T2 - Journal of the Air Pollution Control Association AB - Sulfur compounds of biogenic origin are thought to constitute a significant fraction of the atmospheric sulfur burden. Experimental determination of the biogenic fluxes of these compounds into the atmosphere is required to assess accurately the relative contributions of the anthropogenic and the biogenic fraction of the natural sources to such important phenomena as the atmospheric sulfate burden and acid precipitation. A review of the literature describing field measurements of biogenic sulfur compounds at different kinds of emission locales to include both generation processes (sulfate reduction and plant decomposition) of volatile sulfur production show a great variation in the emission rate measurements associated primarily with wide variations in the surface and climatic environments of the various study sites. Although the maximum emission rate measurements balance the global sulfur cycle, the average measurement values do not, indicating the need for more experimental investigations in order to characterize the biogenic process adequately.

A Comparison with Deep-Water Equilibrium-Range Slope and Other Spectral Parameters AU - Knowles, C. E. T2 - Journal of Physical Oceanography AB - Spectral parameters calculated from wind-wave measurements in a finite-depth restricted-fetch estuary are compared with similar deep-water parameters. The equilibrium range of these finite-depth spectral data seems to be fitted more satisfactorily by the −3 slope predicted for constant depth by Kitaigorodskii et al. (1975) and measured for shoaling waves by Thornton (1977). Non-dimensional effective-fetch x˜e appears to be the parameter of choice for use in displaying other scaled spectral data (like wave energy ε and peak frequency ν) because it reconciles differences in ε and ν data for short (5–7 km) and long (20–42 km) fetches without having to alter the ε and ν data, but the results also suggest that using fetch as a scaling parameter may not be satisfactory. Finite-depth effects were clearly shown in the ε-x˜e data (the slope of the power-law relation was significantly larger than for deep-water relations) and in the ν-x˜e data [the slope was between the relations of Phillips (1977), Ross (1978) and Liu and Ross (1980), but well above these power-law lines]. There was remarkable agreement between this study's finite-depth ε-ν equilibrium data and the relations of Ross (1978) and Liu and Ross (1980) when kph was 0(1) or greater, with the largest departure when kph≤0.7 (where kp is the wavenumber associated with the spectral peak). In addition to the expected restriction to wave growth by bottom dissipation, refraction and shoaling, there is evidence in the data supporting the calculations of Hasselmann and Hasselmann (1980) that show that resonant wave-wave interaction cross-spectral transfer rates for finite-depth waves increase rapidly above the deep-water rates when kph2.0.co;2 VL - 12 IS - 6 SP - 556-568 J2 - J.
