Download or read book Dissolved Oxygen Dynamics in the Dunnville Marsh on the Grand River Ontario Canada written by Aseel S. Kaiser and published by . This book was released on 2009 with total page 81 pages. Available in PDF, EPUB and Kindle. Book excerpt: Dissolved oxygen (DO) is one of the most important environmental factors necessary to sustain aquatic life. The Southern Grand River is characterized with extensive marshes. This study focuses on the Dunnville Marsh in the Southern Grand River. The spatial and temporal variation in dissolved oxygen was studied in the Dunnville Marsh and the Grand River over a one year cycle during 2007 to 2008. Dunnville Marsh exhibited little influence on the oxygen regime of the river. The Grand River; however, could influence the oxygen regime in the marsh during the spring when waters are high but exerts little influence during the rest of the year. There were no great differences in DO between the wetland and the river during the high water spring melt period; however notable differences occurred in the summer and fall. Oxygen stable isotopes and diel O2 measurements showed that ecological factors probably were influencing the DO cycle in Dunnville Marsh, whereas both ecological and weather factors influenced the cycle in the Grand River.

This book was released on 1999-11-05 with total page 424 pages. Available in PDF, EPUB and Kindle. Book excerpt: This accessible volume fills a much-needed gap and addresses coreissues on how economic and environmental systems are interconnectedlooking at how economic frameworks and features of environmentalsystems can be integrated within formal models to address changesand associated resource management issues at appropriate levels:micro level and national or global level. The more the relationship between economic and environmentalsystems is studied analytically and empirically, the more aware webecome of the gap in our existing knowledge of environmental dataand process parameters. While important empirical questions areunanswered in environmental economics literature, work on theenvironmental science of ecological systems fails to raise theright questions and identify key variables in human-exploitedecosystems. This book covers: * Concepts and Methods * Land, Water and Production * Biodiversity, Preservation and Production * Pollution Externalities * The Environment and Global Economy This timely book will be of interest to environmental scientists,economists and policy makers, students, academics, and researchersinterested in ecosystems modelling, ecological economics andenvironmental resource economics.

This book was released on 2016 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The dissolved oxygen (DO) field in the Russian River estuary (RRE) was investigated during periods of mouth closure. The RRE is a bar-built, drowned-river-valley estuary located in northern California. Similar to other estuaries in Mediterranean climates, the mouth of the RRE closes episodically. The probability of closure is highest from September to November, when river flow is seasonally low, which allows sediment deposited by wave-driven processes to build a sand bar across the estuary mouth. Separation from the ocean leads to strong vertical stratification in the estuary, which impacts estuarine circulation and water properties. Of concern are the low oxygen concentrations observed in bottom waters during prolonged inlet closures. Based on 5 years of seasonal monitoring data, the pattern of oxygen distribution observed during periods of inlet closure is described and related to physical structure. The role of vertical mixing in controlling oxygen levels is then examined using a vertical 1-dimensional mass balance model. A strong pycnocline suppresses mixing, which is estimated from a vertical salt balance. The pycnocline thus also suppresses the diffusive flux of oxygen to the bottom layer, so that even low oxygen demand will eventually deplete dissolved oxygen in the water column. A one-dimensional mass balance model yields values for net ecosystem metabolism rates through the water column, showing net oxygen uptake beneath the pycnocline and net oxygen production in the photic zone above and within the pycnocline. Given the absence of mixing in the pycnocline, oxygen levels vary strongly between day and night – and most strongly during closure events when high levels of oxygen and chlorophyll are observed within the pycnocline.
