The Spectrophotometric Analysis Of Lead Carbonate Complexation And Carbonate Saturation States In Seawater, Regina Anita Easley

USF Tampa Graduate Theses and Dissertations

The carbon dioxide (CO₂) system is the primary buffer in seawater which controls oceanic pH. Changes in the marine CO₂ system affect a number of processes such as metal speciation, mineral saturation states, auditory responses in fish, and primary productivity rates. Increased atmospheric concentrations of CO₂ from human activities (e.g. burning of fossil fuels, deforestation, and cement production) has led to a global decrease in surface ocean pH termed anthropogenic ocean acidification. One particular concern in response to increased oceanic CO₂ is a substantial decrease in the calcium carbonate (CaCO₃) saturation states, Ω …

Statistical Models For Environmental And Health Sciences, Yong Xu

USF Tampa Graduate Theses and Dissertations

Statistical analysis and modeling are useful for understanding the behavior of different phenomena. In this study we will focus on two areas of applications: Global warming and cancer research. Global Warming is one of the major environmental challenge people face nowadays and cancer is one of the major health problem that people need to solve.

For Global Warming, we are interest to do research on two major contributable variables: Carbon dioxide (CO2) and atmosphere temperature. We will model carbon dioxide in the atmosphere data with a system of differential equations. We will develop a differential equation for each of six …
