Summary: | The uptake of carbon dioxide (CO2) from the atmosphere by seawater has caused ocean acidification globally. In addition to anthropogenic CO2 uptake, the coastal ocean experiences enhanced acidification due to freshwater discharge, eutrophication, upwelling, etc. This coastal acidification affects the health of calcifying species and has a harmful impact on commercial fisheries and the marine ecosystem. It is critical to monitor coastal acidification and determine the spatial and temporal trends of related parameters. This dissertation focuses on the carbonate/bicarbonate buffering system, which is a chemical buffer system that regulates seawater pH. I analyze the carbonate chemistry dynamics and buffer capacities for the east coast using four shipboard datasets, satellite remote sensing data, and model outputs. Results suggest that total dissolved inorganic carbon and the aragonite saturation state along the U.S. eastern continental shelf have patterns that agree with predictions based on carbon dioxide ... |
