Gradient Analysis of Carbon Monoxide and Methane in Polluted and Other Nearshore Habitats.
Abstract
A system for the determination of dissolved gases in seawater by gas chromatography was constructed and used to find the concentrations of methane and carbon monoxide in a variety of habitats around the Monterey Peninsula. Methane was shown to have a maximum of 0.00028 ml at 50 meters at the open ocean station, with a surface value of 0.00011m. The surface waters at the nearshore stations were almost three times this value. Methane was also shown to be an effective tracer for sewage effluent. The carbon monoxide maximum was found at 15 meters which correlated closely with primary productivity. The surface values were lower than the nearshore values. All stations sampled were found to be highly supersaturated with both gases. This indicates that in this area, the ocean is a major source of both methane and carbon monoxide.
