Description:
Nitrate as one of the chemical parameters of major
interest in marine biogeochemistry is detectable by means of its
optical absorption in the ultra violet spectrum, given appropriate
algorithms to correct for other seawater constituents. The
presented work outlines the potential and technical requirements
to adopt this new instrumentation in autonomous sub-surface
applications. First results from laboratory experiment as well as
from a flow-through application onboard RV POSEIDON cruise
P347 in the North Atlantic are used to characterize the sensitivity
of the method. Having long term deployment in mind, different
antifouling strategies are reviewed and evaluated in the context
of an optical sensor.
