Title: Survey of dissolved inorganic carbon (DIC) and dissolved oxygen (DO) along the Duplin River in 2014
Abstract: A transect measure of inorganic carbon and oxygen level at 12 equidistant stations along the Duplin Rvier were conducted at sunrise, sunset and next sunrise for each season in 2014 in order to estimate the air-water exchange, longitudinal mixing and metabolism of the Duplin River ecosystem.
