A climatology and mesoscale model intercomparison of summertime Lake Ontario breezes /Comer, Neil Thomas January 1992 (has links)
The lake breeze is shown to develop on 30% of all summer days in the Toronto region, similar to other findings in the Great Lakes area. Simulations with the Colorado State University (CSU) model show that under northwest to north gradient flow the lake breeze is characterized by a broad band of westerlies over the lake, while southwesterly gradient flow produces a broad band of easterlies. A nocturnal mesoscale cyclonic eddy is predicted over western Lake Ontario under west and northwest gradient flow conditions. / A statistical model intercomparison of the CSU and Ontario Ministry of Environment models over a 19600 km$ sp2$ domain centred on Pickering, ON revealed the CSU model generally more accurately predicts the temporal and spatial lake breeze characteristics. This is attributed to improved model parameterizations and larger domain size enabling the model to resolve the full-lake scale circulations which develop.

Methane metabolism and nitrogen cycling in freshwater sediment of a polluted ecosystem : Hamilton Harbour (Canada)Roy, Réal, 1963- January 1995 (has links)
Environmental regulation of nitrogen cycling processes, denitrification and nitrification, was studied in sediment of Hamilton Harbour, with particular emphasis on the role of CH$ sb4$ metabolism (production and consumption). Through extensive sediment sampling and numerical analysis, it was found that particulate carbon was the best predictor of potential for anaerobic production of CH$ sb4$ and CO$ sb2$. The only predictor of denitrification capacity was anaerobic CO$ sb2$ production, indicating that beside NO$ sb3 sp-$ and O$ sb2$, a biotic factor involved in carbon metabolism may be important in the control of this activity. / Suppression of aerobic N$ sb2$O production in sediment slurries by C$ rm sb2H sb2$ and correlation with NO$ sb3$-production indicated that it was dependent on chemolithotrophic nitrification. Although CH$ sb4$ (1 to 24 $ mu$M) stimulated production of NO$ sb3 sp-$ and N$ sb2$O, we found that CH$ sb4$ at 84 $ mu$M or greater suppressed nitrification. Following extensive studies of pore water chemistry, potential microbial activities, and counts of nitrifiers and methanotrophs, we found that CH$ sb4$ oxidation (i) is more likely to suppress nitrification by competition for O$ sb2$ and NH$ sb4 sp+$ between methanotrophs and nitrifiers, and (ii) may be more important than nitrification as a sink of hypolimnetic O$ sb2$ in Hamilton Harbour. / Amongst a number of inhibitors, allylsulfide was found to be a differential inhibitor with much less effect on CH$ sb4$ oxidation in sediment slurries or in axenic cultures of Methylosinus trichosporium OB3b than on nitrification in sediment slurries.
