Gas profiler for real-time CO2, N2 and O2 measurements
Craig McNeil, Graduate School of Oceanography, University or Rhode Island
2005-2006
We propose to build, test, demonstrate and make available for research a profiling system capable of real-time measurements of dissolved CO2, N2 and O2. The system will be built around a Seabird Electronics SBE19plus profiling CTD with model 43 O2 probe, a newly developed fast response gas tension device (GTD), and a newly developed fast response NDIR pCO2 sensor. The complete system will have a maximum operating depth range of 0-100 m. The three dissolved gas measurements provide a range of solubility and biological activity with which to study carbon related cycling in real-time survey mode.
