with
instrumentation is essential. Enthusiasm for participation in
ocean-going field experiments is necessary.

An annual salary of €40,086 is offered for an initial period of 12
months, with the possibility of a further extension. For more
