gases. Near the Antarctic coast, the degree of undersaturation of both gases more than doubled. These decreases, however, are likely the result of enhanced vertical mixing rather than an increase in the strength of chemical or biological sinks. The minimum degradation rate constants necessary to sustain these undersaturations in the presence of air-sea exchange are in the same range as the observed total degradation rate constants measured during this cruise by the University of California at Irvine. These results further suggest that there is no significant production of methyl bromide and methyl chloride in polar waters.
