Abstract
- Various biogeochemical processes complicate carbon dioxide (CO <subscript>2</subscript> ) behaviour in coastal oceans. Through eight summer surveys, detailed variations in CO <subscript>2</subscript> mechanisms in the urbanized Jiaozhou Bay, China, were analysed. During the rainless period, respiration and dissolved inorganic carbon input from treated wastewater made the northeastern region a strong CO <subscript>2</subscript> source, while the western region with cleaner seawater was a weak source because calcium carbonate (CaCO <subscript>3</subscript> ) precipitation exceeded primary production. Rainfall events with different intensities and locations caused significantly different effects. When rainfall occurred over the sea, enhanced primary production caused a CO <subscript>2</subscript> sink; when rainfall induced little terrestrial pollutant input, CaCO <subscript>3</subscript> precipitation exceeded net primary production, leading to a CO <subscript>2</subscript> source. When heavy rain caused bulk runoff, the northeastern region was a strong CO <subscript>2</subscript> source because rivers flowing through downtown regions inputted considerable organic matter, while in the western region, runoff through suburbs and wetlands led to a strong sink.<br /> (Copyright © 2019 Elsevier Ltd.
