Book Description
"Negatively buoyant jets, or sinking jets, can be observed in many problems of pollutant discharge. Any chemical waste that is heavier than the receiving water into which it is discharged may act as a negatively buoyant jet. In addition, when water is taken from the hypolimnion of a deep lake or reservoir and used as cooling water, the temperature, and consequently, the discharge may behave like a negatively buoyant jet. Two existing jet diffusion models have been utilized to predict the trajectory and dilution of a positively buoyant jet, or a rising jet, and have been modified to account for the sinking effect. Twenty-four experimental investigations were conducted involving different combinations of densimetric Froude number, velocity ratios, and initial angle of discharge. Salt was used as the tracer, yielding a fluid that was denser than the ambient receiving water and facilitated measuring concentration profiles of the jet plume. The coefficient of entrainment, the major mechanism of dilution, was determined as a function of the densimetric Froude number, velocity ratio, and initial angle of discharge. The reducted drag coefficient was chosen as zero for both models since any other value would predict a trajectory whose rise would be less than experimentally observed. For all angles of discharge the entrainment coefficient increased with a decrease in the velocity ratio and with an increase in densimetric Froude number. Additionally, there was a marked decrease in the entrainmnet coefficient with a decrease in the initial angle of discharge."--Page ii.

Managing Ocean Environments in a Changing Climate

Pages : 372
Book Description
Managing Ocean Environments in a Changing Climate summarizes the current state of several threats to the global oceans. What distinguishes this book most from previous works is that this book begins with a holistic, global-scale focus for the first several chapters and then provides an example of how this approach can be applied on a regional scale, for the Pacific region. Previous works usually have compiled local studies, which are essentially impossible to properly integrate to the global scale. The editors have engaged leading scientists in a number of areas, such as fisheries and marine ecosystems, ocean chemistry, marine biogeochemical cycling, oceans and climate change, and economics, to examine the threats to the oceans both individually and collectively, provide gross estimates of the economic and societal impacts of these threats, and deliver high-level recommendations. Nominated for a Katerva Award in 2012 in the Economy category State of the science reviews by known marine experts provide a concise, readable presentation written at a level for managers and students Links environmental and economic aspects of ocean threats and provides an economic analysis of action versus inaction Provides recommendations for stakeholders to help stimulate the development of policies that would help move toward sustainable use of marine resources and services
