Automated determination of carbon dioxide, oxygen, and nitrogen partial pressures in surface waters
Article Abstract:
An automated system can accurately determine partial pressures of oxygen, carbon dioxide and nitrogen in surface waters. A programmable data logger-controller, an infrared CO2 analyzer, a polarographic O2 electrode, and a barometer connected to a submersed gas exchanger made of thin-walled silicone elastomer tubing are used. Metabolic and gas flux studies can be made even in highly oligotrophic waters. Data from a small oligotrophic lake provide evidence of epilimnetic supersaturation.

Biological and isotopic changes in coastal waters induced by Hurricane Gordon
Article Abstract:
Isotopic and biological changes brought on in coastal waters by Hurricane Gordon, a major storm event, are discussed as they relate to a research cruise, Nov. 1994. Results show storm-generated winds mixed sediments and dissolved nutrients with surface waters and that that brought a rapid increase in water-column primary production.

Predicting the signal of O(2) microsensors from physical dimensions, temperature, salinity, and O(2) concentration
Article Abstract:
The article describes the mathematical model for predicting the O(2) microsensor signal in temperature and salinity gradients, and the use of oxygen microsensors for hydrographic measurements. Oxygen water column profile is used to demonstrate the model.
